a904a56c36 Older distributions (i.e. RHEL-5) don't have udevadm at all, but they do
have udevsettle.  So change our tests to prefer udevadm if it exists, but
to fall back to udevsettle if it does not.

fb23f4f4f4 tests: daemon-conf: accommodate numeric-valued config params
This test would hang when failing to perturb the soon-to-be-
added numeric (and non-boolean) valued parameters, max_clients,
max_workers, min_workers.
* tests/daemon-conf: Require that all commented-out settings
in libvirtd.conf have the same form.  Before, two parameters
were not being tested, since a space had snuck between the
leading "#" and the "param = value" parts.
Apply each RHS-value-perturbing transformation
separately, not in series.
Let VERBOSE=yes turn on debugging.
Be more verbose by default, since this is a relatively
long-running test.
* qemud/libvirtd.conf: Normalize the spacing around each setting
that is to be perturbed by tests/daemon-conf.

a9567e09ef Instead of relying solely on polling for /dev devices to appear in libvirt, we
really should be synchronizing against udev.  This is generally done by a call
to udevsettle, which is exactly what this patch implements for the storage
backends that are likely to create new /dev nodes.  I believe I've read that
even after udevsettle, you are not guaranteed that devices are all the way
created, so we still need the polling in the rest of the sources, but this
should give us a much better chance of things existing as we expect.

d20d6b1bb0 Currently libvirt can race with udev
creation of /dev/disk/by-{id,path}, so if we fail to open the directory, retry
up to 5 seconds.  This is only likely to happen on hosts that are:

1) diskless (so /dev/disk/by-{id,path} doesn't exist already), and
2) slow, and/or heavily loaded (meaning that udev can take some time to create
the /dev nodes).

volumes is /dev/disk/by-id/scsi-S_beaf11, then you would be able to
call virStorageVolLookupByPath("/dev/sdc"), and get the correct volume
back.

e3b792d6e3 An updated patch for adding <device> tags to logical
findPoolSources.  Given danpb's last feedback, I completely removed the XML
parsing and did it all with structures.  The result should (hopefully) be a lot
easier on the eyes, and is a little more generic.

c0c0fb8eef As suggested by danpb, to fix up the regression caused by last week's VIR_ENUM
cleanup patch, add a ".defaultFormat" member to .poolOptions.  In
storage_conf.c, if virXPathString(/pool/source/format/@type) returns NULL, then
set the pool type to .defaultFormat; otherwise, lookup the type via
formatFromString.

6d035f67e0 Fix syntax error that was breaking RPM builds. 2008-10-22 13:55:15 +00:00
c6f0a7b2db Currently, you can define a logical storage pool with something like:
<pool type='logical'>
	<source>
		<name>MyVG</name>
		<device name='/dev/sdb'/>
...

However, dumping out the XML for this same storage pool (with, say, virsh
pool-dumpxml), gives:

<pool type='logical'>
	<source>
		<name>MyVG</name>
		<device name='/dev/sdb'>
		</device>


To make this more idempotent, do the <device name='/dev/sdb'/> form by default,
and only do the <device>...</device> form if .nfreeExtent is defined for the
storage pool.

c83c3e9e5c While doing on this patch series, I mistakenly added a bogus piece of
storage XML to libvirtd, which was saved in /etc/libvirt/storage.  On subsequent
stop/start of libvirtd, because of another bug , an
error wasn't being set properly in an error path, so libvirtd was SEGV'ing in
storage_conf.c:virStoragePoolObjLoad when trying to dereference the NULL err
returned from virGetLastError().  Make this more robust against errors by always
doing "err ? err->message : NULL" in the printf.  I looked around the tree and
found a couple of other places that weren't guarded, so this patch fixes them as
well.

eeff3cdcbc Add support for detecting the partition table type when scanning
iSCSI volumes.  This is implemented in the
virStorageBackendUpdateVolInfoFD function, so all future callers will
automatically benefit.  This is a somewhat large patch because the
conversion of the virStorageBackendPartTableTypeToString necessitated
a change to the formatToString and formatFromString function pointers,
which caused fallout in other places in the storage stuff.  The good
news is that most of these callers are now converted over to the
VIR_ENUM_IMPL, which means a lot of redundant code is now gone.

df01e14bd7 Add LXC version implementation
This patch adds an implementation of the version function to the LXC driver.
The providers use the hypervisor version in a field of one of the instances,
so we need to have something meaningful here.  AFAICT, the only real option
we have (considering the limitations of the libvirt version information) is
to use the kernel version.

b8fb68be37 DanB pointed out that my sexpr xend_internal patch from yesterday broke one of
the regression tests.  The problem is that the xenDaemonFormatSxpr{Disk,Net}
functions are shared between domain creation time and attaching disk time.
Unfortunately, though, Xend expects something different during these two times.
 During domain creation time, it wants the "(device" in front of the sexpr,
while during attach time it does not.  To remedy this situation, I added a flag
to these two functions to differentiate between these two modes.  With this
patch in place, all of the regression tests pass.

6335c2a0cc With the recent refactoring of the domain code, plus the changes with the Xend
code, a couple of bugs were introduced into the attach-disk and attach-interface
functionality.  This patch fixes 3 bugs:

1)  In xenDaemonAttachDevice(), there is a switch statement to determine which
of the xenDaemonFormatSxpr{Disk,Net} functions to call.  Unfortunately, the case
statements are all missing the corresponding "break", so we always fall-through
to the default error case.  This patch just adds the appropriate break statements.

2)  (minor) In xenDaemonDomainDefineXML (that's a mouthful!), there is a stray
"fprintf".  This is now converted to a proper virXendError().

3)  xenDaemonFormatSxpr{Disk,Net} were adding an extra (device to the front of
the sexpr expressions that xend did not expect (this is Xend on RHEL 5.2).
Because of this, the attaches would fail.  The patch fixes this by removing the
(device from the front, which makes attach-disk and attach-interface work again.

8c30002862 Recently upstream Xen added support for having xvd devices > 16. For the most
part, this doesn't really concern libvirt, since for things like attach and
detach we just pass it through and let xend worry about whether it is supported
or not.  The one place this breaks down is in the stats collecting code, where
we need to figure out the device number so we can go digging in /sys for the
statistics.

To remedy this, I've re-written xenLinuxDomainDeviceID() to use regular
expressions to figure out the device number from the name.  The major advantage
is that now xenLinuxDomainDeviceID() looks fairly identical to
tools/python/xen/util/blkif.py (in the Xen sources), so that adding additional
devices in the future should be much easier.  It also reduces the size of the
code, and, in my opinion, the code complexity.

With this patch in place, I was able to get block statistics both on older style
devices (/dev/xvda) and on the new, expanded devices (/dev/xvdaa).

6f17fb2851 From Charles Duffy:
Per subject; if autoport is in use for a host, the current
virDomainGraphicsDefFormat code always emits "port=-1", even if a port
is assigned to the host; this leaves no way for a client to find the VNC
port assigned to the host in question.

This patches fixes it by putting the vncport in place if there is one, and
only putting "-1" if we fail that test.

654c5714bf The new generic domain re-factor introduced a small regression into the drive
handling code.  In particular, if you had a section of XML like:

    <disk type='file' device='cdrom'>
      <target dev='hdc' bus='ide'/>
      <readonly/>
    </disk>

This used to work with older libvirt, but now fails.  This is because we are
actually passing the literal string (null) to the qemu command-line, which qemu
barfs on.  This patch fixes it up by making it blank, which allows qemu to
continue on it's merry way.

2dc11b36a1 Update the changelog to go along with my commits for the last week. 2008-06-19 14:22:54 +00:00
0aa6eedddd For 0.4.3, danpb's new memory management scheme went into libvirt. This is
fine, except that is subtly alters the semantics of malloc(), calloc(), and
realloc().  In particular, if you say:

foo = malloc(0);

glibc will happily return a non-NULL pointer to you.  However, with the new
memory management stuff, if you say:

foo = VIR_ALLOC(0);

you will actually get a NULL pointer back.  Personally, I think this is a
dangerous deviation from malloc() semantics that everyone is used to, and is
indeed causing problems with the remote driver.  The short of it is that the
remote driver allocates memory on behalf of the remote side using VIR_ALLOC_N,
and this call is returning NULL so that the NULL checks elsewhere in the code
fire and return failure.

The attached patch fixes this situation by removing the 0 checks from the memory
allocation paths, and just lets them fall through to the normal malloc(),
calloc(), or realloc() routines, restoring old semantics.

a24b1d9eda When doing the conversion to danpb's new memory API, a small bug was
introduced into the qemudNetworkIfaceConnect() function.  In particular, there
is a call:

    if (VIR_ALLOC_N(vm->tapfds, vm->ntapfds+2) < 0)
        goto no_memory;

However, the tapfds structure is used to track *all* of the tap fds, and is
called once for each network that is being attached to the domain.  VIR_ALLOC_N
maps to calloc().  So the first network would work just fine, but if you had
more than one network, subsequent calls to this function would blow away the
stored fd's that were already there and fill them all in with zeros.  This
causes multiple problems, from the qemu domains not starting properly to
improper cleanup on shutdown.  The attached patch just changes the VIR_ALLOC_N()
to a VIR_REALLOC_N(), and everything is happy again.

0de4f35ebc This rather large patch rewrites the virStorageBackendISCSIFindLUNs() function
to only rely on sysfs for finding LUNs, given a session number.  Along the way,
it also fixes the bug where we wouldn't find LUNs for older kernels (with the
block:sda format), and also fixes a race condition where we could try
to find the LUN before udev has finished connecting it.

This patch fixes a few different bugs:
1) We weren't finding LUNs on pre 2.6.24 kernels
2) libvirtd sysfs scanning was racing with udev, so we didn't always see LUNs
3) We weren't showing the 0'th LUN, although that can be a valid LUN

a75a612ad5 This patch changes things around so that virStorageBackendRunProgRegex() does
*not* virStorageReportError() if the fork()/exec() process it spawned returned a
!= 0 exit code.  Rather, it returns the exitcode in this case, and it is up to
the higher level to determine whether this is a fatal error or not.  The use
case for this change is in the iSCSI stuff; older versions of iscsiadm tools
would return a failure when getting the session number, despite the command
succeeding.

f011f263a1 plug two leaks

a770c2ab1c * src/xml.c: Include "c-ctype.h". 2008-05-16 14:18:38 +00:00
c1ee35af3b start using c-ctype functions
Up to now, we've been avoiding ctype functions like isspace, isdigit,
etc.  because they are locale-dependent.  Now that we have the c-ctype
functions, we can start using *them*, to make the code more readable
with changes like these:

-        /* This may not work on EBCDIC. */
-        if ((*p >= 'a' && *p <= 'z') ||
-            (*p >= 'A' && *p <= 'Z') ||
-            (*p >= '0' && *p <= '9'))
+        if (c_isalnum(*p))

-    while ((*cur >= '0') && (*cur <= '9')) {
+    while (c_isdigit(*cur)) {

Also, some macros in conf.c used names that conflicted with
standard meaning of "BLANK" and "SPACE", so I've adjusted them
to be in line with the definition of e.g., isblank.
In addition, I've wrapped those statement macros with do {...} while (0),
so that we can't forget the ";" after a use.  There was one like that
already (fixed below).  The missing semicolon would mess up automatic
indenting.

Libvirt contributor guidelines
==============================
General tips for contributing patches
=====================================
(1) Discuss any large changes on the mailing list first. Post patches
early and listen to feedback.
(2) Post patches in unified diff format. A command similar to this
should work:
diff -urp libvirt.orig/ libvirt.modified/ > libvirt-myfeature.patch
or:
cvs diff -up > libvirt-myfeature.patch
(3) Split large changes into a series of smaller patches, self-contained
if possible, with an explanation of each patch and an explanation of how
the sequence of patches fits together.
(4) Make sure your patches apply against libvirt CVS. Developers
only follow CVS and don't care much about released versions.
(5) Run the automated tests on your code before submitting any changes.
In particular, configure with compile warnings set to -Werror:
./configure --enable-compile-warnings=error
and run the tests:
make check
make syntax-check
make -C tests valgrind
The latter test checks for memory leaks.
(6) Update tests and/or documentation, particularly if you are adding
a new feature or changing the output of a program.
There is more on this subject, including lots of links to background
reading on the subject, on this page:
http://et.redhat.com/~rjones/how-to-supply-code-to-open-source-projects/
Code indentation
================
Libvirt's C source code generally adheres to some basic code-formatting
conventions. The existing code base is not totally consistent on this
front, but we do prefer that contributed code be formatted similarly.
In short, use spaces-not-TABs for indentation, use 4 spaces for each
indentation level, and other than that, follow the K&R style.
If you use Emacs, add the following to one of one of your start-up files
(e.g., ~/.emacs), to help ensure that you get indentation right:
;;; When editing C sources in libvirt, use this style.
(defun libvirt-c-mode ()
"C mode with adjusted defaults for use with libvirt."
(interactive)
(c-set-style "K&R")
(setq indent-tabs-mode nil) ; indent using spaces, not TABs
(setq c-indent-level 4)
(setq c-basic-offset 4))
(add-hook 'c-mode-hook
'(lambda () (if (string-match "/libvirt" (buffer-file-name))
(libvirt-c-mode))))
Code formatting (especially for new code)
=========================================
With new code, we can be even more strict.
Please apply the following function (using GNU indent) to any new code.
Note that this also gives you an idea of the type of spacing we prefer
around operators and keywords:
indent-libvirt()
{
indent -bad -bap -bbb -bli4 -br -ce -brs -cs -i4 -l75 -lc75 \
-sbi4 -psl -saf -sai -saw -sbi4 -ss -sc -cdw -cli4 -npcs -nbc \
--no-tabs "$@"
}
Note that sometimes you'll have to postprocess that output further, by
piping it through "expand -i", since some leading TABs can get through.
Usually they're in macro definitions or strings, and should be converted
anyhow.
Low level memory management
===========================
Use of the malloc/free/realloc/calloc APIs is deprecated in the libvirt
codebase, because they encourage a number of serious coding bugs and do
not enable compile time verification of checks for NULL. Instead of these
routines, use the macros from memory.h
- eg to allocate a single object:
virDomainPtr domain;
if (VIR_ALLOC(domain) < 0) {
__virRaiseError(VIR_ERROR_NO_MEMORY)
return NULL;
}
- eg to allocate an array of objects
virDomainPtr domains;
int ndomains = 10;
if (VIR_ALLOC_N(domains, ndomains) < 0) {
__virRaiseError(VIR_ERROR_NO_MEMORY)
return NULL;
}
- eg to allocate an array of object pointers
virDomainPtr *domains;
int ndomains = 10;
if (VIR_ALLOC_N(domains, ndomains) < 0) {
__virRaiseError(VIR_ERROR_NO_MEMORY)
return NULL;
}
- eg to re-allocate the array of domains to be longer
ndomains = 20
if (VIR_REALLOC_N(domains, ndomains) < 0) {
__virRaiseError(VIR_ERROR_NO_MEMORY)
return NULL;
}
- eg to free the domain
VIR_FREE(domain);
String comparisons
==================
Do not use the strcmp, strncmp, etc functions directly. Instead use
one of the following semantically named macros
- For strict equality:
STREQ(a,b)
STRNEQ(a,b)
- For case sensitive equality:
STRCASEEQ(a,b)
STRCASENEQ(a,b)
- For strict equality of a substring:
STREQLEN(a,b,n)
STRNEQLEN(a,b,n)
- For case sensitive equality of a substring:
STRCASEEQLEN(a,b,n)
STRCASENEQLEN(a,b,n)
- For strict equality of a prefix:
STRPREFIX(a,b)
Variable length string buffer
=============================
If there is a need for complex string concatenations, avoid using
the usual sequence of malloc/strcpy/strcat/snprintf functions and
make use of the virBuffer API described in buf.h
eg typical usage is as follows:
char *
somefunction(...) {
virBuffer buf = VIR_BUFFER_INITIALIZER;
...
virBufferAddLit(&buf, "<domain>\n");
virBufferVSprint(&buf, " <memory>%d</memory>\n", memory);
...
virBufferAddLit(&buf, "</domain>\n");
....
if (virBufferError(&buf)) {
__virRaiseError(...);
return NULL;
}
return virBufferContentAndReset(&buf);
}
Include files
=============
There are now quite a large number of include files, both libvirt
internal and external, and system includes. To manage all this
complexity it's best to stick to the following general plan for all
*.c source files:
/*
* Copyright notice
* ....
* ....
* ....
*
*/
#include <config.h> Must come first in every file.
#include <stdio.h> Any system includes you need.
#include <string.h>
#include <limits.h>
#if HAVE_NUMACTL Some system includes aren't supported
#include <numa.h> everywhere so need these #if defences.
#endif
#include "internal.h" Include this first, after system includes.
#include "util.h" Any libvirt internal header files.
#include "buf.h"
static myInternalFunc () The actual code.
{
...
Of particular note: *DO NOT* include libvirt/libvirt.h or
libvirt/virterror.h. It is included by "internal.h" already and there
are some special reasons why you cannot include these files
explicitly.
Libvirt commiters guidelines
============================
The AUTHORS files indicates the list of people with commit acces right
who can actually merge the patches.
The general rule for commiting patches is to make sure it has been reviewed
properly in the mailing-list first, usually if a couple of persons gave an
ACK or +1 to a patch and nobody raised an objection on the list it should
be good to go. If the patch touches a part of the code where you're not the
main maintainer or not have a very clear idea of how things work, it's better
to wait for a more authoritative feedback though. Before commiting please
also rebuild locally and run 'make check syntax-check' and make sure they
don't raise error. Try to look for warnings too for example configure with
--enable-compile-warnings=error
which adds -Werror to compile flags, so no warnings get missed
Exceptions to that 'review and approval on the list first' is fixing failures
to build:
- if a recently commited patch breaks compilation on a platform
or for a given driver then it's fine to commit a minimal fix
directly without getting the review feedback first
- similary if make check or make syntax-chek breaks, if there is
an obvious fix, it's fine to commit immediately
The patch should still be sent to the list (or tell what the fix was if
trivial) and 'make check syntax-check' should pass too before commiting
anything
Similary fixes for documentation and code comments can be managed
in the same way, but still make sure they get reviewed if non-trivial.

<a href="FAQ.html#Installati">Installation</a>

<h3><a name="License" id="License">License</a>(s)</h3>
<ol>
<li>
<em>Licensing Terms for libvirt</em>
<p>libvirt is released under the <a href="http://www.opensource.org/licenses/lgpl-license.html">GNU Lesser
General Public License</a>, see the file COPYING.LIB in the distribution
for the precise wording. The only library that libvirt depends upon is
the Xen store access library which is also licenced under the LGPL.</p>
</li>
<li>
<em>Can I embed libvirt in a proprietary application ?</em>
<p>Yes. The LGPL allows you to embed libvirt into a proprietary
application. It would be graceful to send-back bug fixes and improvements
as patches for possible incorporation in the main development tree. It
will decrease your maintenance costs anyway if you do so.</p>
</li>
</ol>
<h3>
<a name="Installati" id="Installati">Installation</a>
</h3>
<ol>
<li><em>Where can I get libvirt</em> ?
<p>The original distribution comes from <a href="ftp://libvirt.org/libvirt/">ftp://libvirt.org/libvirt/</a>.</p>
</li>
<li>
<em>I can't install the libvirt/libvirt-devel RPM packages due to
failed dependencies</em>
<p>The most generic solution is to re-fetch the latest src.rpm , and
rebuild it locally with</p>
<p><code>rpm --rebuild libvirt-xxx.src.rpm</code>.</p>
<p>If everything goes well it will generate two binary rpm packages (one
providing the shared libs and virsh, and the other one, the -devel
package, providing includes, static libraries and scripts needed to build
applications with libvirt that you can install locally.</p>
<p>One can also rebuild the RPMs from a tarball:</p>
<p>
<code>rpmbuild -ta libdir-xxx.tar.gz</code>
</p>
<p>Or from a configured tree with:</p>
<p>
<code>make rpm</code>
</p>
</li>
<li>
<em>Failure to use the API for non-root users</em>
<p>Large parts of the API may only be accessible with root privileges,
however the read only access to the xenstore data doesnot have to be
forbidden to user, at least for monitoring purposes. If "virsh dominfo"
fails to run as an user, change the mode of the xenstore read-only socket
with:</p>
<p>
<code>chmod 666 /var/run/xenstored/socket_ro</code>
</p>
<p>and also make sure that the Xen Daemon is running correctly with local
HTTP server enabled, this is defined in
<code>/etc/xen/xend-config.sxp</code> which need the following line to be
enabled:</p>
<p>
<code>(xend-http-server yes)</code>
</p>
<p>If needed restart the xend daemon after making the change with the
following command run as root:</p>
<p>
<code>service xend restart</code>
</p>
</li>
</ol>
<h3>
<a name="Compilatio" id="Compilatio">Compilation</a>
</h3>
<ol>
<li>
<em>What is the process to compile libvirt ?</em>
<p>As most UNIX libraries libvirt follows the "standard":</p>
<p>
<code>gunzip -c libvirt-xxx.tar.gz | tar xvf -</code>
</p>
<p>
<code>cd libvirt-xxxx</code>
</p>
<p>
<code>./configure --help</code>
</p>
<p>to see the options, then the compilation/installation proper</p>
<p>
<code>./configure [possible options]</code>
</p>
<p>
<code>make</code>
</p>
<p>
<code>make install</code>
</p>
<p>At that point you may have to rerun ldconfig or a similar utility to
update your list of installed shared libs.</p>
</li>
<li>
<em>What other libraries are needed to compile/install libvirt ?</em>
<p>Libvirt requires libxenstore, which is usually provided by the xen
packages as well as the public headers to compile against libxenstore.</p>
</li>
<li>
<em>I use the CVS version and there is no configure script</em>
<p>The configure script (and other Makefiles) are generated. Use the
autogen.sh script to regenerate the configure script and Makefiles,
like:</p>
<p>
<code>./autogen.sh --prefix=/usr --disable-shared</code>
</p>
</li>
</ol>
<h3><a name="Developer" id="Developer">Developer</a> corner</h3>
<ol>
<li>
<em>Troubles compiling or linking programs using libvirt</em>
<p>To simplify the process of reusing the library, libvirt comes with
pkgconfig support, which can be used directly from autoconf support or
via the pkg-config command line tool, like:</p>
<p>
<code>pkg-config libvirt --libs</code>
</p>
</li>
</ol>

</dd><dt><a href="http://virt-manager.org/">virt-image</a></dt><dd>
Provides a way to deploy virtual appliances. It defines a
simplified portable XML format describing the pre-requisites
of a virtual machine. At time of deployment this is translated
into the domain XML format for execution under any libvirt
hypervisor meeting the pre-requisites.
</dd><dt><a href="http://et.redhat.com/~rjones/virt-df/">virt-df</a></dt><dd>
Examine the utilization of each filesystem in a virtual machine
from the comfort of the host machine. This tool peeks into the

<h2>Web applications</h2>
<dl><dt><a href="http://ovirt.org/">oVirt</a></dt><dd>
oVirt provides the ability to manage large numbers of virtual
machines across an entire data center of hosts. It integrates
with FreeIPA for Kerberos authentication, and in the future,
certificate management.
</dd></dl>
<h2>LiveCD / Appliances</h2>
<dl><dt><a href="http://et.redhat.com/~rjones/virt-p2v/">virt-p2v</a></dt><dd>
A tool for converting a physical machine into a virtual machine. It
is a LiveCD which is booted on the machine to be converted. It collects
a little information from the user and then copies the disks over to
a remote machine and defines the XML for a domain to run the guest.
</dd></dl>
<h2>Monitoring plugins</h2>
<dl><dt><a href="http://honk.sigxcpu.org/projects/libvirt/#munin">for munin</a></dt><dd>
The plugins provided by Guido Günther allows to monitor various things

<dt><a href="http://ovirt.org/">oVirt</a></dt>
<dd>
oVirt provides the ability to manage large numbers of virtual
machines across an entire data center of hosts. It integrates
with FreeIPA for Kerberos authentication, and in the future,
certificate management.

<h2>LiveCD / Appliances</h2>
<dl>
<dt><a href="http://et.redhat.com/~rjones/virt-p2v/">virt-p2v</a></dt>
<dd>
A tool for converting a physical machine into a virtual machine. It
is a LiveCD which is booted on the machine to be converted. It collects
a little information from the user and then copies the disks over to
a remote machine and defines the XML for a domain to run the guest.
</dd>
</dl>
<h2>Monitoring plugins</h2>
<dl>
<dt><a href="http://honk.sigxcpu.org/projects/libvirt/#munin">for munin</a></dt>
<dd>
The plugins provided by Guido Günther allows to monitor various things
like network and block I/O with
<a href="http://munin.projects.linpro.no/">Munin</a>.

<dt><a href="http://collectd.org/plugins/libvirt.shtml">for collectd</a></dt>
<dd>
The libvirt-plugin is part of <a href="http://collectd.org/">collectd</a>
and gather statistics about virtualized guests on a system. This
way, you can collect CPU, network interface and block device usage
for each guest without installing collectd on the guest systems.
or a full description of available please refer to the libvirt section
in the collectd.conf(5) manual page.

If libvirt does not contain support for PolicyKit, then access control for
the UNIX domain socket is done using traditional file user/group ownership
and permissions. There are 2 sockets, one for full read-write access, the
other for read-only access. The RW socket will be restricted (mode 0700) to
only allow the <code>root</code> user to connect. The read-only socket will
be open access (mode 0777) to allow any user to connect.

<p>
To allow non-root users greater access, the <code>libvirtd.conf</code> file
can be edited to change the permissions via the <code>unix_sock_rw_perms</code>,
config parameter and to set a user group via the <code>unix_sock_group</code>
parameter. For example, setting the former to mode <code>0770</code> and the
latter <code>wheel</code> would let any user in the wheel group connect to

The default policy can be overridden by the administrator using the PolicyKit

<h1 >Access control</h1>
<p>
When connecting to libvirt, some connections may require client
authentication before allowing use of the APIs. The set of possible
authentication mechanisms is administrator controlled, independent
of applications using libvirt.
</p>
<ul>
<li>
<a href="#ACL_server_config">Server configuration</a>
</li>
<li>
<a href="#ACL_server_unix_perms">UNIX socket permissions/group</a>
</li>
<li>
<a href="#ACL_server_polkit">UNIX socket PolicyKit auth</a>
</li>
<li>
<a href="#ACL_server_username">Username/password auth</a>
</li>
<li>
<a href="#ACL_server_kerberos">Kerberos auth</a>
</li>
</ul>
<h3><a name="ACL_server_config">Server configuration</a></h3>
<p>
The libvirt daemon allows the administrator to choose the authentication
mechanisms used for client connections on each network socket independently.
This is primarily controlled via the libvirt daemon master config file in
<code>/etc/libvirt/libvirtd.conf</code>. Each of the libvirt sockets can
have its authentication mechanism configured independently. There is
currently a choice of <code>none</code>, <code>polkit</code>, and <code>sasl</code>.
The SASL scheme can be further configured to choose between a large
number of different mechanisms.
</p>
<h3><a name="ACL_server_unix_perms">UNIX socket permissions/group</a></h3>
<p>
If libvirt does not contain support for PolicyKit, then access control for
the UNIX domain socket is done using traditional file user/group ownership
and permissions. There are 2 sockets, one for full read-write access, the
other for read-only access. The RW socket will be restricted (mode 0700) to
only allow the <code>root</code> user to connect. The read-only socket will
be open access (mode 0777) to allow any user to connect.
</p>
<p>
To allow non-root users greater access, the <code>libvirtd.conf</code> file
can be edited to change the permissions via the <code>unix_sock_rw_perms</code>,
config parameter and to set a user group via the <code>unix_sock_group</code>
parameter. For example, setting the former to mode <code>0770</code> and the
latter <code>wheel</code> would let any user in the wheel group connect to
the libvirt daemon.
</p>
<h3><a name="ACL_server_polkit">UNIX socket PolicyKit auth</a></h3>
<p>
If libvirt contains support for PolicyKit, then access control options are
more advanced. The <code>unix_sock_auth</code> parameter will default to
<code>polkit</code>, and the file permissions will default to <code>0777</code>
even on the RW socket. Upon connecting to the socket, the client application
will be required to identify itself with PolicyKit. The default policy for the
RW daemon socket will require any application running in the current desktop
session to authenticate using the user's password. This is akin to <code>sudo</code>
auth, but does not require that the client application ultimately run as root.
Default policy will still allow any application to connect to the RO socket.
</p>
<p>
The default policy can be overridden by the administrator using the PolicyKit
master configuration file in <code>/etc/PolicyKit/PolicyKit.conf</code>. The
<code>PolicyKit.conf(5)</code> manual page provides details on the syntax
available. The two libvirt daemon actions available are named <code>org.libvirt.unix.monitor</code>
for the RO socket, and <code>org.libvirt.unix.manage</code> for the RW socket.
</p>
<p>
As an example, to allow a user <code>fred</code>full access to the RW socket,
while requiring <code>joe</code> to authenticate with the admin password,
would require adding the following snippet to <code>PolicyKit.conf</code>.
</p>
<pre>
&lt;match action="org.libvirt.unix.manage"&gt;
&lt;match user="fred"&gt;
&lt;return result="yes"/&gt;
&lt;/match&gt;
&lt;/match&gt;
&lt;match action="org.libvirt.unix.manage"&gt;
&lt;match user="joe"&gt;
&lt;return result="auth_admin"/&gt;
&lt;/match&gt;
&lt;/match&gt;
</pre>
<h3><a name="ACL_server_username">Username/password auth</a></h3>
<p>
The plain TCP socket of the libvirt daemon defaults to using SASL for authentication.
The SASL mechanism configured by default is DIGEST-MD5, which provides a basic
username+password style authentication. It also provides for encryption of the data
stream, so the security of the plain TCP socket is on a par with that of the TLS
socket. If desired the UNIX socket and TLS socket can also have SASL enabled by
setting the <code>auth_unix_ro</code>, <code>auth_unix_rw</code>, <code>auth_tls</code>
config params in <code>libvirt.conf</code>.
</p>
<p>
Out of the box, no user accounts are defined, so no clients will be able to authenticate
on the TCP socket. Adding users and setting their passwords is done with the <code>saslpasswd2</code>
command. When running this command it is important to tell it that the appname is <code>libvirt</code>.
As an example, to add a user <code>fred</code>, run
</p>
<pre>
# saslpasswd2 -a libvirt fred
Password: xxxxxx
Again (for verification): xxxxxx
</pre>
<p>
To see a list of all accounts the <code>sasldblistusers2</code> command can be used.
This command expects to be given the path to the libvirt user database, which is kept
in <code>/etc/libvirt/passwd.db</code>
</p>
<pre>
# sasldblistusers2 -f /etc/libvirt/passwd.db
fred@t60wlan.home.berrange.com: userPassword
</pre>
<p>
Finally, to disable a user's access, the <code>saslpasswd2</code> command can be used
again:
</p>
<pre>
# saslpasswd2 -a libvirt -d fred
</pre>
<h3><a name="ACL_server_kerberos">Kerberos auth</a></h3>
<p>
The plain TCP socket of the libvirt daemon defaults to using SASL for authentication.
The SASL mechanism configured by default is DIGEST-MD5, which provides a basic
username+password style authentication. To enable Kerberos single-sign-on instead,
the libvirt SASL configuration file must be changed. This is <code>/etc/sasl2/libvirt.conf</code>.
The <code>mech_list</code> parameter must first be changed to <code>gssapi</code>
instead of the default <code>digest-md5</code>. If SASL is enabled on the UNIX
and/or TLS sockets, Kerberos will also be used for them. Like DIGEST-MD5, the Kerberos
mechanism provides data encryption of the session.
</p>
<p>
Some operating systems do not install the SASL kerberos plugin by default. It
may be necessary to install a sub-package such as <code>cyrus-sasl-gssapi</code>.
To check whether the Kerberos plugin is installed run the <code>pluginviewer</code>
program and verify that <code>gssapi</code> is listed,eg:

Re-enter password for principal "libvirt/foo.example.com@EXAMPLE.COM":

<h1>Bug reporting</h1>
<p>
The <a href="http://bugzilla.redhat.com">Red Hat Bugzilla Server</a>
should be used to report bugs and request features against libvirt.
Before submitting a ticket, check the existing tickets to see if
the bug/feature is already tracked.
</p>
<h2>General libvirt bug reports</h2>
<p>
If you are using official libvirt binaries from a Linux distribution
check below for distribution specific bug reporting policies first.
For general libvirt bug reports, from self-built releases, CVS snapshots
and any other non-distribution supported builds, enter tickets under
the <code>Virtualization Tools</code> product and the <code>libvirt</code>
component.

<h2>Linux Distribution specific bug reports</h2>
<ul><li>
If you are using official binaries from a <strong>Fedora distribution</strong>, enter
tickets against the <code>Fedora</code> product and the <code>libvirt</code>
component.

If you are using official binaries from <strong>Red Hat Enterprise Linux distribution</strong>,
tickets against the <code>Red Hat Enterprise Linux 5</code> product and
the <code>libvirt</code> component.
<ul><li><a href="">View Red Hat Enterprise Linux libvirt tickets</a></li><li><a href="http://bugzilla.redhat.com/bugzilla/enter_bug.cgi?product=Red%20Hat%20Enterprise%20Linux%205&amp;component=libvirt">New Red Hat Enterprise Linux libvirt ticket</a></li></ul></li><li>
If you are using official binaries from another Linux distribution first
follow their own bug reporting guidelines.
</li></ul>
<h2>How to file high quality bug reports</h2>
<p>
To increase the likelihood of your bug report being addressed it is
important to provide as much information as possible. When filing
libvirt bugs use this checklist to see if you are providing enough
information:
</p>
<ul><li>The version number of the libvirt build, or date of the CVS
checkout</li><li>The hardware architecture being used</li><li>The name of the hypervisor (Xen, QEMU, KVM)</li><li>The XML config of the guest domain if relevant</li><li>For Xen hypervisor, the XenD logfile from /var/log/xen</li><li>For QEMU/KVM, the domain logfile from /var/log/libvirt/qemu</li></ul>
<p>
If requesting a new feature attach any available patch to the ticket
and also email the patch to the libvirt mailing list for discussion

<h1>Deployment</h1>
<h2>Pre-packaged releases</h2>
<p>
The libvirt API is now available in all major Linux distributions
so the simplest deployment approach is to use your distributions'
package management software to install the <code>libvirt</code>
module.
</p>
<h2>Self-built releases</h2>
<p>
libvirt uses GNU autotools for its build system, so deployment
follows the usual process of <code>configure; make ; make install</code>
</p>
<pre>
# ./configure --prefix=$HOME/usr
# make
# make install
</pre>
<h2>Built from CVS / GIT</h2>
<p>
When building from CVS it is necessary to generate the autotools
support files. This requires having <code>autoconf</code>,
<code>automake</code>, <code>libtool</code> and <code>intltool</code>
installed. The process can be automated with the <code>autogen.sh</code>
script.

</pre><p>This function allows you to read the contents of a domain's disk device. Typical uses for this are to determine if the domain has written a Master Boot Record (indicating that the domain has completed installation), or to try to work out the state of the domain's filesystems. (Note that in the local case you might try to open the block device or file directly, but that won't work in the remote case, nor if you don't have sufficient permission. Hence the need for this call). 'path' must be a device or file corresponding to the domain. In other words it must be the precise string returned in a &lt;disk&gt;&lt;source dev='...'/&gt;&lt;/disk&gt; from virDomainGetXMLDesc. 'offset' and 'size' represent an area which must lie entirely within the device or file. 'size' may be 0 to test if the call would succeed. 'buffer' is the return buffer and must be at least 'size' bytes. NB. The remote driver imposes a 64K byte limit on 'size'. For your program to be able to work reliably over a remote connection you should split large requests to &lt;= 65536 bytes.</p>

If a hypervisor supports renaming domains during migration, then you may set the dname parameter to the new name (otherwise it keeps the same name). If this is not supported by the hypervisor, dname must be NULL or else you will get an error. Since typically the two hypervisors connect directly to each other in order to perform the migration, you may need to specify a path from the source to the destination. This is the purpose of the uri parameter. If uri is NULL, then libvirt will try to find the best method. Uri may specify the hostname or IP address of the destination host as seen from the source. Or uri may be a URI giving transport, hostname, user, port, etc. in the usual form. Refer to driver documentation for the particular URIs supported. The maximum bandwidth (in Mbps) that will be used to do migration can be specified with the bandwidth parameter. If set to 0, libvirt will choose a suitable default. Some hypervisors do not support this feature and will return an error if bandwidth is not 0. To see which features are supported by the current hypervisor, see virConnectGetCapabilities, /capabilities/host/migration_features. There are many limitations on migration imposed by the underlying technology - for example it may not be possible to migrate between different processors even with the same architecture, or between different types of hypervisor.</p>

<h1>Downloads</h1>
<h2>Official Releases</h2>
<p>
The latest versions of the libvirt C library can be downloaded from:
</p>
<ul><li><a href="ftp://libvirt.org/libvirt/">libvirt.org FTP server</a></li><li><a href="http://libvirt.org/sources/">libvirt.org HTTP server</a></li></ul>
<h2>Hourly development snapshots</h2>
<p>
Once an hour, an automated snapshot is made from the latest CVS server
source tree. These snapshots should be usable, but we make no guarantees
about their stability:
</p>
<ul><li><a href="ftp://libvirt.org/libvirt/libvirt-cvs-snapshot.tar.gz">libvirt.org FTP server</a></li><li><a href="http://libvirt.org/sources/libvirt-cvs-snapshot.tar.gz">libvirt.org HTTP server</a></li></ul>
<h2>CVS repository access</h2>
<p>
The master source repository uses <a href="http://ximbiot.com/cvs/cvshome/docs/">CVS</a>
and anonymous access is provided. Prior to accessing the server is it necessary
to authenticate using the password <code>anoncvs</code>. This can be accomplished with the
<code>cvs login</code> command:
</p>
<pre>
# cvs -d :pserver:anoncvs@libvirt.org:2401/data/cvs login
</pre>
<p>
Once authenticated, a checkout can be obtained using
</p>
<pre>
# cvs -d :pserver:anoncvs@libvirt.org:2401/data/cvs co libvirt
</pre>
<p>
The libvirt build process uses GNU autotools, so after obtaining a checkout
it is necessary to generate the configure script and Makefile.in templates
using the <code>autogen.sh</code> command. As an example, to do a complete
build and install it into your home directory run:
</p>
<pre>
./autogen.sh --prefix=$HOME/usr
make
make install
</pre>
<h2>GIT repository mirror</h2>
<p>
The CVS source repository is also mirrored using GIT, and is available
for anonymous access via:
</p>
<pre>
git clone git://git.et.redhat.com/libvirt.git
</pre>
<p>
It can also be browsed at
</p>

# cvs -d :pserver:anoncvs@libvirt.org:2401/data/cvs login
</pre>
<p>
Once authenticated, a checkout can be obtained using
</p>
<pre>
# cvs -d :pserver:anoncvs@libvirt.org:2401/data/cvs co libvirt
</pre>
<p>
The libvirt build process uses GNU autotools, so after obtaining a checkout
it is necessary to generate the configure script and Makefile.in templates
using the <code>autogen.sh</code> command. As an example, to do a complete
build and install it into your home directory run:
</p>
<pre>
./autogen.sh --prefix=$HOME/usr
make
make install
</pre>
<h2>GIT repository mirror</h2>
<p>
The CVS source repository is also mirrored using GIT, and is available
for anonymous access via:
</p>
<pre>
git clone git://git.et.redhat.com/libvirt.git
</pre>
<p>
It can also be browsed at
</p>
<pre>
<a href="http://git.et.redhat.com/?p=libvirt.git;a=summary">http://git.et.redhat.com/?p=libvirt.git;a=summary</a>

<h1>OpenVZ container driver</h1>
<p>
The OpenVZ driver for libvirt allows use and management of container
based virtualization on a Linux host OS. Prior to using the OpenVZ
driver, the OpenVZ enabled kernel must be installed &amp; booted, and the
OpenVZ userspace tools installed. The libvirt driver has been tested
with OpenVZ 3.0.22, but other 3.0.x versions should also work without
undue trouble.
</p>
<h2>Connections to OpenVZ driver</h2>
<p>
The libvirt OpenVZ driver is a single-instance privileged driver,
with a driver name of 'openvz'. Some example conection URIs for
the libvirt driver are:
</p>
<pre>
openvz:///system (local access)
openvz://example.com/system (remote access, TLS/x509)
openvz+tcp://example.com/system (remote access, SASl/Kerberos)
openvz+ssh://root@example.com/system (remote access, SSH tunnelled)
</pre>
<h2>Notes on bridged networking</h2>
<p>
Bridged networking enables a guest domain (ie container) to have its
network interface connected directly to the host's physical LAN. Before
this can be used there are a couple of configuration pre-requisites for
the host OS.
</p>
<h3>Host network devices</h3>
<p>
One or more of the physical devices must be attached to a bridge. The
process for this varies according to the operating system in use, so
for up to date notes consult the <a href="http://wiki.libvirt.org">Wiki</a>
or your operating system's networking documentation. The basic idea is
that the host OS should end up with a bridge device "br0" containing a
physical device "eth0", or a bonding device "bond0".
</p>
<h3>OpenVZ tools configuration</h3>
<p>
OpenVZ releases later than 3.0.23 ship with a standard network device
setup script that is able to setup bridging, named
<code>/usr/sbin/vznetaddbr</code>. For releases prior to 3.0.23, this
script must be created manually by the host OS adminstrator. The
simplest way is to just download the latest version of this script
from a newer OpenVZ release, or upstream source repository. Then
a generic configuration file <code>/etc/vz/vznetctl.conf</code>
must be created containing
</p>
<pre>
#!/bin/bash
EXTERNAL_SCRIPT="/usr/sbin/vznetaddbr"
</pre>
<p>
The host OS is now ready to allow bridging of guest containers, which
will work whether the container is started with libvirt, or OpenVZ
tools.
</p>
<h2>Example guest domain XML configuration</h2>
<p>
The current libvirt OpenVZ driver has a restriction that the
domain names must match the OpenVZ container VEID, which by
convention start at 100, and are incremented from there. The
choice of OS template to use inside the container is determined
by the <code>filesystem</code> tag, and the template source name
matches the templates known to OpenVZ tools.
</p>
<pre>
&lt;domain type='openvz' id='104'&gt;
&lt;name&gt;104&lt;/name&gt;
&lt;uuid&gt;86c12009-e591-a159-6e9f-91d18b85ef78&lt;/uuid&gt;
&lt;vcpu&gt;3&lt;/vcpu&gt;
&lt;os&gt;
&lt;type&gt;exe&lt;/type&gt;
&lt;init&gt;/sbin/init&lt;/init&gt;
&lt;/os&gt;

<h1>QEMU/KVM hypervisor driver</h1>
<p>
The libvirt QEMU driver can manage any QEMU emulator from version 0.8.1
or later. It can also manage anything that provides the same QEMU command
line syntax and monitor interaction. This includes KVM, and Xenner.
</p>
<h2>Deployment pre-requisites</h2>
<ul><li>
<strong>QEMU emulators</strong>: The driver will probe <code>/usr/bin</code>
for the presence of <code>qemu</code>, <code>qemu-system-x86_64</code>,
<code>qemu-system-mips</code>,<code>qemu-system-mipsel</code>,
<code>qemu-system-sparc</code>,<code>qemu-system-ppc</code>. The results
of this can be seen from the capabilities XML output.
</li><li>
<strong>KVM hypervisor</strong>: The driver will probe <code>/usr/bin</code>
for the presence of <code>qemu-kvm</code> and <code>/dev/kvm</code> device
node. If both are found, then KVM fullyvirtualized, hardware accelerated
guests will be available.
</li><li>
<strong>Xenner hypervisor</strong>: The driver will probe <code>/usr/bin</code>
for the presence of <code>xenner</code> and <code>/dev/kvm</code> device
node. If both are found, then Xen paravirtualized guests can be run using
the KVM hardware acceleration.

<h1>User Mode Linux driver</h1>
<p>
The UML driver for libvirt allows use and management of paravirtualized
guests built for User Mode Linux. UML requires no special support in
the host kernel, so can be used by any user of any linux system, provided
they have enough free RAM for their guest's needs, though there are
certain restrictions on network connectivity unless the adminstrator
has pre-created TAP devices.
</p>
<h2>Connections to UML driver</h2>
<p>
The libvirt UML driver follows the QEMU driver in providing two
types of connection. There is one privileged instance per host,
which runs as root. This is called the "system" instance, and allows
full use of all host resources. Then, there is a per-user unprivileged
"session", instance. This has more restricted capabilities, and may
require the host administrator to setup certain resources ahead of
time to allow full integration with the network. Example connection
URIs are
</p>
<pre>
uml:///system (local access, system instance)
uml:///session (local access, session instance)
uml://example.com/system (remote access, TLS/x509)
uml+tcp://example.com/system (remote access, SASl/Kerberos)
uml+ssh://root@example.com/system (remote access, SSH tunnelled)
</pre>
<h2>Example XML configuration</h2>
<p>
User mode Linux driver only supports directly kernel boot at
this time. A future driver enhancement may allow a paravirt
bootloader in a similar style to Xen's pygrub. For now though,
the UML kernel must be stored on the host and referenced
explicitly in the "os" element. Since UML is a paravirtualized
technology, the kernel "type" is set to "uml"
</p>
<p>
There is not yet support for networking in the driver, but
disks can be specified in the usual libvirt manner. The main
variation is the target device naming scheme "ubd0", and
bus type of "uml".
</p>
<p>
Once booted the primary console is connected toa PTY, and
thus accessible with "virsh console" or equivalent tools
</p>
<pre>
&lt;domain type='uml'&gt;
&lt;name&gt;demo&lt;/name&gt;

<h1>Xen hypervisor driver</h1>
<p>
The libvirt Xen driver provides the ability to manage virtual machines
on any Xen release from 3.0.1 onwards.
</p>
<h2>Deployment pre-requisites</h2>
<p>
The libvirt Xen driver uses a combination of channels to manage Xen
virtual machines.
</p>
<ul><li>
<strong>XenD</strong>: Access to the Xen daemon is a mandatory
requirement for the libvirt Xen driver. It requires that the UNIX
socket interface be enabled in the <code>/etc/xen/xend-config.sxp</code>
configuration file. Specifically the config settings
<code>(xend-unix-server yes)</code>. This path is usually restricted
to only allow the <code>root</code> user access. As an alternative,
the HTTP interface can be used, however, this has significant security
implications.
</li><li>
<strong>XenStoreD</strong>: Access to the Xenstore daemon enables
more efficient codepaths for looking up domain information which
lowers the CPU overhead of management.
</li><li>
<strong>Hypercalls</strong>: The ability to make direct hypercalls
allows the most efficient codepaths in the driver to be used for
monitoring domain status.
</li><li>
<strong>XM config</strong>: When using Xen releases prior to 3.0.4,
there is no inactive domain management in XenD. For such releases,
libvirt will automatically process XM configuration files kept in
the <code>/etc/xen</code> directory. It is important not to place
any other non-config files in this directory.
</li></ul>
<h2>
<a name="xmlconfig" id="xmlconfig">Example domain XML config</a>
</h2>
<p>
Below are some example XML configurations for Xen guest domains.
For full details of the available options, consult the <a href="formatdomain.html">domain XML format</a>
guide.
</p>
<h3>Paravirtualized guest bootloader</h3>
<p>
Using a bootloader allows a paravirtualized guest to be booted using
a kernel stored inside its virtual disk image
</p>
<pre>&lt;domain type='xen' &gt;
&lt;name&gt;fc8&lt;/name&gt;
&lt;bootloader&gt;/usr/bin/pygrub&lt;/bootloader&gt;
&lt;os&gt;
&lt;type&gt;linux&lt;/type&gt;
&lt;/os&gt;
&lt;memory&gt;131072&lt;/memory&gt;
&lt;vcpu&gt;1&lt;/vcpu&gt;
&lt;devices&gt;
&lt;disk type='file'&gt;
&lt;source file='/var/lib/xen/images/fc4.img'/&gt;
&lt;target dev='sda1'/&gt;
&lt;/disk&gt;
&lt;interface type='bridge'&gt;
&lt;source bridge='xenbr0'/&gt;
&lt;mac address='aa:00:00:00:00:11'/&gt;
&lt;script path='/etc/xen/scripts/vif-bridge'/&gt;
&lt;/interface&gt;
&lt;console tty='/dev/pts/5'/&gt;
&lt;/devices&gt;
&lt;/domain&gt;</pre>
<h3>Paravirtualized guest direct kernel boot</h3>
<p>
For installation of paravirtualized guests it is typical to boot the
domain using a kernel and initrd stored in the host OS
</p>
<pre>&lt;domain type='xen' &gt;
&lt;name&gt;fc8&lt;/name&gt;
&lt;os&gt;
&lt;type&gt;linux&lt;/type&gt;
&lt;kernel&gt;/var/lib/xen/install/vmlinuz-fedora8-x86_64&lt;/kernel&gt;
&lt;initrd&gt;/var/lib/xen/install/initrd-vmlinuz-fedora8-x86_64&lt;/initrd&gt;
&lt;cmdline&gt; kickstart=http://example.com/myguest.ks &lt;/cmdline&gt;
&lt;/os&gt;
&lt;memory&gt;131072&lt;/memory&gt;
&lt;vcpu&gt;1&lt;/vcpu&gt;
&lt;devices&gt;
&lt;disk type='file'&gt;
&lt;source file='/var/lib/xen/images/fc4.img'/&gt;
&lt;target dev='sda1'/&gt;
&lt;/disk&gt;
&lt;interface type='bridge'&gt;
&lt;source bridge='xenbr0'/&gt;
&lt;mac address='aa:00:00:00:00:11'/&gt;
&lt;script path='/etc/xen/scripts/vif-bridge'/&gt;
&lt;/interface&gt;
&lt;graphics type='vnc' port='-1'/&gt;
&lt;console tty='/dev/pts/5'/&gt;
&lt;/devices&gt;
&lt;/domain&gt;</pre>
<h3>Fullyvirtualized guest BIOS boot</h3>
<p>
Fullyvirtualized guests use the emulated BIOS to boot off the primary
harddisk, CDROM or Network PXE ROM.
</p>
<pre>&lt;domain type='xen' id='3'&gt;
&lt;name&gt;fv0&lt;/name&gt;
&lt;uuid&gt;4dea22b31d52d8f32516782e98ab3fa0&lt;/uuid&gt;
&lt;os&gt;
&lt;type&gt;hvm&lt;/type&gt;
&lt;loader&gt;/usr/lib/xen/boot/hvmloader&lt;/loader&gt;
&lt;boot dev='hd'/&gt;
&lt;/os&gt;
&lt;memory&gt;524288&lt;/memory&gt;
&lt;vcpu&gt;1&lt;/vcpu&gt;
&lt;on_poweroff&gt;destroy&lt;/on_poweroff&gt;
&lt;on_reboot&gt;restart&lt;/on_reboot&gt;
&lt;on_crash&gt;restart&lt;/on_crash&gt;
&lt;features&gt;
&lt;pae/&gt;
&lt;acpi/&gt;
&lt;apic/&gt;
&lt;/features&gt;
&lt;clock sync="localtime"/&gt;
&lt;devices&gt;
&lt;emulator&gt;/usr/lib/xen/bin/qemu-dm&lt;/emulator&gt;
&lt;interface type='bridge'&gt;
&lt;source bridge='xenbr0'/&gt;
&lt;mac address='00:16:3e:5d:c7:9e'/&gt;
&lt;script path='vif-bridge'/&gt;
&lt;/interface&gt;
&lt;disk type='file'&gt;
&lt;source file='/var/lib/xen/images/fv0'/&gt;
&lt;target dev='hda'/&gt;
&lt;/disk&gt;
&lt;disk type='file' device='cdrom'&gt;
&lt;source file='/var/lib/xen/images/fc5-x86_64-boot.iso'/&gt;
&lt;target dev='hdc'/&gt;
&lt;readonly/&gt;
&lt;/disk&gt;
&lt;disk type='file' device='floppy'&gt;
&lt;source file='/root/fd.img'/&gt;
&lt;target dev='fda'/&gt;
&lt;/disk&gt;
&lt;graphics type='vnc' port='5904'/&gt;
&lt;/devices&gt;
&lt;/domain&gt;</pre>
<h3>Fullyvirtualized guest direct kernel boot</h3>
<p>
With Xen 3.2.0 or later it is possible to bypass the BIOS and directly
boot a Linux kernel and initrd as a fullyvirtualized domain. This allows
for complete automation of OS installation, for example using the Anaconda
kickstart support.
</p>
<pre>&lt;domain type='xen' id='3'&gt;
&lt;name&gt;fv0&lt;/name&gt;
&lt;uuid&gt;4dea22b31d52d8f32516782e98ab3fa0&lt;/uuid&gt;
&lt;os&gt;
&lt;type&gt;hvm&lt;/type&gt;
&lt;loader&gt;/usr/lib/xen/boot/hvmloader&lt;/loader&gt;
&lt;kernel&gt;/var/lib/xen/install/vmlinuz-fedora8-x86_64&lt;/kernel&gt;
&lt;initrd&gt;/var/lib/xen/install/initrd-vmlinuz-fedora8-x86_64&lt;/initrd&gt;
&lt;cmdline&gt; kickstart=http://example.com/myguest.ks &lt;/cmdline&gt;
&lt;/os&gt;
&lt;memory&gt;524288&lt;/memory&gt;
&lt;vcpu&gt;1&lt;/vcpu&gt;
&lt;on_poweroff&gt;destroy&lt;/on_poweroff&gt;
&lt;on_reboot&gt;restart&lt;/on_reboot&gt;
&lt;on_crash&gt;restart&lt;/on_crash&gt;
&lt;features&gt;
&lt;pae/&gt;
&lt;acpi/&gt;
&lt;apic/&gt;
&lt;/features&gt;
&lt;clock sync="localtime"/&gt;
&lt;devices&gt;

<h3>Paravirtualized guest direct kernel boot</h3>
<p>
For installation of paravirtualized guests it is typical to boot the
domain using a kernel and initrd stored in the host OS
</p>
<pre>&lt;domain type='xen' &gt;
&lt;name&gt;fc8&lt;/name&gt;
&lt;os&gt;
&lt;type&gt;linux&lt;/type&gt;
&lt;kernel&gt;/var/lib/xen/install/vmlinuz-fedora8-x86_64&lt;/kernel&gt;
&lt;initrd&gt;/var/lib/xen/install/initrd-vmlinuz-fedora8-x86_64&lt;/initrd&gt;
&lt;cmdline&gt; kickstart=http://example.com/myguest.ks &lt;/cmdline&gt;
&lt;/os&gt;
&lt;memory&gt;131072&lt;/memory&gt;
&lt;vcpu&gt;1&lt;/vcpu&gt;
&lt;devices&gt;
&lt;disk type='file'&gt;
&lt;source file='/var/lib/xen/images/fc4.img'/&gt;
&lt;target dev='sda1'/&gt;
&lt;/disk&gt;
&lt;interface type='bridge'&gt;
&lt;source bridge='xenbr0'/&gt;
&lt;mac address='aa:00:00:00:00:11'/&gt;
&lt;script path='/etc/xen/scripts/vif-bridge'/&gt;
&lt;/interface&gt;
&lt;graphics type='vnc' port='-1'/&gt;
&lt;console tty='/dev/pts/5'/&gt;
&lt;/devices&gt;
&lt;/domain&gt;</pre>
<h3>Fullyvirtualized guest BIOS boot</h3>
<p>
Fullyvirtualized guests use the emulated BIOS to boot off the primary
harddisk, CDROM or Network PXE ROM.
</p>
<pre>&lt;domain type='xen' id='3'&gt;
&lt;name&gt;fv0&lt;/name&gt;
&lt;uuid&gt;4dea22b31d52d8f32516782e98ab3fa0&lt;/uuid&gt;

&lt;acpi/&gt;
&lt;apic/&gt;
&lt;/features&gt;
&lt;clock sync="localtime"/&gt;
&lt;devices&gt;

&lt;interface type='bridge'&gt;
&lt;source bridge='xenbr0'/&gt;
&lt;mac address='00:16:3e:5d:c7:9e'/&gt;

&lt;target dev='fda'/&gt;
&lt;/disk&gt;
&lt;graphics type='vnc' port='5904'/&gt;
&lt;/devices&gt;
&lt;/domain&gt;</pre>
<h3>Fullyvirtualized guest direct kernel boot</h3>
<p>
With Xen 3.2.0 or later it is possible to bypass the BIOS and directly
boot a Linux kernel and initrd as a fullyvirtualized domain. This allows
for complete automation of OS installation, for example using the Anaconda
kickstart support.
</p>
<pre>&lt;domain type='xen' id='3'&gt;
&lt;name&gt;fv0&lt;/name&gt;

&lt;loader&gt;/usr/lib/xen/boot/hvmloader&lt;/loader&gt;
&lt;kernel&gt;/var/lib/xen/install/vmlinuz-fedora8-x86_64&lt;/kernel&gt;
&lt;initrd&gt;/var/lib/xen/install/initrd-vmlinuz-fedora8-x86_64&lt;/initrd&gt;

<p>As result the library provide both synchronous, callback based and

error callback it will be called synchronously. Once the call to libvirt ends

&lt;/devices&gt;
&lt;/domain&gt;</pre><p>The root element must be called <code>domain</code> with no namespace, the
<code>type</code> attribute indicates the kind of hypervisor used, 'xen' is
the default value. The <code>id</code> attribute gives the domain id at
runtime (not however that this may change, for example if the domain is saved
to disk and restored). The domain has a few children whose order is not
significant:</p><ul><li>name: the domain name, preferably ASCII based</li>
<li>memory: the maximum memory allocated to the domain in kilobytes</li>
<li>vcpu: the number of virtual cpu configured for the domain</li>
<li>os: a block describing the Operating System, its content will be
dependent on the OS type
<ul><li>type: indicate the OS type, always linux at this point</li>
<li>kernel: path to the kernel on the Domain 0 filesystem</li>
<li>initrd: an optional path for the init ramdisk on the Domain 0
filesystem</li>
<li>cmdline: optional command line to the kernel</li>
<li>root: the root filesystem from the guest viewpoint, it may be
passed as part of the cmdline content too</li>
</ul></li>
<li>devices: a list of <code>disk</code>, <code>interface</code> and
<code>console</code> descriptions in no special order</li>
</ul><p>The format of the devices and their type may grow over time, but the
following should be sufficient for basic use:</p><p>A <code>disk</code> device indicates a block device, it can have two
values for the type attribute either 'file' or 'block' corresponding to the 2
options available at the Xen layer. It has two mandatory children, and one
optional one in no specific order:</p><ul><li>source with a file attribute containing the path in Domain 0 to the
file or a dev attribute if using a block device, containing the device
name ('hda5' or '/dev/hda5')</li>
<li>target indicates in a dev attribute the device where it is mapped in
the guest</li>
<li>readonly an optional empty element indicating the device is
read-only</li>
<li>shareable an optional empty element indicating the device
can be used read/write with other domains</li>
</ul><p>An <code>interface</code> element describes a network device mapped on the
guest, it also has a type whose value is currently 'bridge', it also have a
number of children in no specific order:</p><ul><li>source: indicating the bridge name</li>
<li>mac: the optional mac address provided in the address attribute</li>
<li>ip: the optional IP address provided in the address attribute</li>
<li>script: the script used to bridge the interface in the Domain 0</li>
<li>target: and optional target indicating the device name.</li>
</ul><p>A <code>console</code> element describes a serial console connection to
the guest. It has no children, and a single attribute <code>tty</code> which
provides the path to the Pseudo TTY on which the guest console can be
accessed</p><p>Life cycle actions for the domain can also be expressed in the XML format,
they drive what should be happening if the domain crashes, is rebooted or is
poweroff. There is various actions possible when this happen:</p><ul><li>destroy: The domain is cleaned up (that's the default normal processing
in Xen)</li>
<li>restart: A new domain is started in place of the old one with the same
configuration parameters</li>
<li>preserve: The domain will remain in memory until it is destroyed
manually, it won't be running but allows for post-mortem debugging</li>
<li>rename-restart: a variant of the previous one but where the old domain
is renamed before being saved to allow a restart</li>
</ul><p>The following could be used for a Xen production system:</p><pre>&lt;domain&gt;
...
&lt;on_reboot&gt;restart&lt;/on_reboot&gt;
&lt;on_poweroff&gt;destroy&lt;/on_poweroff&gt;
&lt;on_crash&gt;rename-restart&lt;/on_crash&gt;
...
&lt;/domain&gt;</pre><p>While the format may be extended in various ways as support for more
hypervisor types and features are added, it is expected that this core subset
will remain functional in spite of the evolution of the library.</p><h3 id="Fully"><a name="Fully1" id="Fully1">Fully virtualized guests</a>

virtualized (a.k.a. HVM) Xen domain. This requires hardware virtualization
support at the processor level but allows to run unmodified operating
systems:</p><pre>&lt;domain type='xen' id='3'&gt;

<span style="color: #0000E5; background-color: #FFFFFF">&lt;graphics type='vnc' port='5904'/&gt;</span>
&lt;/devices&gt;
&lt;/domain&gt;</pre><p>There is a few things to notice specifically for HVM domains:</p><ul><li>the optional <code>&lt;features&gt;</code> block is used to enable
certain guest CPU / system features. For HVM guests the following
features are defined:
<ul><li><code>pae</code> - enable PAE memory addressing</li>
<li><code>apic</code> - enable IO APIC</li>
<li><code>acpi</code> - enable ACPI bios</li>
</ul></li>
<li>the optional <code>&lt;clock&gt;</code> element is used to specify
whether the emulated BIOS clock in the guest is synced to either
<code>localtime</code> or <code>utc</code>. In general Windows will
want <code>localtime</code> while all other operating systems will
want <code>utc</code>. The default is thus <code>utc</code></li>
<li>the <code>&lt;os&gt;</code> block description is very different, first
it indicates that the type is 'hvm' for hardware virtualization, then
instead of a kernel, boot and command line arguments, it points to an os
boot loader which will extract the boot information from the boot device
specified in a separate boot element. The <code>dev</code> attribute on
the <code>boot</code> tag can be one of:
<ul><li><code>fd</code> - boot from first floppy device</li>
<li><code>hd</code> - boot from first harddisk device</li>
<li><code>cdrom</code> - boot from first cdrom device</li>
</ul></li>
<li>the <code>&lt;devices&gt;</code> section includes an emulator entry
pointing to an additional program in charge of emulating the devices</li>
<li>the disk entry indicates in the dev target section that the emulation
for the drive is the first IDE disk device hda. The list of device names
supported is dependent on the Hypervisor, but for Xen it can be any IDE
device <code>hda</code>-<code>hdd</code>, or a floppy device
<code>fda</code>, <code>fdb</code>. The <code>&lt;disk&gt;</code> element
also supports a 'device' attribute to indicate what kinda of hardware to
emulate. The following values are supported:
<ul><li><code>floppy</code> - a floppy disk controller</li>
<li><code>disk</code> - a generic hard drive (the default it
omitted)</li>
<li><code>cdrom</code> - a CDROM device</li>
</ul>
For Xen 3.0.2 and earlier a CDROM device can only be emulated on the
<code>hdc</code> channel, while for 3.0.3 and later, it can be emulated
on any IDE channel.</li>
<li>the <code>&lt;devices&gt;</code> section also include at least one
entry for the graphic device used to render the os. Currently there is
just 2 types possible 'vnc' or 'sdl'. If the type is 'vnc', then an
additional <code>port</code> attribute will be present indicating the TCP
port on which the VNC server is accepting client connections.</li>
</ul><p>It is likely that the HVM description gets additional optional elements
and attributes as the support for fully virtualized domain expands,
especially for the variety of devices emulated and the graphic support
options offered.</p><h3><a name="KVM1" id="KVM1">KVM domain (added in 0.2.0)</a></h3><p>Support for the <a href="http://kvm.qumranet.com/">KVM virtualization</a>
is provided in recent Linux kernels (2.6.20 and onward). This requires
specific hardware with acceleration support and the availability of the
special version of the <a href="http://fabrice.bellard.free.fr/qemu/">QEmu</a> binary. Since this
relies on QEmu for the machine emulation like fully virtualized guests the
XML description is quite similar, here is a simple example:</p><pre>&lt;domain <span style="color: #FF0000; background-color: #FFFFFF">type='kvm'</span>&gt;
&lt;name&gt;demo2&lt;/name&gt;
&lt;uuid&gt;4dea24b3-1d52-d8f3-2516-782e98a23fa0&lt;/uuid&gt;
&lt;memory&gt;131072&lt;/memory&gt;
&lt;vcpu&gt;1&lt;/vcpu&gt;
&lt;os&gt;
&lt;type&gt;hvm&lt;/type&gt;
&lt;/os&gt;
<span style="color: #0000E5; background-color: #FFFFFF">&lt;clock sync="localtime"/&gt;</span>
&lt;devices&gt;
<span style="color: #FF0000; background-color: #FFFFFF">&lt;emulator&gt;/home/user/usr/kvm-devel/bin/qemu-system-x86_64&lt;/emulator&gt;</span>
&lt;disk type='file' device='disk'&gt;
&lt;source file='/home/user/fedora/diskboot.img'/&gt;
&lt;target dev='hda'/&gt;
&lt;/disk&gt;
&lt;interface <span style="color: #FF0000; background-color: #FFFFFF">type='user'</span>&gt;
&lt;mac address='24:42:53:21:52:45'/&gt;
&lt;/interface&gt;
&lt;graphics type='vnc' port='-1'/&gt;
&lt;/devices&gt;
&lt;/domain&gt;</pre><p>The specific points to note if using KVM are:</p><ul><li>the top level domain element carries a type of 'kvm'</li>
<li>the &lt;clock&gt; optional is supported as with Xen HVM</li>
<li>the &lt;devices&gt; emulator points to the special qemu binary required
for KVM</li>
<li>networking interface definitions definitions are somewhat different due
to a different model from Xen see below</li>
</ul><p>except those points the options should be quite similar to Xen HVM
ones.</p><h3><a name="Net1" id="Net1">Networking options for QEmu and KVM (added in 0.2.0)</a></h3><p>The networking support in the QEmu and KVM case is more flexible, and
support a variety of options:</p><ol><li>Userspace SLIRP stack
<p>Provides a virtual LAN with NAT to the outside world. The virtual
network has DHCP &amp; DNS services and will give the guest VM addresses
starting from <code>10.0.2.15</code>. The default router will be
<code>10.0.2.2</code> and the DNS server will be <code>10.0.2.3</code>.
This networking is the only option for unprivileged users who need their
VMs to have outgoing access. Example configs are:</p>
<pre>&lt;interface type='user'/&gt;</pre>
<pre>
&lt;interface type='user'&gt;
&lt;mac address="11:22:33:44:55:66"/&gt;
&lt;/interface&gt;
</pre>
</li>
<li>Virtual network
<p>Provides a virtual network using a bridge device in the host.
Depending on the virtual network configuration, the network may be
totally isolated, NAT'ing to an explicit network device, or NAT'ing to
the default route. DHCP and DNS are provided on the virtual network in
all cases and the IP range can be determined by examining the virtual
network config with '<code>virsh net-dumpxml &lt;network
name&gt;</code>'. There is one virtual network called 'default' setup out
of the box which does NAT'ing to the default route and has an IP range of
<code>192.168.22.0/255.255.255.0</code>. Each guest will have an
associated tun device created with a name of vnetN, which can also be
overridden with the &lt;target&gt; element. Example configs are:</p>
<pre>&lt;interface type='network'&gt;
&lt;source network='default'/&gt;
&lt;/interface&gt;
&lt;interface type='network'&gt;
&lt;source network='default'/&gt;
&lt;target dev='vnet7'/&gt;
&lt;mac address="11:22:33:44:55:66"/&gt;
&lt;/interface&gt;
</pre>
</li>
<li>Bridge to to LAN
<p>Provides a bridge from the VM directly onto the LAN. This assumes
there is a bridge device on the host which has one or more of the hosts
physical NICs enslaved. The guest VM will have an associated tun device
created with a name of vnetN, which can also be overridden with the
&lt;target&gt; element. The tun device will be enslaved to the bridge.
The IP range / network configuration is whatever is used on the LAN. This
provides the guest VM full incoming &amp; outgoing net access just like a
physical machine. Examples include:</p>
<pre>&lt;interface type='bridge'&gt;
&lt;source bridge='br0'/&gt;
&lt;/interface&gt;
&lt;interface type='bridge'&gt;
&lt;source bridge='br0'/&gt;
&lt;target dev='vnet7'/&gt;
&lt;mac address="11:22:33:44:55:66"/&gt;
&lt;/interface&gt;</pre>
</li>
<li>Generic connection to LAN
<p>Provides a means for the administrator to execute an arbitrary script
to connect the guest's network to the LAN. The guest will have a tun
device created with a name of vnetN, which can also be overridden with the
&lt;target&gt; element. After creating the tun device a shell script will
be run which is expected to do whatever host network integration is
required. By default this script is called /etc/qemu-ifup but can be
overridden.</p>
<pre>&lt;interface type='ethernet'/&gt;
&lt;interface type='ethernet'&gt;
&lt;target dev='vnet7'/&gt;
&lt;script path='/etc/qemu-ifup-mynet'/&gt;
&lt;/interface&gt;</pre>
</li>
<li>Multicast tunnel
<p>A multicast group is setup to represent a virtual network. Any VMs
whose network devices are in the same multicast group can talk to each
other even across hosts. This mode is also available to unprivileged
users. There is no default DNS or DHCP support and no outgoing network
access. To provide outgoing network access, one of the VMs should have a
2nd NIC which is connected to one of the first 4 network types and do the
appropriate routing. The multicast protocol is compatible with that used
by user mode linux guests too. The source address used must be from the
multicast address block.</p>
<pre>&lt;interface type='mcast'&gt;
&lt;source address='230.0.0.1' port='5558'/&gt;
&lt;/interface&gt;</pre>
</li>
<li>TCP tunnel
<p>A TCP client/server architecture provides a virtual network. One VM
provides the server end of the network, all other VMS are configured as
clients. All network traffic is routed between the VMs via the server.
This mode is also available to unprivileged users. There is no default
DNS or DHCP support and no outgoing network access. To provide outgoing
network access, one of the VMs should have a 2nd NIC which is connected
to one of the first 4 network types and do the appropriate routing.</p>
<p>Example server config:</p>
<pre>&lt;interface type='server'&gt;
&lt;source address='192.168.0.1' port='5558'/&gt;
&lt;/interface&gt;</pre>

This section describes the XML format used to represent domains, there are
variations on the format based on the kind of domains run and the options
used to launch them. For hypervisor specific details consult the
<a href="drivers.html">driver docs</a>
</p>
<h2>
<a name="elements" id="elements">Element and attribute overview</a>
</h2>
<p>
The root element required for all virtual machines is
named <code>domain</code>. It has two attributes, the
<code>type</code> specifies the hypervisor used for running
the domain. The allowed values are driver specific, but
include "xen", "kvm", "qemu", "lxc" and "kqemu". The
second attribute is <code>id</code> which is a unique
integer identifier for the running guest machine. Inactive
machines have no id value.
</p>
<h3>
<a name="elementsMetadata" id="elementsMetadata">General metadata</a>
</h3>
<pre>
&lt;domain type='xen' id='3'&gt;
&lt;name&gt;fv0&lt;/name&gt;
&lt;uuid&gt;4dea22b31d52d8f32516782e98ab3fa0&lt;/uuid&gt;
...</pre>
<dl><dt><code>name</code></dt><dd>The content of the <code>name</code> element provides
a short name for the virtual machine. This name should
consist only of alpha-numeric characters and is required
to be unique within the scope of a single host. It is
often used to form the filename for storing the persistent
configuration file. <span class="since">Since 0.0.1</span></dd><dt><code>uuid</code></dt><dd>The content of the <code>uuid</code> element provides
a globally unique identifier for the virtual machine.
The format must be RFC 4122 compliant, eg <code>3e3fce45-4f53-4fa7-bb32-11f34168b82b</code>.
If omitted when defining/creating a new machine, a random
UUID is generated. <span class="since">Since 0.0.1</span></dd></dl>
<h3>
<a name="elementsOS" id="elementsOS">Operating system booting</a>
</h3>
<p>
There are a number of different ways to boot virtual machines
each with their own pros and cons.
</p>
<h4>
<a name="elementsOSBIOS" id="elementsOSBIOS">BIOS bootloader</a>
</h4>
<p>
Booting via the BIOS is available for hypervisors supporting
full virtualization. In this case the BIOS has a boot order
priority (floppy, harddisk, cdrom, network) determining where
to obtain/find the boot image.
</p>
<pre>
...
&lt;os&gt;
&lt;type&gt;hvm&lt;/type&gt;
&lt;loader&gt;/usr/lib/xen/boot/hvmloader&lt;/loader&gt;
&lt;boot dev='hd'/&gt;
&lt;/os&gt;
...</pre>
<dl><dt><code>type</code></dt><dd>The content of the <code>type</code> element specifies the
type of operating system to be booted in the virtual machine.
<code>hvm</code> indicates that the OS is one designed to run
on bare metal, so requires full virtualization. <code>linux</code>
(badly named!) refers to an OS that supports the Xen 3 hypervisor
guest ABI. There are also two optional attributes, <code>arch</code>
specifying the CPU architecture to virtualization, and <code>machine</code>
referring to the machine type. The <a href="formatcaps.html">Capabilities XML</a>
provides details on allowed values for these. <span class="since">Since 0.0.1</span></dd><dt><code>loader</code></dt><dd>The optional <code>loader</code> tag refers to a firmware blob
used to assist the domain creation process. At this time, it is
only needed by Xen fully virtualized domains. <span class="since">Since 0.1.0</span></dd><dt><code>boot</code></dt><dd>The <code>dev</code> attribute takes one of the values "fd", "hd",
"cdrom" or "network" and is used to specify the next boot device
to consider. The <code>boot</code> element can be repeated multiple
times to setup a priority list of boot devices to try in turn.
<span class="since">Since 0.1.3</span>
</dd></dl>
<h4>
<a name="elementsOSBootloader" id="elementsOSBootloader">Host bootloader</a>
</h4>
<p>
Hypervisors employing paravirtualization do not usually emulate
a BIOS, and instead the host is responsible to kicking off the
operating system boot. This may use a pseudo-bootloader in the
host to provide an interface to choose a kernel for the guest.
An example is <code>pygrub</code> with Xen.
</p>
<pre>
...
&lt;bootloader&gt;/usr/bin/pygrub&lt;/bootloader&gt;
&lt;bootloader_args&gt;--append single&lt;/bootloader_args&gt;
...</pre>
<dl><dt><code>bootloader</code></dt><dd>The content of the <code>bootloader</code> element provides
a fully qualified path to the bootloader executable in the
host OS. This bootloader will be run to choose which kernel
to boot. The required output of the bootloader is dependent
on the hypervisor in use. <span class="since">Since 0.1.0</span></dd><dt><code>bootloader_args</code></dt><dd>The optional <code>bootloader_args</code> element allows
command line arguments to be passed to the bootloader.
<span class="since">Since 0.2.3</span>
</dd></dl>
<h4>
<a name="elementsOSKernel" id="elementsOSKernel">Direct kernel boot</a>
</h4>
<p>
When installing a new guest OS it is often useful to boot directly
from a kernel and initrd stored in the host OS, allowing command
line arguments to be passed directly to the installer. This capability
is usually available for both para and full virtualized guests.
</p>
<pre>
...
&lt;os&gt;
&lt;type&gt;hvm&lt;/type&gt;
&lt;loader&gt;/usr/lib/xen/boot/hvmloader&lt;/loader&gt;
&lt;kernel&gt;/root/f8-i386-vmlinuz&lt;/kernel&gt;
&lt;initrd&gt;/root/f8-i386-initrd&lt;/initrd&gt;
&lt;cmdline&gt;console=ttyS0 ks=http://example.com/f8-i386/os/&lt;/cmdline&gt;
&lt;/os&gt;
...</pre>
<dl><dt><code>type</code></dt><dd>This element has the same semantics as described earlier in the
<a href="#elementsOSBIOS">BIOS boot section</a></dd><dt><code>loader</code></dt><dd>This element has the same semantics as described earlier in the
<a href="#elementsOSBIOS">BIOS boot section</a></dd><dt><code>kernel</code></dt><dd>The contents of this element specify the fully-qualified path
to the kernel image in the host OS.</dd><dt><code>initrd</code></dt><dd>The contents of this element specify the fully-qualified path
to the (optional) ramdisk image in the host OS.</dd><dt><code>cmdline</code></dt><dd>The contents of this element specify arguments to be passed to
the kernel (or installer) at boottime. This is often used to
specify an alternate primary console (eg serial port), or the
installation media source / kickstart file</dd></dl>
<h3>
<a name="elementsResources" id="elementsResources">Basic resources</a>
</h3>
<pre>
...
&lt;memory&gt;524288&lt;/memory&gt;
&lt;currentMemory&gt;524288&lt;/currentMemory&gt;
&lt;vcpu&gt;1&lt;/vcpu&gt;
...</pre>
<dl><dt><code>memory</code></dt><dd>The maximum allocation of memory for the guest at boot time.
The units for this value are kilobytes (i.e. blocks of 1024 bytes)</dd><dt><code>currentMemory</code></dt><dd>The actual allocation of memory for the guest. This value
be less than the maximum allocation, to allow for ballooning
up the guests memory on the fly. If this is omitted, it defaults
to the same value as the <code>memory<code> element</code></code></dd><dt><code>vcpu</code></dt><dd>The content of this element defines the number of virtual
CPUs allocated for the guest OS.</dd></dl>
<h3>
<a name="elementsLifecycle" id="elementsLifecycle">Lifecycle control</a>
</h3>
<p>
It is sometimes necessary to override the default actions taken
when a guest OS triggers a lifecycle operation. The following
collections of elements allow the actions to be specified. A
common use case is to force a reboot to be treated as a poweroff
when doing the initial OS installation. This allows the VM to be
re-configured for the first post-install bootup.
</p>
<pre>
...
&lt;on_poweroff&gt;destroy&lt;/on_poweroff&gt;
&lt;on_reboot&gt;restart&lt;/on_reboot&gt;
&lt;on_crash&gt;restart&lt;/on_crash&gt;
...</pre>
<dl><dt><code>on_poweroff</code></dt><dd>The content of this element specifies the action to take when
the guest requests a poweroff.</dd><dt><code>on_reboot</code></dt><dd>The content of this element specifies the action to take when
the guest requests a reboot.</dd><dt><code>on_crash</code></dt><dd>The content of this element specifies the action to take when
the guest crashes.</dd></dl>
<p>
Each of these states allow for the same four possible actions.
</p>
<dl><dt><code>destroy</code></dt><dd>The domain will be terminated completely and all resources
released</dd><dt><code>restart</code></dt><dd>The domain will be terminated, and then restarted with
the same configuration</dd><dt><code>preserve</code></dt><dd>The domain will be terminated, and its resource preserved
to allow analysis.</dd><dt><code>rename-restart</code></dt><dd>The domain will be terminated, and then restarted with
a new name</dd></dl>
<h3>
<a name="elementsFeatures" id="elementsFeatures">Hypervisor features</a>
</h3>
<p>
Hypervisors may allow certain CPU / machine features to be
toggled on/off.
</p>
<pre>
...
&lt;features&gt;
&lt;pae/&gt;
&lt;acpi/&gt;
&lt;apic/&gt;
&lt;/features&gt;
...</pre>
<p>
All features are listed within the <code>features</code>
element, omitting a togglable feature tag turns it off.
The available features can be found by asking
for the <a href="formatcaps.html">capabilities XML</a>,
but a common set for fully virtualized domains are:
</p>
<dl><dt><code>pae</code></dt><dd>Physical address extension mode allows 32-bit guests
to address more than 4 GB of memory.</dd><dt><code>acpi</code></dt><dd>ACPI is useful for power management, for example, with
KVM guests it is required for graceful shutdown to work.
</dd></dl>
<h3>
<a name="elementsTime" id="elementsTime">Time keeping</a>
</h3>
<p>
The guest clock is typically initialized from the host clock.
Most operating systems expect the hardware clock to be kept
in UTC, and this is the default. Windows, however, expects
it to be in so called 'localtime'.
</p>
<pre>
...
&lt;clock sync="localtime"/&gt;
...</pre>
<dl><dt><code>clock</code></dt><dd>The <code>sync</code> attribute takes either "utc" or
"localtime" to specify how the guest clock is initialized
in relation to the host OS.
</dd></dl>
<h3>
<a name="elementsDevices" id="elementsDevices">Devices</a>
</h3>
<p>
The final set of XML elements are all used to describe devices
provided to the guest domain. All devices occur as children
of the main <code>devices</code> element.
<span class="since">Since 0.1.3</span>
</p>
<pre>
...
&lt;devices&gt;
&lt;emulator&gt;/usr/lib/xen/bin/qemu-dm&lt;/emulator&gt;
...</pre>
<dl><dt><code>emulator</code></dt><dd>
The contents of the <code>emulator</code> element specify
the fully qualified path to the device model emulator binary.
The <a href="formatcaps.html">capabilities XML</a> specifies
the recommended default emulator to use for each particular
domain type / architecture combination.
</dd></dl>
<h4>
<a name="elementsDisks" id="elementsDisks">Hard drives, floppy disks, CDROMs</a>
</h4>
<p>
Any device that looks like a disk, be it a floppy, harddisk,
cdrom, or paravirtualized driver is specified via the <code>disk</code>
element.
</p>
<pre>
...
&lt;disk type='file'&gt;
&lt;driver name="tap" type="aio"&gt;
&lt;source file='/var/lib/xen/images/fv0'/&gt;
&lt;target dev='hda' bus='ide'/&gt;
&lt;/disk&gt;
...</pre>
<dl><dt><code>disk</code></dt><dd>The <code>disk</code> element is the main container for describing
disks. The <code>type</code> attribute is either "file" or "block"
and refers to the underlying source for the disk. The optional
<code>device</code> attribute indicates how the disk is to be exposed
to the guest OS. Possible values for this attribute are "floppy", "disk"
and "cdrom", defaulting to "disk".
<span class="since">Since 0.0.3; "device" attribute since 0.1.4</span></dd><dt><code>source</code></dt><dd>If the disk <code>type</code> is "file", then the <code>file</code> attribute
specifies the fully-qualified path to the file holding the disk. If the disk
<code>type</code> is "block", then the <code>dev</code> attribute specifies
the path to the host device to serve as the disk. <span class="since">Since 0.0.3</span></dd><dt><code>target</code></dt><dd>The <code>target</code> element controls the bus / device under which the
disk is exposed to the guest OS. The <code>dev</code> attribute indicates
the "logical" device name. The actual device name specified is not guaranteed to map to
the device name in the guest OS. Treat it as a device ordering hint.
The optional <code>bus</code> attribute specifies the type of disk device
to emulate; possible values are driver specific, with typical values being
"ide", "scsi", "virtio", "xen" or "usb". If omitted, the bus type is
inferred from the style of the device name. eg, a device named 'sda'
will typically be exported using a SCSI bus.
<span class="since">Since 0.0.3; <code>bus</code> attribute since 0.4.3;
"usb" attribute value since after 0.4.4</span></dd><dt><code>driver</code></dt><dd>If the hypervisor supports multiple backend drivers, then the optional
<code>driver</code> element allows them to be selected. The <code>name</code>
attribute is the primary backend driver name, while the optional <code>type</code>
attribute provides the sub-type. <span class="since">Since 0.1.8</span>
</dd></dl>
<h4>
<a name="elementsUSB" id="elementsUSB">USB devices</a>
</h4>
<p>
USB devices attached to the host can be passed through to the guest using
the <code>hostdev</code> element. <span class="since">since after 0.4.4</span>
</p>
<pre>

&lt;hostdev mode='subsystem' type='usb'&gt;
&lt;source&gt;
&lt;vendor id='0x1234'/&gt;
&lt;product id='0xbeef'/&gt;
&lt;/source&gt;
&lt;/disk&gt;
...</pre>
<dl><dt><code>hostdev</code></dt><dd>The <code>hostdev</code> element is the main container for describing
host devices. For usb device passthrough <code>mode</code> is always
"subsystem" and <code>type</code> is "usb".
</dd><dt><code>source</code></dt><dd>The source element describes the device as seen from the host.
The USB device can either be addressed by vendor / product id using the
<code>vendor</code> and <code>product</code> elements or by the device's
address on the hosts using the <code>address</code> element.</dd><dt><code>vendor</code>, <code>product</code></dt><dd>The <code>vendor</code> and <code>product</code> elements each have an
<code>id</code> attribute that specifies the USB vendor and product id.
The ids can be given in decimal, hexadecimal (starting with 0x) or
octal (starting with 0) form.</dd><dt><code>address</code></dt><dd>The <code>address</code> element has a <code>bus</code> and
<code>device</code> attribute to specify the USB bus and device number
the device appears at on the host. The values of these attributes can

</h5>
<p>
<strong><em>
This is the recommended config for general guest connectivity on
hosts with dynamic / wireless networking configs
</em></strong>
</p>
<p>
Provides a virtual network using a bridge device in the host.
Depending on the virtual network configuration, the network may be
totally isolated, NAT'ing to an explicit network device, or NAT'ing to
the default route. DHCP and DNS are provided on the virtual network in
all cases and the IP range can be determined by examining the virtual
network config with '<code>virsh net-dumpxml [networkname]</code>'.
There is one virtual network called 'default' setup out
of the box which does NAT'ing to the default route and has an IP range of
<code>192.168.22.0/255.255.255.0</code>. Each guest will have an
associated tun device created with a name of vnetN, which can also be
overridden with the &lt;target&gt; element.

</h5>
<p>
<strong><em>
This is the recommended config for general guest connectivity on

</em></strong>
</p>
<p>
Provides a bridge from the VM directly onto the LAN. This assumes
there is a bridge device on the host which has one or more of the hosts
physical NICs enslaved. The guest VM will have an associated tun device
created with a name of vnetN, which can also be overridden with the
&lt;target&gt; element. The tun device will be enslaved to the bridge.
The IP range / network configuration is whatever is used on the LAN. This
provides the guest VM full incoming &amp; outgoing net access just like a
physical machine.

<p>
Provides a virtual LAN with NAT to the outside world. The virtual
network has DHCP &amp; DNS services and will give the guest VM addresses
starting from <code>10.0.2.15</code>. The default router will be
<code>10.0.2.2</code> and the DNS server will be <code>10.0.2.3</code>.
This networking is the only option for unprivileged users who need their

<p>
Provides a means for the administrator to execute an arbitrary script
to connect the guest's network to the LAN. The guest will have a tun
device created with a name of vnetN, which can also be overridden with the
&lt;target&gt; element. After creating the tun device a shell script will
be run which is expected to do whatever host network integration is
required. By default this script is called /etc/qemu-ifup but can be

<p>
A multicast group is setup to represent a virtual network. Any VMs
whose network devices are in the same multicast group can talk to each
other even across hosts. This mode is also available to unprivileged
users. There is no default DNS or DHCP support and no outgoing network
access. To provide outgoing network access, one of the VMs should have a
2nd NIC which is connected to one of the first 4 network types and do the
appropriate routing. The multicast protocol is compatible with that used
by user mode linux guests too. The source address used must be from the
multicast address block.

<a name="elementsNICSTCP" id="elementsNICSTCP">TCP tunnel</a>
</h5>
<p>
A TCP client/server architecture provides a virtual network. One VM
provides the server end of the network, all other VMS are configured as
clients. All network traffic is routed between the VMs via the server.
This mode is also available to unprivileged users. There is no default
DNS or DHCP support and no outgoing network access. To provide outgoing

<p>
For hypervisors which support this, you can set the model of
emulated network interface card.
</p>
<p>
The values for <code>type</code> aren't defined specifically by
libvirt, but by what the underlying hypervisor supports (if
any). For QEMU and KVM you can get a list of supported models
with these commands:
</p>
<pre>
qemu -net nic,model=? /dev/null
qemu-kvm -net nic,model=? /dev/null
</pre>

<h4>
<a name="elementsInput" id="elementsInput">Input devices</a>
</h4>
<p>
Input devices allow interaction with the graphical framebuffer in the guest
virtual machine. When enabling the framebuffer, an input device is automatically
provided. It may be possible to add additional devices explicitly, for example,
to provide a graphics tablet for absolute cursor movement.
</p>
<pre>
...
&lt;input type='mouse' bus='usb'/&gt;
...</pre>
<dl><dt><code>input</code></dt><dd>The <code>input</code> element has one mandatory attribute, the <code>type</code>
whose value can be either 'mouse' or 'tablet'. The latter provides absolute
cursor movement, while the former uses relative movement. The optional
<code>bus</code> attribute can be used to refine the exact device type.
It takes values "xen" (paravirtualized), "ps2" and "usb".</dd></dl>
<h4>
<a name="elementsGraphics" id="elementsGraphics">Graphical framebuffers</a>
</h4>
<p>
A graphics device allows for graphical interaction with the
guest OS. A guest will typically have either a framebuffer
or a text console configured to allow interaction with the
admin.
</p>
<pre>
...
&lt;graphics type='vnc' port='5904'/&gt;
...</pre>
<dl><dt><code>graphics</code></dt><dd>The <code>graphics</code> element has a mandatory <code>type</code>
attribute which takes the value "sdl" or "vnc". The former displays
a window on the host desktop, while the latter activates a VNC server.
If the latter is used the <code>port</code> attribute specifies the TCP
port number (with -1 as legacy syntax indicating that it should be
auto-allocated). The <code>autoport</code> attribute is the new
preferred syntax for indicating autoallocation of the TCP port to use.
The <code>listen</code> attribute is an IP address for the server to
listen on. The <code>password</code> attribute provides a VNC password
in clear text.</dd></dl>
<h4>
<a name="elementsConsole" id="elementsConsole">Consoles, serial &amp; parallel devices</a>
</h4>
<p>
A character device provides a way to interact with the virtual machine.
Paravirtualized consoles, serial ports and parallel ports are all
classed as character devices and so represented using the same syntax.
</p>
<pre>
...

vary according to the <code>type</code> attribute on the parent
tag. Allowed variations will be described below</dd><dt><code>target</code></dt><dd>The port number of the character device is specified via the
<code>port</code> attribute, numbered starting from 1. There is
usually only one console device, and 0, 1 or 2 serial devices

&lt;target port='1'&gt;
&lt;/console&gt;
...</pre>
<h5>
<a name="elementsCharFle" id="elementsCharFle">Device logfile</a>

<p>
A file is opened and all data sent to the character
device is written to the file.
</p>
<pre>
...
&lt;serial type="file"&gt;
&lt;source path="/var/log/vm/vm-serial.log"/&gt;
&lt;target port="1"/&gt;

<h5>
<a name="elementsCharVC" id="elementsCharVC">Virtual console</a>
</h5>
<p>
Connects the character device to the graphical framebuffer in
a virtual console. This is typically accessed via a special
hotkey sequence such as "ctrl+alt+3"

&lt;target port="1"/&gt;
&lt;/serial&gt;
...</pre>
<h5>
<a name="elementsCharPTY" id="elementsCharPTY">Pseudo TTY</a>
</h5>
<p>
A Pseudo TTY is allocated using /dev/ptmx. A suitable client
such as 'virsh console' can connect to interact with the
serial port locally.
</p>
<pre>
...
&lt;serial type="pty"&gt;
&lt;source path="/dev/pts/3"/&gt;
&lt;target port="1"/&gt;
&lt;/serial&gt;
...</pre>
<p>
NB special case if &lt;console type='pty'&gt;, then the TTY
path is also duplicated as an attribute tty='/dev/pts/3'
on the top level &lt;console&gt; tag. This provides compat
with existing syntax for &lt;console&gt; tags.
</p>
<h5>
<a name="elementsCharHost" id="elementsCharHost">Host device proxy</a>
</h5>
<p>
The character device is passed through to the underlying
physical character device. The device types must match,
eg the emulated serial port should only be connected to
a host serial port - don't connect a serial port to a parallel
port.
</p>
<pre>

<h1>Domain XML format</h1>
<ul id="toc"></ul>
<p>
This section describes the XML format used to represent domains, there are
variations on the format based on the kind of domains run and the options
used to launch them. For hypervisor specific details consult the
<a href="drivers.html">driver docs</a>
</p>
<h2><a name="elements">Element and attribute overview</a></h2>
<p>
The root element required for all virtual machines is
named <code>domain</code>. It has two attributes, the
<code>type</code> specifies the hypervisor used for running
the domain. The allowed values are driver specific, but
include "xen", "kvm", "qemu", "lxc" and "kqemu". The
second attribute is <code>id</code> which is a unique
integer identifier for the running guest machine. Inactive
machines have no id value.
</p>
<h3><a name="elementsMetadata">General metadata</a></h3>
<pre>
&lt;domain type='xen' id='3'&gt;
&lt;name&gt;fv0&lt;/name&gt;
&lt;uuid&gt;4dea22b31d52d8f32516782e98ab3fa0&lt;/uuid&gt;
...</pre>
<dl>
<dt><code>name</code></dt>
<dd>The content of the <code>name</code> element provides
a short name for the virtual machine. This name should
consist only of alpha-numeric characters and is required
to be unique within the scope of a single host. It is
often used to form the filename for storing the persistent
configuration file. <span class="since">Since 0.0.1</span></dd>
<dt><code>uuid</code></dt>
<dd>The content of the <code>uuid</code> element provides
a globally unique identifier for the virtual machine.
The format must be RFC 4122 compliant, eg <code>3e3fce45-4f53-4fa7-bb32-11f34168b82b</code>.
If omitted when defining/creating a new machine, a random
UUID is generated. <span class="since">Since 0.0.1</span></dd>
</dl>
<h3><a name="elementsOS">Operating system booting</a></h3>
<p>
There are a number of different ways to boot virtual machines
each with their own pros and cons.
</p>
<h4><a name="elementsOSBIOS">BIOS bootloader</a></h4>
<p>
Booting via the BIOS is available for hypervisors supporting
full virtualization. In this case the BIOS has a boot order
priority (floppy, harddisk, cdrom, network) determining where
to obtain/find the boot image.
</p>
<pre>
...
&lt;os&gt;
&lt;type&gt;hvm&lt;/type&gt;
&lt;loader&gt;/usr/lib/xen/boot/hvmloader&lt;/loader&gt;
&lt;boot dev='hd'/&gt;
&lt;/os&gt;
...</pre>
<dl>
<dt><code>type</code></dt>
<dd>The content of the <code>type</code> element specifies the
type of operating system to be booted in the virtual machine.
<code>hvm</code> indicates that the OS is one designed to run
on bare metal, so requires full virtualization. <code>linux</code>
(badly named!) refers to an OS that supports the Xen 3 hypervisor
guest ABI. There are also two optional attributes, <code>arch</code>
specifying the CPU architecture to virtualization, and <code>machine</code>
referring to the machine type. The <a href="formatcaps.html">Capabilities XML</a>
provides details on allowed values for these. <span class="since">Since 0.0.1</span></dd>
<dt><code>loader</code></dt>
<dd>The optional <code>loader</code> tag refers to a firmware blob
used to assist the domain creation process. At this time, it is
only needed by Xen fully virtualized domains. <span class="since">Since 0.1.0</span></dd>
<dt><code>boot</code></dt>
<dd>The <code>dev</code> attribute takes one of the values "fd", "hd",
"cdrom" or "network" and is used to specify the next boot device
to consider. The <code>boot</code> element can be repeated multiple
times to setup a priority list of boot devices to try in turn.
<span class="since">Since 0.1.3</span>
</dd>
</dl>
<h4><a name="elementsOSBootloader">Host bootloader</a></h4>
<p>
Hypervisors employing paravirtualization do not usually emulate
a BIOS, and instead the host is responsible to kicking off the
operating system boot. This may use a pseudo-bootloader in the
host to provide an interface to choose a kernel for the guest.
An example is <code>pygrub</code> with Xen.
</p>
<pre>
...
&lt;bootloader&gt;/usr/bin/pygrub&lt;/bootloader&gt;
&lt;bootloader_args&gt;--append single&lt;/bootloader_args&gt;
...</pre>
<dl>
<dt><code>bootloader</code></dt>
<dd>The content of the <code>bootloader</code> element provides
a fully qualified path to the bootloader executable in the
host OS. This bootloader will be run to choose which kernel
to boot. The required output of the bootloader is dependent
on the hypervisor in use. <span class="since">Since 0.1.0</span></dd>
<dt><code>bootloader_args</code></dt>
<dd>The optional <code>bootloader_args</code> element allows
command line arguments to be passed to the bootloader.
<span class="since">Since 0.2.3</span>
</dd>
</dl>
<h4><a name="elementsOSKernel">Direct kernel boot</a></h4>
<p>
When installing a new guest OS it is often useful to boot directly
from a kernel and initrd stored in the host OS, allowing command
line arguments to be passed directly to the installer. This capability
is usually available for both para and full virtualized guests.
</p>
<pre>
...
&lt;os&gt;
&lt;type&gt;hvm&lt;/type&gt;
&lt;loader&gt;/usr/lib/xen/boot/hvmloader&lt;/loader&gt;
&lt;kernel&gt;/root/f8-i386-vmlinuz&lt;/kernel&gt;
&lt;initrd&gt;/root/f8-i386-initrd&lt;/initrd&gt;
&lt;cmdline&gt;console=ttyS0 ks=http://example.com/f8-i386/os/&lt;/cmdline&gt;
&lt;/os&gt;
...</pre>
<dl>
<dt><code>type</code></dt>
<dd>This element has the same semantics as described earlier in the
<a href="#elementsOSBIOS">BIOS boot section</a></dd>
<dt><code>loader</code></dt>
<dd>This element has the same semantics as described earlier in the
<a href="#elementsOSBIOS">BIOS boot section</a></dd>
<dt><code>kernel</code></dt>
<dd>The contents of this element specify the fully-qualified path
to the kernel image in the host OS.</dd>
<dt><code>initrd</code></dt>
<dd>The contents of this element specify the fully-qualified path
to the (optional) ramdisk image in the host OS.</dd>
<dt><code>cmdline</code></dt>
<dd>The contents of this element specify arguments to be passed to
the kernel (or installer) at boottime. This is often used to
specify an alternate primary console (eg serial port), or the
installation media source / kickstart file</dd>
</dl>
<h3><a name="elementsResources">Basic resources</a></h3>
<pre>
...
&lt;memory&gt;524288&lt;/memory&gt;
&lt;currentMemory&gt;524288&lt;/currentMemory&gt;
&lt;vcpu&gt;1&lt;/vcpu&gt;
...</pre>
<dl>
<dt><code>memory</code></dt>
<dd>The maximum allocation of memory for the guest at boot time.
The units for this value are kilobytes (i.e. blocks of 1024 bytes)</dd>
<dt><code>currentMemory</code></dt>
<dd>The actual allocation of memory for the guest. This value
be less than the maximum allocation, to allow for ballooning
up the guests memory on the fly. If this is omitted, it defaults
to the same value as the <code>memory<code> element</dd>
<dt><code>vcpu</code></dt>
<dd>The content of this element defines the number of virtual
CPUs allocated for the guest OS.</dd>
</dl>
<h3><a name="elementsLifecycle">Lifecycle control</a></h3>
<p>
It is sometimes necessary to override the default actions taken
when a guest OS triggers a lifecycle operation. The following
collections of elements allow the actions to be specified. A
common use case is to force a reboot to be treated as a poweroff
when doing the initial OS installation. This allows the VM to be
re-configured for the first post-install bootup.
</p>
<pre>
...
&lt;on_poweroff&gt;destroy&lt;/on_poweroff&gt;
&lt;on_reboot&gt;restart&lt;/on_reboot&gt;
&lt;on_crash&gt;restart&lt;/on_crash&gt;
...</pre>
<dl>
<dt><code>on_poweroff</code></dt>
<dd>The content of this element specifies the action to take when
the guest requests a poweroff.</dd>
<dt><code>on_reboot</code></dt>
<dd>The content of this element specifies the action to take when
the guest requests a reboot.</dd>
<dt><code>on_crash</code></dt>
<dd>The content of this element specifies the action to take when
the guest crashes.</dd>
</dl>
<p>
Each of these states allow for the same four possible actions.
</p>
<dl>
<dt><code>destroy</code></dt>
<dd>The domain will be terminated completely and all resources
released</dd>
<dt><code>restart</code></dt>
<dd>The domain will be terminated, and then restarted with
the same configuration</dd>
<dt><code>preserve</code></dt>
<dd>The domain will be terminated, and its resource preserved
to allow analysis.</dd>
<dt><code>rename-restart</code></dt>
<dd>The domain will be terminated, and then restarted with
a new name</dd>
</dl>
<h3><a name="elementsFeatures">Hypervisor features</a></h3>
<p>
Hypervisors may allow certain CPU / machine features to be
toggled on/off.
</p>
<pre>
...
&lt;features&gt;
&lt;pae/&gt;
&lt;acpi/&gt;
&lt;apic/&gt;
&lt;/features&gt;
...</pre>
<p>
All features are listed within the <code>features</code>
element, omitting a togglable feature tag turns it off.
The available features can be found by asking
for the <a href="formatcaps.html">capabilities XML</a>,
but a common set for fully virtualized domains are:
</p>
<dl>
<dt><code>pae</code></dt>
<dd>Physical address extension mode allows 32-bit guests
to address more than 4 GB of memory.</dd>
<dt><code>acpi</code></dt>
<dd>ACPI is useful for power management, for example, with
KVM guests it is required for graceful shutdown to work.
</dd>
</dl>
<h3><a name="elementsTime">Time keeping</a></h3>
<p>
The guest clock is typically initialized from the host clock.
Most operating systems expect the hardware clock to be kept
in UTC, and this is the default. Windows, however, expects
it to be in so called 'localtime'.
</p>
<pre>
...
&lt;clock sync="localtime"/&gt;
...</pre>
<dl>
<dt><code>clock</code></dt>
<dd>The <code>sync</code> attribute takes either "utc" or
"localtime" to specify how the guest clock is initialized
in relation to the host OS.
</dd>
</dl>
<h3><a name="elementsDevices">Devices</a></h3>
<p>
The final set of XML elements are all used to describe devices
provided to the guest domain. All devices occur as children
of the main <code>devices</code> element.
<span class="since">Since 0.1.3</span>
</p>
<pre>
...
&lt;devices&gt;
&lt;emulator&gt;/usr/lib/xen/bin/qemu-dm&lt;/emulator&gt;
...</pre>
<dl>
<dt><code>emulator</code></dt>
<dd>
The contents of the <code>emulator</code> element specify
the fully qualified path to the device model emulator binary.
The <a href="formatcaps.html">capabilities XML</a> specifies
the recommended default emulator to use for each particular
domain type / architecture combination.
</dd>
</dl>
<h4><a name="elementsDisks">Hard drives, floppy disks, CDROMs</a></h4>
<p>
Any device that looks like a disk, be it a floppy, harddisk,
cdrom, or paravirtualized driver is specified via the <code>disk</code>
element.
</p>
<pre>
...
&lt;disk type='file'&gt;
&lt;driver name="tap" type="aio"&gt;
&lt;source file='/var/lib/xen/images/fv0'/&gt;
&lt;target dev='hda' bus='ide'/&gt;
&lt;/disk&gt;
...</pre>
<dl>
<dt><code>disk</code></dt>
<dd>The <code>disk</code> element is the main container for describing
disks. The <code>type</code> attribute is either "file" or "block"
and refers to the underlying source for the disk. The optional
<code>device</code> attribute indicates how the disk is to be exposed
to the guest OS. Possible values for this attribute are "floppy", "disk"
and "cdrom", defaulting to "disk".
<span class="since">Since 0.0.3; "device" attribute since 0.1.4</span></dd>
<dt><code>source</code></dt>
<dd>If the disk <code>type</code> is "file", then the <code>file</code> attribute
specifies the fully-qualified path to the file holding the disk. If the disk
<code>type</code> is "block", then the <code>dev</code> attribute specifies
the path to the host device to serve as the disk. <span class="since">Since 0.0.3</span></dd>
<dt><code>target</code></dt>
<dd>The <code>target</code> element controls the bus / device under which the
disk is exposed to the guest OS. The <code>dev</code> attribute indicates
the "logical" device name. The actual device name specified is not guaranteed to map to
the device name in the guest OS. Treat it as a device ordering hint.
The optional <code>bus</code> attribute specifies the type of disk device
to emulate; possible values are driver specific, with typical values being
"ide", "scsi", "virtio", "xen" or "usb". If omitted, the bus type is
inferred from the style of the device name. eg, a device named 'sda'
will typically be exported using a SCSI bus.
<span class="since">Since 0.0.3; <code>bus</code> attribute since 0.4.3;
"usb" attribute value since after 0.4.4</span></dd>
<dt><code>driver</code></dt>
<dd>If the hypervisor supports multiple backend drivers, then the optional
<code>driver</code> element allows them to be selected. The <code>name</code>
attribute is the primary backend driver name, while the optional <code>type</code>
attribute provides the sub-type. <span class="since">Since 0.1.8</span>
</dd>
</dl>
<h4><a name="elementsUSB">USB devices</a></h4>
<p>
USB devices attached to the host can be passed through to the guest using
the <code>hostdev</code> element. <span class="since">since after 0.4.4</span>
</p>
<pre>

&lt;/source&gt;
&lt;/disk&gt;
...</pre>
<dl>
<dt><code>hostdev</code></dt>
<dd>The <code>hostdev</code> element is the main container for describing
host devices. For usb device passthrough <code>mode</code> is always
"subsystem" and <code>type</code> is "usb".
<dt><code>source</code></dt>
<dd>The source element describes the device as seen from the host.
The USB device can either be addressed by vendor / product id using the
<code>vendor</code> and <code>product</code> elements or by the device's
address on the hosts using the <code>address</code> element.</dd>
<dt><code>vendor</code>, <code>product</code></dt>
<dd>The <code>vendor</code> and <code>product</code> elements each have an
<code>id</code> attribute that specifies the USB vendor and product id.
The ids can be given in decimal, hexadecimal (starting with 0x) or
octal (starting with 0) form.</dd>
<dt><code>address</code></dt>
<dd>The <code>address</code> element has a <code>bus</code> and

<p>
<strong><em>
This is the recommended config for general guest connectivity on

</p>
<p>
Provides a virtual network using a bridge device in the host.
Depending on the virtual network configuration, the network may be
totally isolated, NAT'ing to an explicit network device, or NAT'ing to
the default route. DHCP and DNS are provided on the virtual network in
all cases and the IP range can be determined by examining the virtual
network config with '<code>virsh net-dumpxml [networkname]</code>'.
There is one virtual network called 'default' setup out
of the box which does NAT'ing to the default route and has an IP range of
<code>192.168.22.0/255.255.255.0</code>. Each guest will have an
associated tun device created with a name of vnetN, which can also be
overridden with the &lt;target&gt; element.

<p>
Provides a bridge from the VM directly onto the LAN. This assumes
there is a bridge device on the host which has one or more of the hosts
physical NICs enslaved. The guest VM will have an associated tun device
created with a name of vnetN, which can also be overridden with the
&lt;target&gt; element. The tun device will be enslaved to the bridge.
The IP range / network configuration is whatever is used on the LAN. This
provides the guest VM full incoming &amp; outgoing net access just like a
physical machine.
</p>
<pre>
...
&lt;interface type='bridge'&gt;
&lt;source bridge='br0'/&gt;
&lt;/interface&gt;
&lt;interface type='bridge'&gt;
&lt;source bridge='br0'/&gt;
&lt;target dev='vnet7'/&gt;
&lt;mac address="11:22:33:44:55:66"/&gt;
&lt;/interface&gt;
...</pre>
<h5><a name="elementsNICSSlirp">Userspace SLIRP stack</a></h5>
<p>
Provides a virtual LAN with NAT to the outside world. The virtual
network has DHCP &amp; DNS services and will give the guest VM addresses
starting from <code>10.0.2.15</code>. The default router will be
<code>10.0.2.2</code> and the DNS server will be <code>10.0.2.3</code>.
This networking is the only option for unprivileged users who need their
VMs to have outgoing access.
</p>
<pre>
...
&lt;interface type='user'/&gt;
...
&lt;interface type='user'&gt;
&lt;mac address="11:22:33:44:55:66"/&gt;
&lt;/interface&gt;
...</pre>
<h5><a name="elementsNICSEthernet">Generic ethernet connection</a></h5>
<p>
Provides a means for the administrator to execute an arbitrary script
to connect the guest's network to the LAN. The guest will have a tun
device created with a name of vnetN, which can also be overridden with the
&lt;target&gt; element. After creating the tun device a shell script will
be run which is expected to do whatever host network integration is
required. By default this script is called /etc/qemu-ifup but can be
overridden.
</p>
<pre>
...
&lt;interface type='ethernet'/&gt;
...
&lt;interface type='ethernet'&gt;
&lt;target dev='vnet7'/&gt;
&lt;script path='/etc/qemu-ifup-mynet'/&gt;
&lt;/interface&gt;
...</pre>
<h5><a name="elementsNICSMulticast">Multicast tunnel</a></h5>
<p>
A multicast group is setup to represent a virtual network. Any VMs
whose network devices are in the same multicast group can talk to each
other even across hosts. This mode is also available to unprivileged
users. There is no default DNS or DHCP support and no outgoing network
access. To provide outgoing network access, one of the VMs should have a
2nd NIC which is connected to one of the first 4 network types and do the
appropriate routing. The multicast protocol is compatible with that used
by user mode linux guests too. The source address used must be from the
multicast address block.
</p>
<pre>
...
&lt;interface type='mcast'&gt;
&lt;source address='230.0.0.1' port='5558'/&gt;
&lt;/interface&gt;
...</pre>
<h5><a name="elementsNICSTCP">TCP tunnel</a></h5>
<p>
A TCP client/server architecture provides a virtual network. One VM
provides the server end of the network, all other VMS are configured as
clients. All network traffic is routed between the VMs via the server.
This mode is also available to unprivileged users. There is no default
DNS or DHCP support and no outgoing network access. To provide outgoing
network access, one of the VMs should have a 2nd NIC which is connected
to one of the first 4 network types and do the appropriate routing.</p>
<pre>
...
&lt;interface type='server'&gt;
&lt;source address='192.168.0.1' port='5558'/&gt;
&lt;/interface&gt;
...
&lt;interface type='client'&gt;
&lt;source address='192.168.0.1' port='5558'/&gt;
&lt;/interface&gt;
...</pre>
<h5><a name="elementsNICSModel">Setting the NIC model</a></h5>
<pre>
...
&lt;interface type='network'&gt;
&lt;source network='default'/&gt;
&lt;target dev='vnet1'/&gt;
<b>&lt;model type='ne2k_pci'/&gt;</b>
&lt;/interface&gt;
...</pre>
<p>
For hypervisors which support this, you can set the model of
emulated network interface card.
</p>
<p>
The values for <code>type</code> aren't defined specifically by
libvirt, but by what the underlying hypervisor supports (if
any). For QEMU and KVM you can get a list of supported models
with these commands:
</p>
<pre>
qemu -net nic,model=? /dev/null
qemu-kvm -net nic,model=? /dev/null
</pre>
<p>
Typical values for QEMU and KVM include:
ne2k_isa i82551 i82557b i82559er ne2k_pci pcnet rtl8139 e1000 virtio
</p>
<h4><a name="elementsInput">Input devices</a></h4>
<p>
Input devices allow interaction with the graphical framebuffer in the guest
virtual machine. When enabling the framebuffer, an input device is automatically
provided. It may be possible to add additional devices explicitly, for example,
to provide a graphics tablet for absolute cursor movement.
</p>
<pre>
...
&lt;input type='mouse' bus='usb'/&gt;
...</pre>
<dl>
<dt><code>input</code></dt>
<dd>The <code>input</code> element has one mandatory attribute, the <code>type</code>
whose value can be either 'mouse' or 'tablet'. The latter provides absolute
cursor movement, while the former uses relative movement. The optional
<code>bus</code> attribute can be used to refine the exact device type.
It takes values "xen" (paravirtualized), "ps2" and "usb".</dd>
</dl>
<h4><a name="elementsGraphics">Graphical framebuffers</a></h4>
<p>
A graphics device allows for graphical interaction with the
guest OS. A guest will typically have either a framebuffer
or a text console configured to allow interaction with the
admin.
</p>
<pre>
...
&lt;graphics type='vnc' port='5904'/&gt;
...</pre>
<dl>
<dt><code>graphics</code></dt>
<dd>The <code>graphics</code> element has a mandatory <code>type</code>
attribute which takes the value "sdl" or "vnc". The former displays
a window on the host desktop, while the latter activates a VNC server.
If the latter is used the <code>port</code> attribute specifies the TCP
port number (with -1 as legacy syntax indicating that it should be
auto-allocated). The <code>autoport</code> attribute is the new
preferred syntax for indicating autoallocation of the TCP port to use.
The <code>listen</code> attribute is an IP address for the server to
listen on. The <code>password</code> attribute provides a VNC password
in clear text.</dd>
</dl>
<h4><a name="elementsConsole">Consoles, serial &amp; parallel devices</a></h4>
<p>
A character device provides a way to interact with the virtual machine.
Paravirtualized consoles, serial ports and parallel ports are all
classed as character devices and so represented using the same syntax.
</p>
<pre>
...
&lt;parallel type='pty'&gt;
&lt;source path='/dev/pts/2'/&gt;
&lt;target port='0'/&gt;
&lt;/parallel&gt;
&lt;serial type='pty'&gt;
&lt;source path='/dev/pts/3'/&gt;
&lt;target port='0'/&gt;
&lt;/serial&gt;
&lt;console type='pty'&gt;
&lt;source path='/dev/pts/4'/&gt;
&lt;target port='0'/&gt;
&lt;/console&gt;
&lt;/devices&gt;
&lt;/domain&gt;</pre>
<dl>
<dt><code>parallel</code></dt>
<dd>Represents a parallel port</dd>
<dt><code>serial</code></dt>
<dd>Represents a serial port</dd>
<dt><code>console</code></dt>
<dd>Represents the primary console. This can be the paravirtualized
console with Xen guests, or duplicates the primary serial port
for fully virtualized guests without a paravirtualized console.</dd>
<dt><code>source</code></dt>
<dd>The attributes available for the <code>source</code> element
vary according to the <code>type</code> attribute on the parent
tag. Allowed variations will be described below</dd>
<dt><code>target</code></dt>
<dd>The port number of the character device is specified via the
<code>port</code> attribute, numbered starting from 1. There is
usually only one console device, and 0, 1 or 2 serial devices
or parallel devices.
</dl>
<h5><a name="elementsCharSTDIO">Domain logfile</a></h5>
<p>
This disables all input on the character device, and sends output
into the virtual machine's logfile
</p>
<pre>
...
&lt;console type='stdio'&gt;
&lt;target port='1'&gt;
&lt;/console&gt;
...</pre>
<h5><a name="elementsCharFle">Device logfile</a></h5>
<p>
A file is opened and all data sent to the character
device is written to the file.
</p>
<pre>
...
&lt;serial type="file"&gt;
&lt;source path="/var/log/vm/vm-serial.log"/&gt;
&lt;target port="1"/&gt;
&lt;/serial&gt;
...</pre>
<h5><a name="elementsCharVC">Virtual console</a></h5>
<p>
Connects the character device to the graphical framebuffer in
a virtual console. This is typically accessed via a special
hotkey sequence such as "ctrl+alt+3"
</p>
<pre>
...
&lt;serial type='vc'&gt;
&lt;target port="1"/&gt;
&lt;/serial&gt;
...</pre>
<h5><a name="elementsCharNull">Null device</a></h5>
<p>
Connects the character device to the void. No data is ever
provided to the input. All data written is discarded.
</p>
<pre>
...
&lt;serial type='null'&gt;
&lt;target port="1"/&gt;
&lt;/serial&gt;
...</pre>
<h5><a name="elementsCharPTY">Pseudo TTY</a></h5>
<p>
A Pseudo TTY is allocated using /dev/ptmx. A suitable client
such as 'virsh console' can connect to interact with the
serial port locally.
</p>
<pre>
...
&lt;serial type="pty"&gt;
&lt;source path="/dev/pts/3"/&gt;
&lt;target port="1"/&gt;
&lt;/serial&gt;
...</pre>
<p>
NB special case if &lt;console type='pty'&gt;, then the TTY
path is also duplicated as an attribute tty='/dev/pts/3'
on the top level &lt;console&gt; tag. This provides compat
with existing syntax for &lt;console&gt; tags.
</p>
<h5><a name="elementsCharHost">Host device proxy</a></h5>
<p>
The character device is passed through to the underlying
physical character device. The device types must match,
eg the emulated serial port should only be connected to
a host serial port - don't connect a serial port to a parallel
port.
</p>
<pre>
...
&lt;serial type="dev"&gt;
&lt;source path="/dev/ttyS0"/&gt;
&lt;target port="1"/&gt;
&lt;/serial&gt;
...</pre>
<h5><a name="elementsCharTCP">TCP client/server</a></h5>
<p>
The character device acts as a TCP client connecting to a
remote server, or as a server waiting for a client connection.
</p>
<pre>
...
&lt;serial type="tcp"&gt;
&lt;source mode="connect" host="0.0.0.0" service="2445"/&gt;
&lt;wiremode type="telnet"/&gt;
&lt;target port="1"/&gt;
&lt;/serial&gt;
...</pre>
<h5><a name="elementsCharUDP">UDP network console</a></h5>
<p>
The character device acts as a UDP netconsole service,
sending and receiving packets. This is a lossy service.
</p>
<pre>
...
&lt;serial type="udp"&gt;
&lt;source mode="bind" host="0.0.0.0" service="2445"/&gt;
&lt;source mode="connect" host="0.0.0.0" service="2445"/&gt;
&lt;target port="1"/&gt;
&lt;/serial&gt;
...</pre>
<h5><a name="elementsCharUNIX">UNIX domain socket client/server</a></h5>
<p>
The character device acts as a UNIX domain socket server,
accepting connections from local clients.
</p>
<pre>
...
&lt;serial type="unix"&gt;
&lt;source mode="bind" path="/tmp/foo"/&gt;
&lt;target port="1"/&gt;
&lt;/serial&gt;
...</pre>

This page provides an introduction to the network XML format. For background
information on the concepts referred to here, consult the <a href="archnetwork.html">network driver architecture</a>
page.
</p>
<h2>
<a name="elements" id="elements">Element and attribute overview</a>
</h2>
<p>
The root element required for all virtual networks is
named <code>network</code> and has no attributes.
The network XML format is available <span class="since">since 0.3.0</span>
</p>
<h3>
<a name="elementsMetadata" id="elementsMetadata">General metadata</a>
</h3>
<p>
The first elements provide basic metadata about the virtual
network.
</p>
<pre>
&lt;network&gt;
&lt;name&gt;default&lt;/name&gt;
&lt;uuid&gt;3e3fce45-4f53-4fa7-bb32-11f34168b82b&lt;/uuid&gt;
...</pre>
<dl><dt><code>name</code></dt><dd>The content of the <code>name</code> element provides
a short name for the virtual network. This name should
consist only of alpha-numeric characters and is required
to be unique within the scope of a single host. It is
used to form the filename for storing the persistent
configuration file. <span class="since">Since 0.3.0</span></dd><dt><code>uuid</code></dt><dd>The content of the <code>uuid</code> element provides
a globally unique identifier for the virtual network.
The format must be RFC 4122 compliant, eg <code>3e3fce45-4f53-4fa7-bb32-11f34168b82b</code>.
If omitted when defining/creating a new network, a random
UUID is generated. <span class="since">Since 0.3.0</span></dd></dl>
<h3>
<a name="elementsConnect" id="elementsConnect">Connectivity</a>
</h3>
<p>
The next set of elements control how a virtual network is
provided connectivity to the physical LAN (if at all).
</p>
<pre>
...
&lt;bridge name="virbr0" /&gt;
&lt;forward mode="nat" dev="eth0"/&gt;
...</pre>
<dl><dt><code>bridge</code></dt><dd>The <code>name</code> attribute on the <code>bridge</code> element
defines the name of a bridge device which will be used to construct
the virtual network. The virtual machines will be connected to this
bridge device allowing them to talk to each other. The bridge device
may also be connected to the LAN. It is recommended that bridge
device names started with the prefix <code>vir</code>, but the name
<code>virbr0</code> is reserved for the "default" virtual network.
This element should always be provided when defining a new network.
<span class="since">Since 0.3.0</span>
</dd><dt><code>forward</code></dt><dd>Inclusion of the <code>forward</code> element indicates that
the virtual network is to be connected to the physical LAN. If
no attributes are set, NAT forwarding will be used for connectivity.
Firewall rules will allow forwarding to any other network device whether
ethernet, wireless, dialup, or VPN. If the <code>dev</code> attribute
is set, the firewall rules will restrict forwarding to the named
device only. If the <code>mode</code> attribute is set to <code>route</code>
then the traffic will not have NAT applied. This presumes that the
local LAN router has suitable routing table entries to return traffic
to this host. <span class="since">Since 0.3.0; 'mode' attribute since
0.4.2</span></dd></dl>
<h3>
<a name="elementsAddress" id="elementsAddress">Addressing</a>
</h3>
<p>
The final set of elements define the IPv4 address range available,
and optionally enable DHCP sevices.
</p>
<pre>
...
&lt;ip address="192.168.122.1" netmask="255.255.255.0"&gt;
&lt;dhcp&gt;
&lt;range start="192.168.122.2" end="192.168.122.254" /&gt;
&lt;/dhcp&gt;
&lt;/ip&gt;
&lt;/network&gt;</pre>
<dl><dt><code>ip</code></dt><dd>The <code>address</code> attribute defines an IPv4 address in
dotted-decimal format, that will be configured on the bridge
device associated with the virtual network. To the guests this
address will be their default route. The <code>netmask</code>
attribute defines the significant bits of the network address,
again specified in dotted-decimal format. <span class="since">Since 0.3.0</span>
</dd><dt><code>dhcp</code></dt><dd>Immediately within the <code>ip</code> element there is an
optional <code>dhcp</code> element. The presence of this element
enables DHCP services on the virtual network. It will further
contain one or more <code>range</code> elements.
<span class="since">Since 0.3.0</span>
</dd><dt><code>range</code></dt><dd>The <code>start</code> and <code>end</code> attributes on the
<code>range</code> element specify the boundaries of a pool of
IPv4 addresses to be provided to DHCP clients. These two addresses
must lie within the scope of the network defined on the parent
<code>ip</code> element. <span class="since">Since 0.3.0</span>
</dd></dl>
<h2>
<a name="examples" id="examples">Example configuration</a>
</h2>
<h3>
<a name="examplesNAT" id="examplesNAT">NAT based network</a>
</h3>
<p>
This example is the so called "default" virtual network. It is
provided and enabled out-of-the-box for all libvirt installations.
This is a configuration that allows guest OS to get outbound
connectivity regardless of whether the host uses ethernet, wireless,
dialup, or VPN networking without requiring any specific admin
configuration. In the absence of host networking, it at least allows
guests to talk directly to each other.
</p>
<pre>
&lt;network&gt;
&lt;name&gt;default&lt;/name&gt;
&lt;bridge name="virbr0" /&gt;
&lt;forward mode="nat"/&gt;
&lt;ip address="192.168.122.1" netmask="255.255.255.0"&gt;
&lt;dhcp&gt;
&lt;range start="192.168.122.2" end="192.168.122.254" /&gt;
&lt;/dhcp&gt;
&lt;/ip&gt;
&lt;/network&gt;</pre>
<h3>
<a name="examplesRoute" id="examplesRoute">Routed network config</a>
</h3>
<p>
This is a variant on the default network which routes traffic
from the virtual network to the LAN without applying any NAT.
It requires that the IP address range be pre-configured in the
routing tables of the router on the host network. This example
further specifies that guest traffic may only go out via the
<code>eth1</code> host network device.
</p>
<pre>
&lt;network&gt;
&lt;name&gt;local&lt;/name&gt;
&lt;bridge name="virbr1" /&gt;
&lt;forward mode="route" dev="eth1"/&gt;
&lt;ip address="192.168.122.1" netmask="255.255.255.0"&gt;
&lt;dhcp&gt;
&lt;range start="192.168.122.2" end="192.168.122.254" /&gt;
&lt;/dhcp&gt;
&lt;/ip&gt;
&lt;/network&gt;</pre>
<h3>
<a name="examplesPrivate" id="examplesPrivate">Isolated network config</a>
</h3>
<p>
This variant provides a completely isolated private network
for guests. The guests can talk to each other, and the host
OS, but cannot reach any other machines on the LAN, due to
the omission of the <code>forward</code> element in the XML
description.
</p>
<pre>
&lt;network&gt;
&lt;name&gt;private&lt;/name&gt;
&lt;bridge name="virbr2" /&gt;
&lt;ip address="192.168.152.1" netmask="255.255.255.0"&gt;
&lt;dhcp&gt;
&lt;range start="192.168.152.2" end="192.168.152.254" /&gt;
&lt;/dhcp&gt;
&lt;/ip&gt;

&lt;uuid&gt;3e3fce45-4f53-4fa7-bb32-11f34168b82b&lt;/uuid&gt;
...</pre>
<dl>
<dt><code>name</code></dt>
<dd>The content of the <code>name</code> element provides
a short name for the virtual network. This name should
consist only of alpha-numeric characters and is required
to be unique within the scope of a single host. It is
used to form the filename for storing the persistent
configuration file. <span class="since">Since 0.3.0</span></dd>
<dt><code>uuid</code></dt>
<dd>The content of the <code>uuid</code> element provides
a globally unique identifier for the virtual network.
The format must be RFC 4122 compliant, eg <code>3e3fce45-4f53-4fa7-bb32-11f34168b82b</code>.
If omitted when defining/creating a new network, a random
UUID is generated. <span class="since">Since 0.3.0</span></dd>
</dl>
<h3><a name="elementsConnect">Connectivity</a></h3>
<p>
The next set of elements control how a virtual network is
provided connectivity to the physical LAN (if at all).
</p>
<pre>
...
&lt;bridge name="virbr0" /&gt;
&lt;forward mode="nat" dev="eth0"/&gt;
...</pre>
<dl>
<dt><code>bridge</code></dt>
<dd>The <code>name</code> attribute on the <code>bridge</code> element
defines the name of a bridge device which will be used to construct
the virtual network. The virtual machines will be connected to this
bridge device allowing them to talk to each other. The bridge device
may also be connected to the LAN. It is recommended that bridge
device names started with the prefix <code>vir</code>, but the name
<code>virbr0</code> is reserved for the "default" virtual network.
This element should always be provided when defining a new network.
<span class="since">Since 0.3.0</span>
</dd>
<dt><code>forward</code></dt>
<dd>Inclusion of the <code>forward</code> element indicates that
the virtual network is to be connected to the physical LAN. If
no attributes are set, NAT forwarding will be used for connectivity.
Firewall rules will allow forwarding to any other network device whether
ethernet, wireless, dialup, or VPN. If the <code>dev</code> attribute
is set, the firewall rules will restrict forwarding to the named
device only. If the <code>mode</code> attribute is set to <code>route</code>
then the traffic will not have NAT applied. This presumes that the
local LAN router has suitable routing table entries to return traffic
to this host. <span class="since">Since 0.3.0; 'mode' attribute since
0.4.2</span></dd>
</dl>
<h3><a name="elementsAddress">Addressing</a></h3>
<p>
The final set of elements define the IPv4 address range available,
and optionally enable DHCP sevices.
</p>
<pre>
...
&lt;ip address="192.168.122.1" netmask="255.255.255.0"&gt;
&lt;dhcp&gt;
&lt;range start="192.168.122.2" end="192.168.122.254" /&gt;
&lt;/dhcp&gt;
&lt;/ip&gt;
&lt;/network&gt;</pre>
<dl>
<dt><code>ip</code></dt>
<dd>The <code>address</code> attribute defines an IPv4 address in
dotted-decimal format, that will be configured on the bridge
device associated with the virtual network. To the guests this
address will be their default route. The <code>netmask</code>
attribute defines the significant bits of the network address,
again specified in dotted-decimal format. <span class="since">Since 0.3.0</span>
</dd>
<dt><code>dhcp</code></dt>
<dd>Immediately within the <code>ip</code> element there is an
optional <code>dhcp</code> element. The presence of this element
enables DHCP services on the virtual network. It will further
contain one or more <code>range</code> elements.
<span class="since">Since 0.3.0</span>
</dd>
<dt><code>range</code></dt>
<dd>The <code>start</code> and <code>end</code> attributes on the
<code>range</code> element specify the boundaries of a pool of
IPv4 addresses to be provided to DHCP clients. These two addresses
must lie within the scope of the network defined on the parent
<code>ip</code> element. <span class="since">Since 0.3.0</span>
</dd>
</dl>
<h2><a name="examples">Example configuration</a></h2>
<h3><a name="examplesNAT">NAT based network</a></h3>
<p>
This example is the so called "default" virtual network. It is
provided and enabled out-of-the-box for all libvirt installations.
This is a configuration that allows guest OS to get outbound
connectivity regardless of whether the host uses ethernet, wireless,
dialup, or VPN networking without requiring any specific admin
configuration. In the absence of host networking, it at least allows
guests to talk directly to each other.
</p>
<pre>
&lt;network&gt;
&lt;name&gt;default&lt;/name&gt;
&lt;bridge name="virbr0" /&gt;
&lt;forward mode="nat"/&gt;
&lt;ip address="192.168.122.1" netmask="255.255.255.0"&gt;
&lt;dhcp&gt;
&lt;range start="192.168.122.2" end="192.168.122.254" /&gt;
&lt;/dhcp&gt;
&lt;/ip&gt;
&lt;/network&gt;</pre>
<h3><a name="examplesRoute">Routed network config</a></h3>
<p>
This is a variant on the default network which routes traffic
from the virtual network to the LAN without applying any NAT.
It requires that the IP address range be pre-configured in the
routing tables of the router on the host network. This example
further specifies that guest traffic may only go out via the
<code>eth1</code> host network device.
</p>
<pre>
&lt;network&gt;
&lt;name&gt;local&lt;/name&gt;
&lt;bridge name="virbr1" /&gt;
&lt;forward mode="route" dev="eth1"/&gt;
&lt;ip address="192.168.122.1" netmask="255.255.255.0"&gt;
&lt;dhcp&gt;
&lt;range start="192.168.122.2" end="192.168.122.254" /&gt;
&lt;/dhcp&gt;
&lt;/ip&gt;
&lt;/network&gt;</pre>
<h3><a name="examplesPrivate">Isolated network config</a></h3>
<p>
This variant provides a completely isolated private network
for guests. The guests can talk to each other, and the host
OS, but cannot reach any other machines on the LAN, due to
the omission of the <code>forward</code> element in the XML
description.
</p>
<pre>
&lt;network&gt;
&lt;name&gt;private&lt;/name&gt;
&lt;bridge name="virbr2" /&gt;
&lt;ip address="192.168.152.1" netmask="255.255.255.0"&gt;
&lt;dhcp&gt;
&lt;range start="192.168.152.2" end="192.168.152.254" /&gt;
&lt;/dhcp&gt;
&lt;/ip&gt;
&lt;/network&gt;</pre>

<h2>
<a name="StoragePool" id="StoragePool">Storage pool XML</a>

<p>
Although all storage pool backends share the same public APIs and
XML format, they have varying levels of capabilities. Some may
allow creation of volumes, others may only allow use of pre-existing
volumes. Some may have constraints on volume size, or placement.
</p>
<p>
The is the top level tag for a storage pool document is 'pool'. It has
a single attribute <code>type</code>, which is one of <code>dir</code>,
<code>fs</code>,<code>netfs</code>,<code>disk</code>,<code>iscsi</code>,
<code>logical</code>. This corresponds to the storage backend drivers
listed further along in this document.
The storage pool XML format is available <span class="since">since 0.4.1</span>

<h3>
<a name="StoragePoolSource" id="StoragePoolSource">Source elements</a>
</h3>
<p>
A single <code>source</code> element is contained within the top level
<code>pool</code> element. This tag is used to describe the source of
the storage pool. It can contain the following child elements:
</p>
<pre>
...
&lt;source&gt;
&lt;host name="iscsi.example.com"/&gt;
&lt;device path="demo-target"/&gt;
&lt;/source&gt;
...</pre>
<dl><dt><code>device</code></dt><dd>Provides the source for pools backed by physical devices.

a single attribute <code>path</code> which is the fully qualified
path to the block device node. <span class="since">Since 0.4.1</span></dd><dt><code>directory</code></dt><dd>Provides the source for pools backed by directories. May
only occur once. Contains a single attribute <code>path</code>
which is the fully qualified path to the block device node.
<span class="since">Since 0.4.1</span></dd><dt><code>host</code></dt><dd>Provides the source for pools backed by storage from a
remote server. Will be used in combination with a <code>directory</code>
or <code>device</code> element. Contains an attribute <code>name</code>
which is the hostname or IP address of the server. May optionally
contain a <code>port</code> attribute for the protocol specific
port number. <span class="since">Since 0.4.1</span></dd><dt><code>name</code></dt><dd>Provides the source for pools backed by storage from a
named element (e.g., a logical volume group name).
remote server. Contains a string identifier.
<span class="since">Since 0.4.5</span></dd><dt><code>format</code></dt><dd>Provides information about the format of the pool. This
contains a single attribute <code>type</code> whose value is
backend specific. This is typically used to indicate filesystem
type, or network filesystem type, or partition table type, or
LVM metadata type. All drivers are required to have a default
value for this, so it is optional. <span class="since">Since 0.4.1</span></dd></dl>
<h3>
<a name="StoragePoolTarget" id="StoragePoolTarget">Target elements</a>
</h3>
<p>
A single <code>target</code> element is contained within the top level
<code>pool</code> element. This tag is used to describe the mapping of
the storage pool into the host filesystem. It can contain the following
child elements:
</p>
<pre>
...
&lt;target&gt;
&lt;path&gt;/dev/disk/by-path&lt;/path&gt;
&lt;permissions&gt;
&lt;owner&gt;0744&lt;/owner&gt;
&lt;group&gt;0744&lt;/group&gt;
&lt;mode&gt;0744&lt;/mode&gt;
&lt;label&gt;virt_image_t&lt;/label&gt;
&lt;/permissions&gt;
&lt;/target&gt;
&lt;/pool&gt;</pre>
<dl><dt><code>path</code></dt><dd>Provides the location at which the pool will be mapped into
the local filesystem namespace. For a filesystem/directory based
pool it will be the name of the directory in which volumes will
be created. For device based pools it will be the name of the directory in which
devices nodes exist. For the latter <code>/dev/</code> may seem
like the logical choice, however, devices nodes there are not
guaranteed stable across reboots, since they are allocated on
demand. It is preferable to use a stable location such as one
of the <code>/dev/disk/by-{path,id,uuid,label</code> locations.
<span class="since">Since 0.4.1</span>
</dd><dt><code>permissions</code></dt><dd>Provides information about the default permissions to use
when creating volumes. This is currently only useful for directory
or filesystem based pools, where the volumes allocated are simple
files. For pools where the volumes are device nodes, the hotplug
scripts determine permissions. It contains 4 child elements. The
<code>mode</code> element contains the octal permission set. The
<code>owner</code> element contains the numeric user ID. The <code>group</code>
element contains the numeric group ID. The <code>label</code> element
contains the MAC (eg SELinux) label string.
<span class="since">Since 0.4.1</span>
</dd></dl>
<h3>
<a name="StoragePoolExtents" id="StoragePoolExtents">Device extents</a>
</h3>
<p>
If a storage pool exposes information about its underlying
placement / allocation scheme, the <code>device</code> element
within the <code>source</code> element may contain information
about its available extents. Some pools have a constraint that
a volume must be allocated entirely within a single constraint
(eg disk partition pools). Thus the extent information allows an
application to determine the maximum possible size for a new
volume
</p>
<p>
For storage pools supporting extent information, within each
<code>device</code> element there will be zero or more <code>freeExtent</code>
elements. Each of these elements contains two attributes, <code>start</code>
and <code>end</code> which provide the boundaries of the extent on the
device, measured in bytes. <span class="since">Since 0.4.1</span>
</p>
<h2>
<a name="StorageVol" id="StorageVol">Storage volume XML</a>
</h2>
<p>
A storage volume will be either a file or a device node.
The storage volume XML format is available <span class="since">since 0.4.1</span>
</p>
<h3>

&lt;capacity unit="T"&gt;1&lt;/capacity&gt;
...</pre>
<dl><dt><code>name</code></dt><dd>Providing a name for the volume which is unique to the pool.
This is mandatory when defining a volume. <span class="since">Since 0.4.1</span></dd><dt><code>key</code></dt><dd>Providing an identifier for the volume which is globally unique.
This is optional when defining a volume, a key will be generated if
omitted. <span class="since">Since 0.4.1</span></dd><dt><code>allocation</code></dt><dd>Providing the total storage allocation for the volume. This
may be smaller than the logical capacity if the volume is sparsely
allocated. It may also be larger than the logical capacity if the
volume has substantial metadata overhead. This value is in bytes.
If omitted when creating a volume, the volume will be fully
allocated at time of creation. If set to a value smaller than the
capacity, the pool has the <strong>option</strong> of deciding
to sparsely allocate a volume. It does not have to honour requests
for sparse allocation though. <span class="since">Since 0.4.1</span></dd><dt><code>capacity</code></dt><dd>Providing the logical capacity for the volume. This value is
in bytes. This is compulsory when creating a volume.

<h1>Storage pool and volume XML format</h1>
<ul id="toc"></ul>
<h2><a name="StoragePool">Storage pool XML</a></h2>
<p>
Although all storage pool backends share the same public APIs and
XML format, they have varying levels of capabilities. Some may
allow creation of volumes, others may only allow use of pre-existing
volumes. Some may have constraints on volume size, or placement.
</p>
<p>
The is the top level tag for a storage pool document is 'pool'. It has
a single attribute <code>type</code>, which is one of <code>dir</code>,
<code>fs</code>,<code>netfs</code>,<code>disk</code>,<code>iscsi</code>,
<code>logical</code>. This corresponds to the storage backend drivers
listed further along in this document.
The storage pool XML format is available <span class="since">since 0.4.1</span>
</p>
<h3><a name="StoragePoolFirst">General metadata</a></h3>
<pre>
&lt;pool type="iscsi"&gt;
&lt;name&gt;virtimages&lt;/name&gt;
&lt;uuid&gt;3e3fce45-4f53-4fa7-bb32-11f34168b82b&lt;/uuid&gt;
&lt;allocation&gt;10000000&lt;/allocation&gt;
&lt;capacity&gt;50000000&lt;/capacity&gt;
&lt;available&gt;40000000&lt;/available&gt;
...</pre>
<dl>
<dt><code>name</code></dt>
<dd>Providing a name for the pool which is unique to the host.
This is mandatory when defining a pool. <span class="since">Since 0.4.1</span></dd>
<dt><code>uuid</code></dt>
<dd>Providing an identifier for the pool which is globally unique.
This is optional when defining a pool, a UUID will be generated if
omitted. <span class="since">Since 0.4.1</span></dd>
<dt><code>allocation</code></dt>
<dd>Providing the total storage allocation for the pool. This may
be larger than the sum of the allocation of all volumes due to
metadata overhead. This value is in bytes. This is not applicable
when creating a pool. <span class="since">Since 0.4.1</span></dd>
<dt><code>capacity</code></dt>
<dd>Providing the total storage capacity for the pool. Due to
underlying device constraints it may not be possible to use the
full capacity for storage volumes. This value is in bytes. This
is not applicable when creating a pool. <span class="since">Since 0.4.1</span></dd>
<dt><code>available</code></dt>
<dd>Providing the free space available for allocating new volumes
in the pool. Due to underlying device constraints it may not be
possible to allocate the entire free space to a single volume.
This value is in bytes. This is not applicable when creating a
pool. <span class="since">Since 0.4.1</span></dd>
</dl>
<h3><a name="StoragePoolSource">Source elements</a></h3>
<p>
A single <code>source</code> element is contained within the top level
<code>pool</code> element. This tag is used to describe the source of
the storage pool. It can contain the following child elements:
</p>
<pre>
...
&lt;source&gt;
&lt;host name="iscsi.example.com"/&gt;
&lt;device path="demo-target"/&gt;
&lt;/source&gt;
...</pre>
<dl>
<dt><code>device</code></dt>
<dd>Provides the source for pools backed by physical devices.
May be repeated multiple times depending on backend driver. Contains
a single attribute <code>path</code> which is the fully qualified
path to the block device node. <span class="since">Since 0.4.1</span></dd>
<dt><code>directory</code></dt>
<dd>Provides the source for pools backed by directories. May
only occur once. Contains a single attribute <code>path</code>
which is the fully qualified path to the block device node.
<span class="since">Since 0.4.1</span></dd>
<dt><code>host</code></dt>
<dd>Provides the source for pools backed by storage from a
remote server. Will be used in combination with a <code>directory</code>
or <code>device</code> element. Contains an attribute <code>name</code>
which is the hostname or IP address of the server. May optionally
contain a <code>port</code> attribute for the protocol specific
port number. <span class="since">Since 0.4.1</span></dd>
<dt><code>name</code></dt>
<dd>Provides the source for pools backed by storage from a
named element (e.g., a logical volume group name).
remote server. Contains a string identifier.
<span class="since">Since 0.4.5</span></dd>
<dt><code>format</code></dt>
<dd>Provides information about the format of the pool. This
contains a single attribute <code>type</code> whose value is
backend specific. This is typically used to indicate filesystem
type, or network filesystem type, or partition table type, or
LVM metadata type. All drivers are required to have a default
value for this, so it is optional. <span class="since">Since 0.4.1</span></dd>
</dl>
<h3><a name="StoragePoolTarget">Target elements</a></h3>
<p>
A single <code>target</code> element is contained within the top level
<code>pool</code> element. This tag is used to describe the mapping of
the storage pool into the host filesystem. It can contain the following
child elements:
</p>
<pre>
...
&lt;target&gt;
&lt;path&gt;/dev/disk/by-path&lt;/path&gt;
&lt;permissions&gt;
&lt;owner&gt;0744&lt;/owner&gt;
&lt;group&gt;0744&lt;/group&gt;
&lt;mode&gt;0744&lt;/mode&gt;
&lt;label&gt;virt_image_t&lt;/label&gt;
&lt;/permissions&gt;
&lt;/target&gt;
&lt;/pool&gt;</pre>
<dl>
<dt><code>path</code></dt>
<dd>Provides the location at which the pool will be mapped into
the local filesystem namespace. For a filesystem/directory based
pool it will be the name of the directory in which volumes will
be created. For device based pools it will be the name of the directory in which
devices nodes exist. For the latter <code>/dev/</code> may seem
like the logical choice, however, devices nodes there are not
guaranteed stable across reboots, since they are allocated on
demand. It is preferable to use a stable location such as one
of the <code>/dev/disk/by-{path,id,uuid,label</code> locations.
<span class="since">Since 0.4.1</span>
</dd>
<dt><code>permissions</code></dt>
<dd>Provides information about the default permissions to use
when creating volumes. This is currently only useful for directory
or filesystem based pools, where the volumes allocated are simple
files. For pools where the volumes are device nodes, the hotplug
scripts determine permissions. It contains 4 child elements. The
<code>mode</code> element contains the octal permission set. The
<code>owner</code> element contains the numeric user ID. The <code>group</code>
element contains the numeric group ID. The <code>label</code> element
contains the MAC (eg SELinux) label string.
<span class="since">Since 0.4.1</span>
</dd>
</dl>
<h3><a name="StoragePoolExtents">Device extents</a></h3>
<p>
If a storage pool exposes information about its underlying
placement / allocation scheme, the <code>device</code> element
within the <code>source</code> element may contain information
about its available extents. Some pools have a constraint that
a volume must be allocated entirely within a single constraint
(eg disk partition pools). Thus the extent information allows an
application to determine the maximum possible size for a new
volume
</p>
<p>
For storage pools supporting extent information, within each
<code>device</code> element there will be zero or more <code>freeExtent</code>
elements. Each of these elements contains two attributes, <code>start</code>
and <code>end</code> which provide the boundaries of the extent on the
device, measured in bytes. <span class="since">Since 0.4.1</span>
</p>
<h2><a name="StorageVol">Storage volume XML</a></h2>
<p>
A storage volume will be either a file or a device node.
The storage volume XML format is available <span class="since">since 0.4.1</span>
</p>
<h3><a name="StorageVolFirst">General metadata</a></h3>
<pre>
&lt;volume type="file"&gt;
&lt;name&gt;sparse.img&lt;/name&gt;
&lt;key&gt;/var/lib/xen/images/sparse.img&lt;/key&gt;
&lt;allocation&gt;0&lt;/allocation&gt;
&lt;capacity unit="T"&gt;1&lt;/capacity&gt;
...</pre>
<dl>
<dt><code>name</code></dt>
<dd>Providing a name for the volume which is unique to the pool.
This is mandatory when defining a volume. <span class="since">Since 0.4.1</span></dd>
<dt><code>key</code></dt>
<dd>Providing an identifier for the volume which is globally unique.
This is optional when defining a volume, a key will be generated if
omitted. <span class="since">Since 0.4.1</span></dd>
<dt><code>allocation</code></dt>
<dd>Providing the total storage allocation for the volume. This
may be smaller than the logical capacity if the volume is sparsely
allocated. It may also be larger than the logical capacity if the
volume has substantial metadata overhead. This value is in bytes.
If omitted when creating a volume, the volume will be fully
allocated at time of creation. If set to a value smaller than the
capacity, the pool has the <strong>option</strong> of deciding
to sparsely allocate a volume. It does not have to honour requests
for sparse allocation though. <span class="since">Since 0.4.1</span></dd>
<dt><code>capacity</code></dt>
<dd>Providing the logical capacity for the volume. This value is
in bytes. This is compulsory when creating a volume.
<span class="since">Since 0.4.1</span></dd>
<dt><code>source</code></dt>
<dd>Provides information about the underlying storage allocation
of the volume. This may not be available for some pool types.
<span class="since">Since 0.4.1</span></dd>
<dt><code>target</code></dt>
<dd>Provides information about the representation of the volume
on the local host. <span class="since">Since 0.4.1</span></dd>

<span class="since">Since 0.4.1</span></dd>
<dt><code>format</code></dt>
<dd>Provides information about the pool specific volume format.
