b5a34d96ff rpc: Fix crash on error paths of message dispatching
This patch resolves CVE-2013-0170:
https://bugzilla.redhat.com/show_bug.cgi?id=893450

When reading and dispatching of a message failed the message was freed
but wasn't removed from the message queue.

After that when the connection was about to be closed the pointer for
the message was still present in the queue and it was passed to
virNetMessageFree which tried to call the callback function from an
uninitialized pointer.

This patch removes the message from the queue before it's freed.

bebe5122b9 qemu: Clear async job when p2p migration fails early
When p2p migration fails early because qemuMigrationIsAllowed or
qemuMigrationIsSafe say migration should be cancelled, we fail to clear
the migration-out async job. As a result of that, further APIs called
for the same domain may fail with Timed out during operation: cannot
acquire state change lock.

96d4cd58f5 security: Fix libvirtd crash possibility
Fix for CVE-2012-4423.

When generating RPC protocol messages, it's strictly needed to have a
continuous line of numbers or RPC messages. However in case anyone
tries backporting some functionality and will skip a number, there is
a possibility to make the daemon segfault with newer virsh (version of
the library, rpc call, etc.) even unintentionally.

The problem is that the skipped numbers will get func filled with
NULLs, but there is no check whether these are set before the daemon
tries to run them. This patch very simply enhances one check and fixes
that.

6cde2d3965 build: drop check for ANSI compiler
Using automake.git (will become 1.12 someday), I got this error:

configure.ac:90: error: automatic de-ANSI-fication support has been removed

In short, pre-C89 compilers are no longer a viable portability
target.  Besides, our code base already requires C99, so worrying
about pre-C89 seems pointless.

06e1daac70 test: fix segfault in networkxml2argvtest
This bug resolves https://bugzilla.redhat.com/show_bug.cgi?id=810100

rpm builds for i686 were failing with a segfault in
networkxml2argvtest. Running under valgrind showed that a region of
memory was being referenced after it had been freed (as the result of
realloc - see the valgrind report in the BZ).

The problem (in replaceTokens() - added in commit 22ec60, meaning this
bug was in 0.9.10 and 0.9.11) was that the pointers token_start and
token_end were being computed based on the value of *buf, then *buf
was being realloc'ed (potentially moving it), then token_start and
token_end were used without recomputing them to account for movement
of *buf.

The solution is to change the code so that token_start and token_end
are offsets into *buf rather than pointers. This way there is only a
single pointer to the buffer, and nothing needs readjusting after a
realloc. (You may note that some uses of token_start/token_end didn't
need to be changed to add in "*buf +" - that's because there ended up
being a +*buf and -*buf which canceled each other out).

DV gets the credit for finding this bug and pointing out the valgrind
report.

fb68e28304 tests: dynamically replace dnsmasq path
The path to the dnsmasq binary can be configured while in the test data
the path is hard-coded to /usr/bin/. This break the test suite if a the
binary is located in a different location, like /usr/local/sbin/.

Replace the hard coded path in the test data by a token, which is
dynamically replaced in networkxml2argvtest with the configured path
after the test data has been loaded.

(Another option would have been to modify configure.ac to generate the
 test data during configure, but I do not know of an easy way do trick
 configure into mass-generate those test files without listing every
 single one, which I consider less flexible.)

- unit-test the unit-test:
  #include <assert.h>
  #define TEST(in,token,rep,out) { char *buf = strdup(in); assert(!replaceTokens(&buf, token, rep) && !strcmp(buf, out)); free(buf); }

64b8925c37 daemon: Fix crash in virTypedParameterArrayClear
Daemon uses the following pattern when dispatching APIs with typed
parameters:

    VIR_ALLOC_N(params, nparams);
    virDomain*(dom, params, &nparams, flags);
    virTypedParameterArrayClear(params, nparams);

In case nparams was originally set to 0, virDomain* API would fill it
with the number of typed parameters it can provide and we would use this
number (rather than zero) to clear params. Because VIR_ALLOC* returns
non-NULL pointer even if size is 0, the code would end up walking
through random memory. If we were lucky enough and the memory contained
7 (VIR_TYPED_PARAM_STRING) at the right place, we would try to free a
random pointer and crash.

Let's make sure params stays NULL when nparams is 0.

1a6bad7108 command: avoid double close bugs
KAMEZAWA Hiroyuki reported a nasty double-free bug when virCommand
is used to convert a string into input to a child command.  The
problem is that the poll() loop of virCommandProcessIO would close()
the write end of the pipe in order to let the child see EOF, then
the caller virCommandRun() would also close the same fd number, with
the second close possibly nuking an fd opened by some other thread
in the meantime.  This in turn can have all sorts of bad effects.

The bug has been present since the introduction of virCommand in
commit f16ad06f.

This is based on his first attempt at a patch, at
https://bugzilla.redhat.com/show_bug.cgi?id=823716

b0200c81ec xen: do not use ioemu type for any emulated NIC
When using the xm/xend stack to manage instances there is a bug
that causes the emulated interfaces to be unusable when the vif
config contains type=ioemu.

The current code already has a special quirk to not use this
keyword if no specific model is given for the emulated NIC
(defaulting to rtl8139).
Essentially it works because regardless of the type argument,i
the Xen stack always creates emulated and paravirt interfaces and
lets the guest decide which one to use. So neither xl nor xm stack
actually require the type keyword for emulated NICs.

8213166b92 xend_internal: Use domain/status for shutdown check
On newer xend (v3.x and after) there is no state and domid reported
for inactive domains. When initially creating connections this is
handled in various places by assigning domain->id = -1.
But once an instance has been running, the id is set to the current
domain id. And it does not change when the instance is shut down.
So when querying the domain info, the hypervisor driver, which gets
asked first will indicate it cannot find information, then the
xend driver is asked and will set the status to NOSTATE because it
checks for the -1 domain id.
Checking domain/status for 0 seems to be more reliable for that.

One note: I am not sure whether the domain->id also should get set
back to -1 whenever any sub-driver thinks the instance is no longer
running.

abf4ab4827 fdstream: Add internal callback on stream close
This patch adds another callback to a FDstream object. The original
callback is used by the daemon stream driver to handle events.

This callback is called if and only if the stream is about to be closed.
This might be used to handle cleanup steps after a fdstream exits. This
will be used later on in ensuring mutually exclusive access to consoles.

* src/fdstream.c:
        - emit the callback, when stream is being closed
        - add data structures needed to handle the callback
        - add function to register callback
* src/fdstream.h:

so this event callback is necessary in order to enable a daemon to abort
a stream in such a way that the client will see the change.

silently, rather than raising an error in the RPC layer.

208d5836c8 Fix synchronous reading of stream data
commit 984840a2c2 removed the
notification of waiting calls when VIR_NET_CONTINUE messages
arrive. This was to fix the case of a virStreamAbort() call
being prematurely notified of completion.

The problem is that sometimes there are dummy calls from a
virStreamRecv() call waiting that *do* need to be notified.

These dummy calls should have a status VIR_NET_CONTINUE. So
re-add the notification upon VIR_NET_CONTINUE, but only if
the waiter also has a status of VIR_NET_CONTINUE.

3cbb1385e9 Install API XML desc to a standard location
Language bindings may well want to use the libvirt-api.xml and
libvirt-qemu-api.xml files to either auto-generate themselves,
or sanity check the manually written bindings for completeness.
Currently these XML files are not installed as standard, merely
ending up as a %doc file in the RPM.

This changes them to be installed into $prefix/share/libvirt/apis/
The *-refs.xml files are not installed, since those are only
useful during generation of the online API doc files.

The pkg-config file is enhanced so that you can query the install
location of the API files. eg

  # pkg-config --variable=libvirt_qemu_api libvirt

Every now & then, with parallel builds, we get a failure to

is because we get 2 instances of the generator running at
once.

We already list hvsupport.html.in in BUILT_SOURCES but this
was not working. It turns out the flaw is that we were
adding deps to the 'all:' target instead of the 'all-am:'
target. BUILT_SOURCES is a dep of 'all', so any custom
targets written in Makefile.am must use 'all-am:' so that
they don't get run until BUILT_SOURCES are completely

643ac7203a tests: avoid test failure on rawhide gnutls
I hit a VERY weird testsuite failure on rawhide, which included
_binary_ output to stderr, followed by a hang waiting for me
to type something! (Here, using ^@ for NUL):

$ ./commandtest
TEST: commandtest

.8^@^@^@8^@^@^@^A^@^@^@^Bay^A^@^@^@)PRIVATE-GNOME-KEYRING-PKCS11-PROTOCOL-V-1

I finally traced it to the fact that gnome-keyring, called via
gnutls_global_init which is turn called by virNetTLSInit, opens
an internal fd that it expects to communicate to via a
pthread_atfork handler (never mind that it violates POSIX by
using non-async-signal-safe functions in that handler:
https://bugzilla.redhat.com/show_bug.cgi?id=772320).

Our problem stems from the fact that we pulled the rug out from
under the library's expectations by closing an fd that it had
just opened.  While we aren't responsible for fixing the bugs
in that pthread_atfork handler, we can at least avoid the bugs
by not closing the fd in the first place.

e11aa0262b storage: Fix any VolLookupByPath if we have an empty logical pool
On F16 at least, empty volume groups don't have a directory under /dev.
The directory only appears once a logical volume is created.

This tickles some behavior in BackendStablePath which ends with
libvirt sleeping for 5 seconds while waiting for the directory to appear.
This causes all sorts of problems for the virStorageVolLookupByPath API
which virtinst uses, even if trying to resolve a path that is independent
of the logical pool.

In reality we don't even need to do that checking since logical pools
always have a stable target path. Short circuit the polling in that
case.

f0ba1c096a spec: make it easier to autoreconf when building rpm
Over time, Fedora and RHEL RPMs have often backported upstream
patches that touched configure.ac and/or Makefile.am; this

Making this a one-liner spec tweak will make it easier for future
backports to pull patches without having to find all the places
to touch to properly use the autotools.  Meanwhile, there have been
historical instances where an update in the autotools caused FTBFS
situations, so this is not on by default.

One of the xml tests in the test suite was created using a

valid for Fedora builds of qemu). Although strictly speaking it's not
necessary to replace it with an actual supported qemu machine type
(since the xml in question is never actually sent to qemu), this patch
changes it to the actually-supported "pc-0.13" just for general
tidiness. (Also, on some Fedora builds which contain a special patch
to rid the world of "fedora-13", having it mentioned in the test suite
will cause make check to fail.)

762801607a network: don't add iptables rules for externally managed networks
This patch addresses https://bugzilla.redhat.com/show_bug.cgi?id=760442

When a network has any forward type other than route, nat or none, the
network configuration should be done completely external to libvirt -
libvirt only uses these types to allow configuring guests in a manner
that isn't tied to a specific host (all the host-specific information,
in particular interface names, port profile data, and bandwidth
configuration is in the network definition, and the guest
configuration only references it).

Due to a bug in the bridge network driver, libvirt was adding iptables
rules for networks with forward type='bridge' etc. any time libvirtd
was restarted while one of these networks was active.

This patch eliminates that error by only "reloading" iptables rules if
forward type is route, nat, or none.

d20a6240b3 spec: fix logic bug in deciding to turn on cgconfig

Commit ecd8725 tried to silence a spurious warning on the initial
libvirt install, and commit ba6cbb1 tried to fix up the logic to the
correct Fedora version, but the warning was still present due to a
logic bug: since %{fedora} and %{rhel} are never simulatanously
set, then 0%{rhel} <= 6 made the %if always true.  Checking for
minimum versions (via >=) is okay, but checking for maximum versions
(via <=) requires a prerequisite test that the platform being tested
is non-zero.

Also fix a bogus setting of with_libxl (although we previously
hard-code with_libxl to 0 for rhel earlier in the file, so this
was not as severe a bug).

f2b5c5ff22 spec: mark directories in /var/run as ghosts
We have several directories that are created on the fly, and which
only contain state relevant to a running libvirtd process (all
located in /var/run).  Since the directories are created as needed,
and make no sense without a running libvirtd, we want them deleted
if libvirt is uninstalled.  And in F15 and newer, /var/run is on
tmpfs (forcing us to recreate on the fly); which means that someone
trying to verify a complete rpm will fail if the directory does not
currently exist because libvirtd has not been started since boot.
The solution, then, is to mark the directories as %ghost, so that
rpm knows that we own them and will clean it up if libvirt is
uninstalled, but will no longer create the directory for us at
install, nor complain at verify time if the directory does not exist.

See https://bugzilla.redhat.com/show_bug.cgi?id=656611.

2ce01ba20f Add internal APIs for dealing with time
The logging APIs need to be able to generate formatted timestamps
using only async signal safe functions. This rules out using
gmtime/localtime/malloc/gettimeday(!) and much more.

Introduce a new internal API which is async signal safe.

  virTimeMillisNowRaw replacement for gettimeofday. Uses clock_gettime
                      where available, otherwise falls back to the unsafe
                      gettimeofday

  virTimeFieldsNowRaw  replacements for gmtime(), convert a timestamp
  virTimeFieldsThenRaw into a broken out set of fields. No localtime()
                       replacement is provided, because converting to
                       local time is not practical with only async signal
                       safe APIs.

  virTimeStringNowRaw  replacements for strftime() which print a timestamp
  virTimeStringThenRaw into a string, using a pre-determined format, with

776124e6f0 qemu: make PCI multifunction support more manual
When support for was added for PCI multifunction cards (in commit
9f8baf, first included in libvirt 0.9.3), it was done by always
turning on the multifunction bit for all PCI devices. Since that time
it has been realized that this is not an ideal solution, and that the
multifunction bit must be selectively turned on. For example, see

  https://bugzilla.redhat.com/show_bug.cgi?id=728174

and the discussion before and after

  https://www.redhat.com/archives/libvir-list/2011-September/msg01036.html

This patch modifies multifunction support so that the multifunction=on
option is only added to the qemu commandline for a device if its PCI
<address> definition has the attribute "multifunction='on'", e.g.:

  <address type='pci' domain='0x0000' bus='0x00'
           slot='0x04' function='0x0' multifunction='on'/>

In practice, the multifunction bit should only be turned on if
function='0' AND other functions will be used in the same slot - it
usually isn't needed for functions 1-7 (although there are apparently
some exceptions, e.g. the Intel X53 according to the QEMU source
code), and should never be set if only function 0 will be used in the
slot. The test cases have been changed accordingly to illustrate.

With this patch in place, if a user attempts to assign multiple
functions in a slot without setting the multifunction bit for function
0, libvirt will issue an error when the domain is defined, and the
define operation will fail. In the future, we may decide to detect
this situation and automatically add multifunction=on to avoid the
error; even then it will still be useful to have a manual method of
turning on multifunction since, as stated above, there are some
devices that excpect it to be turned on for all functions in a slot.

A side effect of this patch is that attempts to use the same PCI
address for two different devices will now log an error (previously
this would cause the domain define operation to fail, but there would
be no log message generated). Because the function doing this log was
almost completely rewritten, I didn't think it worthwhile to make a
separate patch for that fix (the entire patch would immediately be
obsoleted).

d20f5421a9 conf: remove unused VIR_ENUM_DECL
While adding a new enum, I noticed a VIR_ENUM_DECL for a type that
doesn't exist. There is also of course no matching VIR_ENUM_IMPL for
it.

64eadd9a7b spec: F15 still uses cgconfig, RHEL lacks hyperv
Commit ecd8725c dropped attempts to probe the cgconfig service on
new enough Fedora where systemd took over that aspect of the system,
but mistakenly used F14 instead of F15 as the cutoff point.

https://bugzilla.redhat.com/show_bug.cgi?id=741358

Also, RHEL does not include HyperV support yet.

* libvirt.spec.in (with_cgconfig): Check cgconfig service in F15.
(%{?rhel}): Provide default for with_hyperv.

* src/virsh.c: use 'double' instead of 'float' when calculating
'CPU time' field for dominfo command, to ensure no unnecessary
'CPU time' field for dominfo command, to ensure no unneccessary
loss of precision converting from nanoseconds to seconds.

git diff > libvirt-myfeature.patch
However, the usual workflow of libvirt developer is:
git checkout master
git pull
git checkout -t origin -b workbranch
Hack, committing any changes along the way
Then, when you want to post your patches:
git pull --rebase
(fix any conflicts)
git send-email --cover-letter --no-chain-reply-to --annotate --to=libvir-list@redhat.com master
For a single patch you can omit "--cover-letter", but series of a two or more
patches needs a cover letter. If you get tired of typing
"--to=libvir-list@redhat.com" designation you can set it in git config:
git config sendemail.to libvir-list@redhat.com
Please follow this as close as you can, especially the rebase and git
send-email part, as it makes life easier for other developers to review your
patch set. One should avoid sending patches as attachments, but rather send
them in email body along with commit message. If a developer is sending
another version of the patch (e.g. to address review comments), he is advised
to note differences to previous versions after the "---" line in the patch so
that it helps reviewers but doesn't become part of git history. Moreover, such
patch needs to be prefixed correctly with "--subject-prefix=PATCHv2" appended
to "git send-email" (substitute "v2" with the correct version if needed
though).
(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. Moreover, please keep in mind that it's
required to be able to compile cleanly after each patch. A feature does not
have to work until the end of a series, as long as intermediate patches don't
cause test-suite failures.
sequence of patches fits together.
(4) Make sure your patches apply against libvirt GIT. Developers only follow GIT
and don't care much about released versions.

# Keepalive protocol:
# This allows libvirtd to detect broken client connections or even
# dead client. A keepalive message is sent to a client after
# keepalive_interval seconds of inactivity to check if the client is
# still responding; keepalive_count is a maximum number of keepalive
# messages that are allowed to be sent to the client without getting
# any response before the connection is considered broken. In other
# words, the connection is automatically closed approximately after
# keepalive_interval * (keepalive_count + 1) seconds since the last
# message received from the client. If keepalive_interval is set to
# -1, libvirtd will never send keepalive requests; however clients
# can still send them and the deamon will send responses. When
# keepalive_count is set to 0, connections will be automatically
# closed after keepalive_interval seconds of inactivity without
# sending any keepalive messages.
#
#keepalive_interval = 5
#keepalive_count = 5

# If set to 1, libvirtd will refuse to talk to clients that do not
# support keepalive protocol. Defaults to 0.

<h2><a name="Auth_client_config">Client configuration</a></h2>
<p>
When connecting to a remote hypervisor which requires authentication,
most libvirt applications will prompt the user for the credentials. It is
also possible to provide a client configuration file containing all the
authentication credentials, avoiding any interaction. Libvirt will look
for the authentication file using the following sequence:
</p>
<ol>
<li>The file path specified by the $LIBVIRT_AUTH_FILE environment
variable.</li>
<li>The file path specified by the "authfile=/some/file" URI
query parameter</li>
<li>The file $XDG_CONFIG_DIR/libvirt/auth.conf</li>
<li>The file /etc/libvirt/auth.conf</li>
</ol>
<p>
The auth configuration file uses the traditional <code>".ini"</code>
style syntax. There are two types of groups that can be present in
the config. First there are one or more <strong>credential</strong>
sets, which provide the actual authentication credentials. The keys
within the group may be:
</p>
<ul>
<li><code>username</code>: the user login name to act as. This
is relevant for ESX, Xen, HyperV and SSH, but probably not
the one you want to libvirtd with SASL.</li>
<li><code>authname</code>: the name to authorize as. This is
what is commonly required for libvirtd with SASL.</li>
<li><code>password</code>: the secret password</li>
<li><code>realm</code>: the domain realm for SASL, mostly
unused</li>
</ul>
<p>
Each set of credentials has a name, which is part of the group
entry name. Overall the syntax is
</p>
<pre>
[credentials-$NAME]
credname1=value1
credname2=value2</pre>
<p>
For example, to define two sets of credentials used for production
and test machines, using libvirtd, and a further ESX server for dev:
</p>
<pre>
[credentials-test]
authname=fred
password=123456
[credentials-prod]
authname=bar
password=letmein
[credentials-dev]
username=joe
password=hello</pre>
<p>
The second set of groups provide mappings of credentials to
specific machine services. The config file group names compromise
the service type and host:
</p>
<pre>
[auth-$SERVICE-$HOSTNAME]
credentials=$CREDENTIALS</pre>
<p>
For example, following the previous example, here is how to
list some machines
</p>
<pre>
[auth-libvirt-test1.example.com]
credentials=test
[auth-libvirt-test2.example.com]
credentials=test
[auth-libvirt-demo3.example.com]
credentials=test
[auth-libvirt-prod1.example.com]
credentials=prod
[auth-esx-dev1.example.com]
credentials=dev</pre>
<p>
The following service types are known to libvirt
</p>
<ol>
<li><code>libvirt</code> - used for connections to a libvirtd
server, which is configured with SASL auth</li>
<li><code>ssh</code> - used for connections to a Phyp server
over SSH</li>
<li><code>esx</code> - used for connections to an ESX or
VirtualCenter server</li>
<li><code>xen</code> - used for connections to a Xen Enterprise
sever using XenAPI</li>
</ol>
<p>
Applications using libvirt are free to use this same configuration
file for storing other credentials. For example, it can be used
to storage VNC or SPICE login credentials

It's always a good idea to file bug reports, as the process of
filing the report always makes it easier to describe the
problem, and the bug number provides a quick way of referring to
the problem. However, not everybody in the community pays
attention to bugzilla, so after you file a bug, asking questions
and submitting patches on <a href="contact.html">the libvirt
mailing lists</a> will increase your bug's visibility and
encourage people to think about your problem. Don't hesitate to
ask questions on the list, as others may know of existing
solutions or be interested in collaborating with you on finding
a solution. Patches are always appreciated, and it's likely
that someone else has the same problem you do!
</p>
<p>
If you decide to write code, though, before you begin please
read the <a href="hacking.html">contributor guidelines</a>,
especially the first point: "Discuss any large changes on the
mailing list first. Post patches early and listen to feedback."
Few development experiences are more discouraging than spending
a bunch of time writing a patch only to have someone point out a
better approach on list.

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. By default when
the <code>configure</code> script is run from within a GIT checkout, it
will turn on -Werror for builds. This can be disabled with --disable-werror,
but this is not recommended. To build &amp; install libvirt to your home
directory the following commands can be run:
templates using the <code>autogen.sh</code> command, passing the extra
arguments as for configure. As an example, to do a complete build and
install it into your home directory run:
</p>
<pre>
$ ./autogen.sh --prefix=$HOME/usr
$ ./autogen.sh --prefix=$HOME/usr --enable-compile-warnings=error
$ make
$ <b>sudo</b> make install</pre>
<p>
Be aware though, that binaries built with a custom prefix will not
interoperate with OS vendor provided binaries, since the UNIX socket
paths will all be different. To produce a build that is compatible
with normal OS vendor prefixes, use
</p>
<pre>
$ ./autogen.sh --system
$ make
</pre>
<p>
When doing this for day-to-day development purposes, it is recommended
not to install over the OS vendor provided binaries. Instead simply
run libvirt directly from the source tree. For example to run
a privileged libvirtd instance
</p>
<pre>
$ su -
# service libvirtd stop (or systemctl stop libvirtd.service)
# /home/to/your/checkout/daemon/libvirtd
</pre>
<p>
It is also possible to run virsh directly from the source tree
</p>
<pre>
$ ./tools/virsh ....
</pre>
<p>
A normal configuration of libvirt will build hypervisor drivers
as loadable modules. When running from a non-installed source
tree, libvirtd will attempt to find the modules from the same
source tree. If this is not possible though, you can explicitly
set <code>LIBVIRT_DRIVER_DIR=/path/to/source/tree/src/.libs</code>

<h2><a name="qemucommand">Pass-through of arbitrary qemu
commands</a></h2>
<p>Libvirt provides an XML namespace and an optional
library <code>libvirt-qemu.so</code> for dealing specifically
with qemu. When used correctly, these extensions allow testing
specific qemu features that have not yet been ported to the
generic libvirt XML and API interfaces. However, they
are <b>unsupported</b>, in that the library is not guaranteed to
have a stable API, abusing the library or XML may result in
inconsistent state the crashes libvirtd, and upgrading either
qemu-kvm or libvirtd may break behavior of a domain that was
relying on a qemu-specific pass-through. If you find yourself
needing to use them to access a particular qemu feature, then
please post an RFE to the libvirt mailing list to get that
feature incorporated into the stable libvirt XML and API
interfaces.
</p>
<p>The library provides two
API: <code>virDomainQemuMonitorCommand</code>, for sending an
arbitrary monitor command (in either HMP or QMP format) to a
qemu guest (<span class="since">Since 0.8.3</span>),
and <code>virDomainQemuAttach</code>, for registering a qemu
domain that was manually started so that it can then be managed
by libvirtd (<span class="since">Since 0.9.4</span>).
</p>
<p>Additionally, the following XML additions allow fine-tuning of
the command line given to qemu when starting a domain
(<span class="since">Since 0.8.3</span>). In order to use the
XML additions, it is necessary to issue an XML namespace request
(the special <code>xmlns:<i>name</i></code> attribute) that
pulls in <code>http://libvirt.org/schemas/domain/qemu/1.0</code>;
typically, the namespace is given the name
of <code>qemu</code>. With the namespace in place, it is then
possible to add an element <code>&lt;qemu:commandline&gt;</code>
under <code>driver</code>, with the following sub-elements
repeated as often as needed:
<dl>
<dt><code>qemu:arg</code></dt>
<dd>Add an additional command-line argument to the qemu
process when starting the domain, given by the value of the
attribute <code>value</code>.
</dd>
<dt><code>qemu:env</code></dt>
<dd>Add an additional environment variable to the qemu
process when starting the domain, given with the name-value
pair recorded in the attributes <code>name</code>
and optional <code>value</code>.</dd>
</dl>
<p>Example:</p><pre>
&lt;domain type='qemu' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'&gt;

This network facilitates PCI Passthrough of a network
device. A network device is chosen from the interface
pool and directly assigned to the guest using generic
device passthrough, after first optionally setting the
device's MAC address and vlan tag to the configured value,
and optionally associating the device with an 802.1Qbh
capable switch using a <code>&lt;virtualport&gt;</code>
element. Note that - due to limitations in standard
single-port PCI ethernet card driver design - only SR-IOV
(Single Root I/O Virtualization) virtual function (VF)
devices can be assigned in this manner; to assign a
standard single-port PCI or PCIe ethernet card to a guest,
use the traditional <code>&lt; hostdev&gt;</code> device
definition. <span class="since"> Since 0.10.0</span>
<p>Note that this "intelligent passthrough" of network
devices is very similar to the functionality of a
standard <code>&lt; hostdev&gt;</code> device, the
difference being that this method allows specifying a MAC
address, vlan tag, and <code>&lt;virtualport &gt;</code>
for the passed-through device. If these capabilities are
not required, if you have a standard single-port PCI,
PCIe, or USB network card that doesn't support SR-IOV (and
hence would anyway lose the configured MAC address during
reset after being assigned to the guest domain), or if you
are using a version of libvirt older than 0.10.0, you
should use a standard
<code>&lt;hostdev&gt;</code> device definition in the
domain's configuration to assign the device to the guest
instead of defining an <code>&lt;interface

with <code>&lt;forward mode='hostdev'/&gt;</code>.

host devices that can be handed to guests via passthrough as

<h3><a name="nwfconceptschains">Filtering chains</a></h3>
<p>
Filtering rules are organized in filter chains. These chains can be
thought of as having a tree structure with packet
filtering rules as entries in individual chains (branches). <br>
Packets start their filter evaluation in the <code>root</code> chain
and can then continue their evaluation in other chains, return from
those chains back into the <code>root</code> chain or be
dropped or accepted by a filtering rule in one of the traversed chains.
<br/>
Libvirt's network filtering system automatically creates individual
<code>root</code> chains for every virtual machine's network interface
on which the user chooses to activate traffic filtering.
The user may write filtering rules that are either directly instantiated
in the <code>root</code> chain or may create protocol-specific
filtering chains for efficient evaluation of protocol-specific rules.
The following chains exist:
</p>
<ul>
<li>root</li>
<li>mac <span class="since">(since 0.9.8)</span></li>
<li>stp (spanning tree protocol)
<span class="since">(since 0.9.8)</span></li>
<li>vlan (802.1Q) <span class="since">(since 0.9.8)</span></li>
<li>arp, rarp</li>
<li>ipv4</li>
<li>ipv6</li>
</ul>
<p>
<span class="since">Since 0.9.8</span> multiple chains evaluating the
<code>mac</code>, <code>stp</code>, <code>vlan</code>,
<code>arp</code>, <code>rarp</code>, <code>ipv4</code>, or
<code>ipv6</code> protocol can be created using
the protocol name only as a prefix in the chain's name. This for
examples allows chains with names <code>arp-xyz</code> or
<code>arp-test</code> to be specified and have ARP protocol packets
evaluated in those chains.
<br/><br/>
The following filter shows an example of filtering ARP traffic
in the <code>arp</code> chain.
</p>
<pre>
&lt;filter name='no-arp-spoofing' chain='arp' priority='-500'&gt;
&lt;uuid&gt;f88f1932-debf-4aa1-9fbe-f10d3aa4bc95&lt;/uuid&gt;
&lt;rule action='drop' direction='out' priority='300'&gt;
&lt;mac match='no' srcmacaddr='$MAC'/&gt;
&lt;/rule&gt;
&lt;rule action='drop' direction='out' priority='350'&gt;
&lt;arp match='no' arpsrcmacaddr='$MAC'/&gt;
&lt;/rule&gt;
&lt;rule action='drop' direction='out' priority='400'&gt;
&lt;arp match='no' arpsrcipaddr='$IP'/&gt;
&lt;/rule&gt;
&lt;rule action='drop' direction='in' priority='450'&gt;
&lt;arp opcode='Reply'/&gt;
&lt;arp match='no' arpdstmacaddr='$MAC'/&gt;
&lt;/rule&gt;
&lt;rule action='drop' direction='in' priority='500'&gt;
&lt;arp match='no' arpdstipaddr='$IP'/&gt;
&lt;/rule&gt;
&lt;rule action='accept' direction='inout' priority='600'&gt;
&lt;arp opcode='Request'/&gt;
&lt;/rule&gt;

&lt;arp opcode='Reply'/&gt;
&lt;/rule&gt;
&lt;rule action='drop' direction='inout' priority='1000'/&gt;
&lt;/filter&gt;
</pre>
<p>
The consequence of putting ARP-specific rules in the <code>arp</code>
chain, rather than for example in the <code>root</code> chain, is that
packets for any other protocol than ARP do not need to be evaluated by
ARP protocol-specific rules. This improves the efficiency
of the traffic filtering. However, one must then pay attention to only
put filtering rules for the given protocol into the chain since
any other rules will not be evaluated, i.e., an IPv4 rule will not
be evaluated in the ARP chain since no IPv4 protocol packets will
traverse the ARP chain.
<br/><br/>
</p>
<h3><a name="nwfconceptschainpriorities">Filtering chain priorities</a></h3>
<p>
All chains are connected to the <code>root</code> chain. The order in
which those chains are accessed is influenced by the priority of the
chain. The following table shows the chains that can be assigned a
priority and their default priorities.
</p>
<table class="top_table">

<p>
A chain with a lower priority value is accessed before one with a
higher value.
<br><br>
<span class="since">Since 0.9.8</span> the above listed chains
can be assigned custom priorities by writing a value in the
range [-1000, 1000] into the priority (XML) attribute in the filter
node. The above example filter shows the default priority of -500

that are expected for each XML attribute are shown
below.
<br/><br/>
<span class="since">Since 0.9.8</span> variables can contain lists of
elements, e.g., the variable <code>IP</code> can contain multiple IP
addresses that are valid on a particular interface. The notation for
providing multiple elements for the IP variable is:
</p>
<pre>
...
&lt;devices&gt;
&lt;interface type='bridge'&gt;
&lt;mac address='00:16:3e:5d:c7:9e'/&gt;
&lt;filterref filter='clean-traffic'&gt;
&lt;parameter name='IP' value='10.0.0.1'/&gt;
&lt;parameter name='IP' value='10.0.0.2'/&gt;
&lt;parameter name='IP' value='10.0.0.3'/&gt;
&lt;/filterref&gt;
&lt;/interface&gt;
&lt;/devices&gt;
...</pre>
<p>
This then allows filters to enable multiple IP addresses
per interface. Therefore, with the list
of IP address shown above, the following rule will create 3
individual filtering rules, one for each IP address.
</p>
<pre>
...
&lt;rule action='accept' direction='in' priority='500'&gt;
&lt;tcp srpipaddr='$IP'/&gt;
&lt;/rule&gt;
...
</pre>
<p>
<span class="since">Since 0.9.10</span> it is possible to access
individual elements of a variable holding a list of elements.
A filtering rule like the following accesses the 2nd element
of the variable DSTPORTS.
</p>
<pre>
...
&lt;rule action='accept' direction='in' priority='500'&gt;
&lt;udp dstportstart='$DSTPORTS[1]'/&gt;
&lt;/rule&gt;
...
</pre>
<p>
<span class="since">Since 0.9.10</span> it is possible to create
filtering rules that instantiate all combinations of rules from
different lists using the notation of
<code>$VARIABLE[@&lt;iterator ID&gt;]</code>.
The following rule allows a virtual machine to
receive traffic on a set of ports, which are specified in DSTPORTS,
from the set of source IP address specified in SRCIPADDRESSES.
The rule generates all combinations of elements of the variable
DSTPORT with those of SRCIPADDRESSES by using two independent
iterators to access their elements.
</p>
<pre>
...
&lt;rule action='accept' direction='in' priority='500'&gt;
&lt;ip srcipaddr='$SRCIPADDRESSES[@1]' dstportstart='$DSTPORTS[@2]'/&gt;
&lt;/rule&gt;
...
</pre>
<p>
In an example we assign concrete values to SRCIPADDRESSES and DSTPORTS
</p>
<pre>
SRCIPADDRESSES = [ 10.0.0.1, 11.1.2.3 ]
DSTPORTS = [ 80, 8080 ]
</pre>
<p>
Accessing the variables using $SRCIPADDRESSES[@1] and $DSTPORTS[@2] would
then result in all combinations of addresses and ports being created:
</p>
<pre>
10.0.0.1, 80
10.0.0.1, 8080
11.1.2.3, 80
11.1.2.3, 8080
</pre>
<p>
Accessing the same variables using a single iterator, for example by using
the notation $SRCIPADDRESSES[@1] and $DSTPORTS[@1], would result in
parallel access to both lists and result in the following combinations:
</p>
<pre>
10.0.0.1, 80
11.1.2.3, 8080
</pre>
<p>
Further, the notation of $VARIABLE is short-hand for $VARIABLE[@0]. The
former notation always assumes the iterator with Id '0'.

<h3><a name="nwfelemsRulesAdvIPAddrDetection">Automatic IP address detection</a></h3>
<p>
The detection of IP addresses used on a virtual machine's interface
is automatically activated if the variable <code>IP</code> is referenced
but no value has been assigned to it.
<span class="since">Since 0.9.13</span>
the variable <code>CTRL_IP_LEARNING</code> can be used to specify
the IP address learning method to use. Valid values are <code>any</code>,
<code>dhcp</code>, or <code>none</code>.
<br/><br/>
The value <code>any</code> means that libvirt may use any packet to
determine the address in use by a virtual machine, which is the default
behavior if the variable <code>CTRL_IP_LEARNING</code> is not set. This method
will only detect a single IP address on an interface.
Once a VM's IP address has been detected, its IP network traffic
will be locked to that address, if for example IP address spoofing
is prevented by one of its filters. In that case the user of the VM
will not be able to change the IP address on the interface inside
the VM, which would be considered IP address spoofing.
When a VM is migrated to another host or resumed after a suspend operation,
the first packet sent by the VM will again determine the IP address it can
use on a particular interface.
<br/><br>
A value of <code>dhcp</code> specifies that libvirt should only honor DHCP
server-assigned addresses with valid leases. This method supports the detection
and usage of multiple IP address per interface.
When a VM is resumed after a suspend operation, still valid IP address leases
are applied to its filters. Otherwise the VM is expected to again use DHCP to obtain new
IP addresses. The migration of a VM to another physical host requires that
the VM again runs the DHCP protocol.
<br/><br/>
Use of <code>CTRL_IP_LEARNING=dhcp</code> (DHCP snooping) provides additional
anti-spoofing security, especially when combined with a filter allowing
only trusted DHCP servers to assign addresses. To enable this, set the
variable <code>DHCPSERVER</code> to the IP address of a valid DHCP server
and provide filters that use this variable to filter incoming DHCP responses.
<br/><br/>
When DHCP snooping is enabled and the DHCP lease expires,
the VM will no longer be able to use the IP address until it acquires a
new, valid lease from a DHCP server. If the VM is migrated, it must get
a new valid DHCP lease to use an IP address (e.g., by
bringing the VM interface down and up again).
<br/><br/>
Note that automatic DHCP detection listens to the DHCP traffic
the VM exchanges with the DHCP server of the infrastructure. To avoid
denial-of-service attacks on libvirt, the evaluation of those packets
is rate-limited, meaning that a VM sending an excessive number of DHCP
packets per second on an interface will not have all of those packets
evaluated and thus filters may not get adapted. Normal DHCP client
behavior is assumed to send a low number of DHCP packets per second.
Further, it is important to setup appropriate filters on all VMs in
the infrastructure to avoid them being able to send DHCP
packets. Therefore VMs must either be prevented from sending UDP and TCP
traffic from port 67 to port 68 or the <code>DHCPSERVER</code>
variable should be used on all VMs to restrict DHCP server messages to
only be allowed to originate from trusted DHCP servers. At the same
time anti-spoofing prevention must be enabled on all VMs in the subnet.
<br/><br/>
If <code>CTRL_IP_LEARNING</code> is set to <code>none</code>, libvirt does not do
IP address learning and referencing <code>IP</code> without assigning it an
explicit value is an error.
<br/><br/>
The following XML provides an example for the activation of IP address learning
using the DHCP snooping method:
</p>
<pre>
&lt;interface type='bridge'&gt;
&lt;source bridge='virbr0'/&gt;
&lt;filterref filter='clean-traffic'&gt;
&lt;parameter name='CTRL_IP_LEARNING' value='dhcp'/&gt;
&lt;/filterref&gt;

<p>
In case a network filter references the variable
<i>IP</i> and no variable was defined in any higher layer
references to the filter, IP address detection will automatically
be started when the filter is to be instantiated (VM start, interface
hotplug event). Only IPv4
addresses can be detected and only a single IP address
legitimately in use by a VM on a single interface will be detected.
In case a VM was to use multiple IP address on a single interface
(IP aliasing),
the IP addresses would have to be provided explicitly either
in the network filter itself or as variables used in attributes'
values. These
variables must then be defined in a higher level reference to the filter
and each assigned the value of the IP address that the VM is expected
to be using.
Different IP addresses in use by multiple interfaces of a VM
(one IP address each) will be independently detected.

Once a VM's IP address has been detected, its IP network traffic
may be locked to that address, if for example IP address spoofing
is prevented by one of its filters. In that case the user of the VM

<h3><a name="nwflimitsvlan">VLAN filtering on Linux</a></h3>
<p>
VLAN (802.1Q) packets, if sent by a virtual machine, cannot be filtered
with rules for protocol IDs <code>arp</code>, <code>rarp</code>,
<code>ipv4</code> and <code>ipv6</code> but only
with protocol IDs <code>mac</code> and <code>vlan</code>. Therefore,
the example filter <code>clean-traffic</code> will not work as expected.

<p>Please follow this as close as you can, especially the rebase and
git send-email part, as it makes life easier for other developers to
review your patch set. One should avoid sending patches as attachments,
but rather send them in email body along with commit message. If a
developer is sending another version of the patch (e.g. to address
review comments), he is advised to note differences to previous
versions after the <code>---</code> line in the patch so that it helps
reviewers but doesn't become part of git history. Moreover, such patch
needs to be prefixed correctly with
<code>--subject-prefix=PATCHv2</code> appended to <code>git

version if needed though).</p>

<h1>Guest migration</h1>
<ul id="toc"></ul>
<p>
Migration of guests between hosts is a complicated problem with many possible
solutions, each with their own positive and negative points. For maximum
flexibility of both hypervisor integration, and adminsitrator deployment,
libvirt implements several options for migration.
</p>
<h2><a id="transport">Network data transports</a></h2>
<p>
There are two options for the data transport used during migration, either
the hypervisor's own <strong>native</strong> transport, or <strong>tunnelled</strong>
over a libvirtd connection.
</p>
<h3><a id="transportnative">Hypervisor native transport</a></h3>
<p>
<em>Native</em> data transports may or may not support encryption, depending
on the hypervisor in question, but will typically have the lowest computational costs
by minimising the number of data copies involved. The native data transports will also
require extra hypervisor-specific network configuration steps by the administrator when
deploying a host. For some hypervisors, it might be necessary to open up a large range
of ports on the firewall to allow multiple concurrent migration operations.
</p>
<p>
<img class="diagram" src="migration-native.png" alt="Migration native path">
</p>
<h3><a id="transporttunnel">libvirt tunnelled transport</a></h3>
<p>
<em>Tunnelled</em> data transports will always be capable of strong encryption
since they are able to leverage the capabilities built in to the libvirt RPC protocol.
The downside of a tunnelled transport, however, is that there will be extra data copies
involved on both the source and destinations hosts as the data is moved between libvirtd
and the hypervisor. This is likely to be a more significant problem for guests with
very large RAM sizes, which dirty memory pages quickly. On the deployment side, tunnelled
transports do not require any extra network configuration over and above what's already
required for general libvirtd <a href="remote.html">remote access</a>, and there is only
need for a single port to be open on the firewall to support multiple concurrent
migration operations.
</p>
<p>
<img class="diagram" src="migration-tunnel.png" alt="Migration tunnel path">
</p>
<h2><a id="flow">Communication control paths/flows</a></h2>
<p>
Migration of virtual machines requires close co-ordination of the two
hosts involved, as well as the application invoking the migration,
which may be on the source, the destination, or a third host.
</p>
<h3><a id="flowmanageddirect">Managed direct migration</a></h3>
<p>
With <em>managed direct</em> migration, the libvirt client process
controls the various phases of migration. The client application must
be able to connect and authenticate with the libvirtd daemons on both
the source and destination hosts. There is no need for the two libvirtd
daemons to communicate with each other. If the client application
crashes, or otherwise loses its connection to libvirtd during the
migration process, an attempt will be made to abort the migration and
restart the guest CPUs on the source host. There may be scenarios
where this cannot be safely done, in which cases the guest will be
left paused on one or both of the hosts.
</p>
<p>
<img class="diagram" src="migration-managed-direct.png" alt="Migration direct, managed">
</p>
<h3><a id="flowpeer2peer">Managed peer to peer migration</a></h3>
<p>
With <em>peer to peer</em> migration, the libvirt client process only
talks to the libvirtd daemon on the source host. The source libvirtd
daemon controls the entire migration process itself, by directly
connecting the destination host libvirtd. If the client application crashes,
or otherwise loses its connection to libvirtd, the migration process
will continue uninterrupted until completion. Note that the
source libvirtd uses its own credentials (typically root) to
connect to the destination, rather than the credentials used
by the client to connect to the source; if these differ, it is
common to run into a situation where a client can connect to the
destination directly but the source cannot make the connection to
set up the peer-to-peer migration.
</p>
<p>
<img class="diagram" src="migration-managed-p2p.png" alt="Migration peer-to-peer">
</p>
<h3><a id="flowunmanageddirect">Unmanaged direct migration</a></h3>
<p>
With <em>unmanaged direct</em> migration, neither the libvirt client
or libvirtd daemon control the migration process. Control is instead
delegated to the hypervisor's over management services (if any). The
libvirt client merely initiates the migration via the hypervisor's
management layer. If the libvirt client or libvirtd crash, the
migration process will continue uninterrupted until completion.
</p>
<p>
<img class="diagram" src="migration-unmanaged-direct.png" alt="Migration direct, unmanaged">
</p>
<h2><a id="security">Data security</a></h2>
<p>
Since the migration data stream includes a complete copy of the guest
OS RAM, snooping of the migration data stream may allow compromise
of sensitive guest information. If the virtualization hosts have
multiple network interfaces, or if the network switches support
tagged VLANs, then it is very desirable to separate guest network
traffic from migration or management traffic.
</p>
<p>
In some scenarios, even a separate network for migration data may
not offer sufficient security. In this case it is possible to apply
encryption to the migration data stream. If the hypervisor does not
itself offer encryption, then the libvirt tunnelled migration
facility should be used.
</p>
<h2><a id="uris">Migration URIs</a></h2>
<p>
Initiating a guest migration requires the client application to
specify up to three URIs, depending on the choice of control
flow and/or APIs used. The first URI is that of the libvirt
connection to the source host, where the virtual guest is
currently running. The second URI is that of the libvirt
connection to the destination host, where the virtual guest
will be moved to (and in peer-to-peer migrations, this is from
the perspective of the source, not the client). The third URI is
a hypervisor specific
URI used to control how the guest will be migrated. With
any managed migration flow, the first and second URIs are
compulsory, while the third URI is optional. With the
unmanaged direct migration mode, the first and third URIs are
compulsory and the second URI is not used.
</p>
<p>
Ordinarily management applications only need to care about the
first and second URIs, which are both in the normal libvirt
connection URI format. Libvirt will then automatically determine
the hypervisor specific URI, by looking up the target host's
configured hostname. There are a few scenarios where the management
application may wish to have direct control over the third URI.
</p>
<ol>
<li>The configured hostname is incorrect, or DNS is broken. If a
host has a hostname which will not resolve to match one of its
public IP addresses, then libvirt will generate an incorrect
URI. In this case the management application should specify the
hypervisor specific URI explicitly, using an IP address, or a
correct hostname.</li>
<li>The host has multiple network interaces. If a host has multiple
network interfaces, it might be desirable for the migration data
stream to be sent over a specific interface for either security
or performance reasons. In this case the management application
should specify the hypervisor specific URI, using an IP address
associated with the network to be used.</li>
<li>The firewall restricts what ports are available. When libvirt
generates a migration URI will pick a port number using hypervisor
specific rules. Some hypervisors only require a single port to be
open in the firewalls, while others require a whole range of port
numbers. In the latter case the management application may wish
to choose a specific port number outside the default range in order
to comply with local firewall policies</li>
</ol>
<h2><a id="config">Configuration file handling</a></h2>
<p>
There are two types of virtual machine known to libvirt. A <em>transient</em>
guest only exists while it is running, and has no configuration file stored
on disk. A <em>persistent</em> guest maintains a configuration file on disk
even when it is not running.
</p>
<p>
By default, a migration operation will not attempt to change any configuration
files that may be stored on either the source or destination host. It is the
administrator, or management application's, responsibility to manage distribution
of configuration files (if desired). It is important to note that the <code>/etc/libvirt</code>
directory <strong>MUST NEVER BE SHARED BETWEEN HOSTS</strong>. There are some
typical scenarios that might be applicable:
</p>
<ul>
<li>Centralized configuration files outside libvirt, in shared storage. A cluster
aware management application may maintain all the master guest configuration
files in a cluster filesystem. When attempting to start a guest, the config
will be read from the cluster FS and used to deploy a persistent guest.
For migration the configuration will need to be copied to the destination
host and removed on the original.
</li>
<li>Centralized configuration files outside libvirt, in a database. A data center
management application may not storage configuration files at all. Instead it
may generate libvirt XML on the fly when a guest is booted. It will typically
use transient guests, and thus not have to consider configuration files during
migration.
</li>
<li>Distributed configuration inside libvirt. The configuration file for each
guest is copied to every host where the guest is able to run. Upon migration
the existing config merely needs to be updated with any changes
</li>
<li>Ad-hoc configuration management inside libvirt. Each guest is tied to a
specific host and rarely migrated. When migration is required, the config
is moved from one host to the other.
</li>
</ul>
<p>
As mentioned above, libvirt will not touch configuration files during
migration by default. The <code>virsh</code> command has two flags to
influence this behaviour. The <code>--undefine-source</code> flag
will cause the configuration file to be removed on the source host
after a successful migration. The <code>--persist</code> flag will
cause a configuration file to be created on the destination host
after a successful migration. The following table summarizes the
configuration file handling in all possible state and flag
combinations.

<h2><a id="scenarios">Migration scenarios</a></h2>
<h3><a id="scenarionativedirect">Native migration, client to two libvirtd servers</a></h3>
<p>
At an API level this requires use of virDomainMigrate, without the
VIR_MIGRATE_PEER2PEER flag set. The destination libvirtd server
will automatically determine the native hypervisor URI for migration
based off the primary hostname. To force migration over an alternate
network interface the optional hypervisor specific URI must be provided
</p>
<pre>
syntax: virsh migrate GUESTNAME DEST-LIBVIRT-URI [HV-URI]
eg using default network interface
virsh migrate web1 qemu+ssh://desthost/system
virsh migrate web1 xen+tls://desthost/system
eg using secondary network interface
virsh migrate web1 qemu://desthost/system tcp://10.0.0.1/
virsh migrate web1 xen+tcp://desthost/system xenmigr:10.0.0.1/
</pre>
<p>
Supported by Xen, QEMU, VMWare and VirtualBox drivers
</p>
<h3><a id="scenarionativepeer2peer">Native migration, client to and peer2peer between, two libvirtd servers</a></h3>
<p>
virDomainMigrate, with the VIR_MIGRATE_PEER2PEER flag set,
using the libvirt URI format for the 'uri' parameter. The
destination libvirtd server will automatically determine
the native hypervisor URI for migration, based off the
primary hostname. The optional uri parameter controls how
the source libvirtd connects to the destination libvirtd,
in case it is not accessible using the same address that
the client uses to connect to the destination, or a different
encryption/auth scheme is required. There is no
scope for forcing an alternative network interface for the
native migration data with this method.
</p>
<p>
This mode cannot be invoked from virsh
</p>
<p>
Supported by QEMU driver
</p>
<h3><a id="scenariotunnelpeer2peer1">Tunnelled migration, client and peer2peer between two libvirtd servers</a></h3>
<p>
virDomainMigrate, with the VIR_MIGRATE_PEER2PEER &amp; VIR_MIGRATE_TUNNELLED
flags set, using the libvirt URI format for the 'uri' parameter. The
destination libvirtd server will automatically determine
the native hypervisor URI for migration, based off the
primary hostname. The optional uri parameter controls how
the source libvirtd connects to the destination libvirtd,
in case it is not accessible using the same address that
the client uses to connect to the destination, or a different
encryption/auth scheme is required. The native hypervisor URI
format is not used at all.

<h3><a id="nativedirectunmanaged">Native migration, client to one libvirtd server</a></h3>
<p>
virDomainMigrateToURI, without the VIR_MIGRATE_PEER2PEER flag set,
using a hypervisor specific URI format for the 'uri' parameter.
There is no use or requirement for a destination libvirtd instance
at all. This is typically used when the hypervisor has its own
native management daemon available to handle incoming migration
attempts on the destination.
</p>
<pre>
syntax: virsh migrate GUESTNAME HV-URI
eg using same libvirt URI for all connections
virsh migrate --direct web1 xenmigr://desthost/
</pre>

<h3><a id="nativepeer2peer">Native migration, peer2peer between two libvirtd servers</a></h3>
<p>
virDomainMigrateToURI, with the VIR_MIGRATE_PEER2PEER flag set,
using the libvirt URI format for the 'uri' parameter. The
destination libvirtd server will automatically determine
the native hypervisor URI for migration, based off the
primary hostname. There is no scope for forcing an alternative
network interface for the native migration data with this
method. The destination URI must be reachable using the source
libvirtd credentials (which are not necessarily the same as the
credentials of the client in connecting to the source).
</p>
<pre>
syntax: virsh migrate GUESTNAME DEST-LIBVIRT-URI [ALT-DEST-LIBVIRT-URI]
eg using same libvirt URI for all connections
virsh migrate --p2p web1 qemu+ssh://desthost/system
eg using different libvirt URI auth scheme for peer2peer connections
virsh migrate --p2p web1 qemu+ssh://desthost/system qemu+tls:/desthost/system
eg using different libvirt URI hostname for peer2peer connections
virsh migrate --p2p web1 qemu+ssh://desthost/system qemu+ssh://10.0.0.1/system
