caa4c280cd qemu: Let empty default VNC password work as documented
CVE-2016-5008

Setting an empty graphics password is documented as a way to disable
VNC/SPICE access, but QEMU does not always behaves like that. VNC would
happily accept the empty password. Let's enforce the behavior by setting
password expiration to "now".

ea02b58400 spec: Advertise nvram paths of official fedora edk2 builds
Fedora now ships edk2 firmware in its official repos, so adapt
the nvram path list to match. Eventually we can remove the nightly

Move the macro building into the %build target, which lets us

4df52fea7e spec: If installing default network, restart libvirtd
If libvirt-daemon-config-network is installed while libvirtd is already
running, the daemon doesn't notice the network. Users then have to
manually restart libvirtd (or reboot) to pick up the network.

Instead let's trigger a daemon restart when the package is first installed.
Then the default network is available immediately if libvirtd was already
running.

5c3be42813 rpc: Don't leak fd via CreateXMLWithFiles
FD passing APIs like CreateXMLWithFiles or OpenGraphicsFD will leak
file descriptors. The user passes in an fd, which is dup()'d in
virNetClientProgramCall. The new fd is what is transfered to the
server virNetClientIOWriteMessage.

Once all the fds have been written though, the parent msg->fds list
is immediately free'd, so the individual fds are never closed.

This closes each FD as its send to the server, so all fds have been
closed by the time msg->fds is free'd.

99edd11a00 libvirt.spec: remove duplicate files from -docs package
Previous commit moved some lists out of the -devel package
and into the -docs package

  commit feffcc03a0
  Author: Cole Robinson <crobinso@redhat.com>
  Date:   Wed Apr 13 10:37:42 2016 -0400

    spec: Only pull in API docs with -devel package

What was not realized is that the rule 'libvirt-docs/*'
and ' docs/*.html docs/html docs/*.gif' actually point
to the exact same content. ie, we had previously included
the website HTML in *both* the -docs and -devel packages.

So this change ended up listing the files twice, which
caused RPM to print a load of warnings:

warning: File listed twice: /usr/share/doc/libvirt-docs/html
warning: File listed twice: /usr/share/doc/libvirt-docs/html/32favicon.png

In wireshark commit ceb8d954 (v1.99.2) they have changed the

is. Now it accepts a void pointer for passing data into the

f8f58f32f6 wireshark: s/ep_alloc/wmem_alloc/
In wireshark, they have introduced their own memory allocator
wmem. This means that we need to adapt our code to that change
too. Notably 0ad15f88ccf434e8210ca is the wireshark commit you
want to look at. It's the one where they dropped the old API. The
new allocator has been introduced in 84cc3daa (v1.10.0), however,
was not exposed until 5c05c9e0 (v1.10.0). Since we already are
requiring 1.11.3 or higher no other change is needed.

f4067eef11 build: accomodate selinux 2.5 header API change
Yet again, selinux has been adding const-correctness; this change
is ABI-compatible, but breaks API, which affects us when we try to

b4a32e5103 lxc: don't try to hide parent cgroups inside container
On the host when we start a container, it will be
placed in a cgroup path of

   /machine.slice/machine-lxc\x2ddemo.scope

under /sys/fs/cgroup/*

Inside the containers' namespace we need to setup
/sys/fs/cgroup mounts, and currently will bind
mount /machine.slice/machine-lxc\x2ddemo.scope on
the host to appear as / in the container.

While this may sound nice, it confuses applications
dealing with cgroups, because /proc/$PID/cgroup
now does not match the directory in /sys/fs/cgroup

This particularly causes problems for systems and
will make it create repeated path components in
the cgroup for apps run in the container eg

  /machine.slice/machine-lxc\x2ddemo.scope/machine.slice/machine-lxc\x2ddemo.scope/user.slice/user-0.slice/session-61.scope

This also causes any systemd service that uses
sd-notify to fail to start, because when systemd
receives the notification it won't be able to
identify the corresponding unit it came from.
In particular this break rabbitmq-server startup

Future kernels will provide proper cgroup namespacing
which will handle this problem, but until that time
we should not try to play games with hiding parent
cgroups.

58e916ffaf virfile: Fix error path for forked virFileRemove
As it turns out the caller in this case expects a return < 0 for failure
and to get/use "errno" rather than using the negative of returned status.
Again different than the create path.

If someone "deleted" a file from the pool without using virsh vol-delete,
then the unlink/rmdir would return an error (-1) and set errno to ENOENT.
The caller checks errno for ENOENT when determining whether to throw an
error message indicating the failure.  Without the change, the error
message is:

error: Failed to delete vol $vol
error: cannot unlink file '/$pathto/$vol': Success

This patch thus allows the fork path to follow the non-fork path
where unlink/rmdir return -1 and errno.

d1f13a90a5 qemu: Use live autoNodeset when numatune placement is auto
https://bugzilla.redhat.com/show_bug.cgi?id=1270715

Commit id '9deb96f' removed the code to fetch the nodeset from the
CpusetMems cgroup for a running vm in favor of using the return from
virDomainNumatuneFormatNodeset introduced by commit id '43b67f2e7'.
However, that API will return the value of the passed 'auto_nodeset'
when placement is VIR_DOMAIN_NUMATUNE_PLACEMENT_AUTO, which happens
to be NULL.

Since commit id 'c74d58ad' started using priv->autoNodeset in order
to manage the auto placement value during qemuProcessStart, it should
be passed along in order to return the correct value if the domain
requests the auto placement.

76e51193e3 Close the source fd if the destination qemu exits during tunnelled migration
Tunnelled migration can hang if the destination qemu exits despite all the
ABI checks. This happens whenever the destination qemu exits before the
complete transfer is noticed by source qemu. The savevm state checks at
runtime can fail at destination and cause qemu to error out.
The source qemu cant notice it as the EPIPE is not propogated to it.
The qemuMigrationIOFunc() notices the stream being broken from virStreamSend()
and it cleans up the stream alone. The qemuMigrationWaitForCompletion() would
never get to 100% transfer completion.
The qemuMigrationWaitForCompletion() never breaks out as well since
the ssh connection to destination is healthy, and the source qemu also thinks
the migration is ongoing as the Fd to which it transfers, is never
closed or broken. So, the migration will hang forever. Even Ctrl-C on the
virsh migrate wouldn't be honoured. Close the source side FD when there is
an error in the stream. That way, the source qemu updates itself and
qemuMigrationWaitForCompletion() notices the failure.

Close the FD for all kinds of errors to be sure. The error message is not
copied for EPIPE so that the destination error is copied instead later.

Note:
Reproducible with repeated migrations between Power hosts running in different
subcores-per-core modes.

eb9aaa26a8 storage: Adjust calculation of alloc/capacity for disk
https://bugzilla.redhat.com/show_bug.cgi?id=1247987

Calculation of the extended and logical partition values for the disk
pool is complex. As the bz points out an extended partition should have
it's allocation initialized to 0 (zero) and keep the capacity as the size
dictated by the extents read.  Then for each logical partition found,
adjust the allocation of the extended partition.

Finally, previous logic tried to avoid recalculating things if a logical
partition was deleted; however, since we now have special logic to handle
the allocation of the extended partition, just make life easier by reading
the partition table again - rather than doing the reverse adjustment.

770ffbf857 qemu: Add conditions for qemu-kvm use on ppc64
qemu-kvm can be used to run ppc64 guests on ppc64le hosts and vice
versa, since the hardware is actually the same and the endianness
is chosen by the guest kernel.

Up until now, however, libvirt didn't allow the use of qemu-kvm
to run guests if their endianness didn't match the host's.

f3ac5d6a6c rpc: libssh2: Fix regression in ssh host key verification
Commit 792f81a40e caused a regression in the libssh2 host key
verification code by changing the variable type of 'i' to unsigned.
Since one of the loops used -1 as a special value if the asking
callback was found the conversion made a subsequent test always fail.

The bug was stealth enough to pass review, compilers and coverity.

9a51c50048 Update pool allocation with new values on volume creation
Since commit e0139e3, we update the pool allocation with
the user-provided allocation values.

For qcow2, the allocation is ignored for volume building,
but we still subtracted it from pool's allocation.
This can result in interesting values if the user-provided
allocation is large enough:

Capacity:       104.71 GiB
Allocation:     109.13 GiB
Available:      16.00 EiB

We already do a VolRefresh on volume creation. Also refresh
the volume after creating and use the new value to update the pool.

64be645161 virDomainCreateXML: Make domain definition transient
https://bugzilla.redhat.com/show_bug.cgi?id=871452

So, you want to create a domain from XML. The domain already
exists in libvirt's database of domains. It's okay, because name
and UUID matches. However, on domain startup, internal
representation of the domain is overwritten with your XML even
though we claim that the XML you've provided is a transient one.
The bug is to be found across nearly all the drivers.

e89b42ccc6 virDomainCreateXML: Don't remove persistent domains on error
https://bugzilla.redhat.com/show_bug.cgi?id=871452

Okay, so we allow users to 'virsh create' an already existing
domain, providing completely different XML than the one stored in
Libvirt. Well, as long as name and UUID matches. However, in some
drivers the code that handles errors unconditionally removes the
domain that failed to start even though the domain might have
been persistent. Fortunately, the domain is removed just from the
internal list of domains and the config file is kept around.

Steps to reproduce:

1) virsh dumpxml $dom > /tmp/dom.xml
2) change XML so that it is still parse-able but won't boot, e.g.
change guest agent path to /foo/bar
3) virsh create /tmp/dom.xml
4) virsh dumpxml $dom
5) Observe "No such domain" error

0099781e80 domain: Fix migratable XML with graphics/@listen
As of commit 6992994, we set graphics/@listen attribute according to the
first listen child element even if that element is of type='network'.
This was done for backward compatibility with applications which only
support the original listen attribute. However, by doing so we broke
migration to older libvirt which tried to check that the listen
attribute matches one of the listen child elements but which did not
take type='network' elements into account.

We are not concerned about compatibility with old applications when
formatting domain XML for migration for two reasons. The XML is consumed
only by libvirtd and the IP address associated with type='network'
listen address on the source host is just useless on the destination
host. Thus, we can safely avoid propagating the type='network' IP
address to graphics/@listen attribute when creating migratable XML.

d035796675 CVE-2015-5313: storage: don't allow '/' in filesystem volume names
The libvirt file system storage driver determines what file to
act on by concatenating the pool location with the volume name.
If a user is able to pick names like "../../../etc/passwd", then
they can escape the bounds of the pool.  For that matter,
virStoragePoolListVolumes() doesn't descend into subdirectories,
so a user really shouldn't use a name with a slash.

Normally, only privileged users can coerce libvirt into creating
or opening existing files using the virStorageVol APIs; and such
users already have full privilege to create any domain XML (so it
is not an escalation of privilege).  But in the case of
fine-grained ACLs, it is feasible that a user can be granted
storage_vol:create but not domain:write, and it violates
assumptions if such a user can abuse libvirt to access files
outside of the storage pool.

Therefore, prevent all use of volume names that contain "/",
whether or not such a name is actually attempting to escape the
pool.

This changes things from:

$ virsh vol-create-as default ../../../../../../etc/haha --capacity 128
Vol ../../../../../../etc/haha created
$ rm /etc/haha

to:

$ virsh vol-create-as default ../../../../../../etc/haha --capacity 128
error: Failed to create vol ../../../../../../etc/haha
error: Requested operation is not valid: volume name '../../../../../../etc/haha' cannot contain '/'

9372343f7c xen: fix race in refresh of config cache
The xenXMConfigCacheRefresh method scans /etc/xen and loads
all config files it finds. It then scans its internal hash
table and purges any (previously) loaded config files whose
refresh timestamp does not match the timestamp recorded at
the start of xenXMConfigCacheRefresh(). There is unfortunately
a subtle flaw in this, because if loading the config files
takes longer than 1 second, some of the config files will
have a refresh timestamp that is 1 or more seconds different
(newer) than is checked for. So we immediately purge a bunch
of valid config files we just loaded.

To avoid this flaw, we must pass the timestamp we record at
the start of xenXMConfigCacheRefresh() into the
xenXMConfigCacheAddFile() method, instead of letting the
latter call time(NULL) again.

b64d62c6b8 util: fallback to ioctl(SIOCBRDELBR) if netlink RTM_DELLINK fails
commit 09778e09 switched from using ioctl(SIOCBRDELBR) for bridge
device deletion to using a netlink RTM_DELLINK message, which is the
more modern way to delete a bridge (and also doesn't require the
bridge to be ~IFF_UP to succeed). However, although older kernels
(e.g. 2.6.32, in RHEL6/CentOS6) support deleting *some* link types
with RTM_NEWLINK, they don't support deleting bridges, and there is no
compile-time way to figure this out.

This patch moves the body of the SIOCBRDELBR version of
virNetDevBridgeDelete() into a static function, calls the new function
from the original, and also calls the new function from the
RTM_DELLINK version if the RTM_DELLINK message generates an EOPNOTSUPP
error. Since RTM_DELLINK is done from the subordinate function
virNetlinkDelLink, which is also called for other purposes (deleting a
macvtap interface), a function pointer called "fallback" has been
added to the arglist of virNetlinkDelLink() - if that arg != NULL, the
provided function will be called when (and only when) RTM_DELLINK
fails with EOPNOTSUPP.

e6c69718e2 util: fallback to ioctl(SIOCBRADDBR) if netlink RTM_NEWLINK fails
commit fc7b23db switched from using ioctl(SIOCBRADDBR) for bridge
creation to using a netlink RTM_NEWLINK message with IFLA_INFO_KIND =
"bridge", which is the more modern way to create a bridge. However,
although older kernels (e.g. 2.6.32, in RHEL6/CentOS6) support
creating *some* link types with RTM_NEWLINK, they don't support
creating bridges, and there is no compile-time way to figure this out
(since the "type" isn't an enum, but rather a character string).

This patch moves the body of the SIOCBRADDBR version of
virNetDevBridgeCreate() into a static function, calls the new function
from the original, and also calls the new function from the
RTM_NEWLINK version if the RTM_NEWLINK message generates an EOPNOTSUPP
error.

24d194ad59 libxl: fix ref counting of libxlMigrationDstArgs
This patch fixes some flawed logic around ref counting the
libxlMigrationDstArgs object.

First, when adding sockets to the event loop with
virNetSocketAddIOCallback(), the generic virObjectFreeCallback()
was registered as a free function, with libxlMigrationDstArgs as
its parameter. A reference was also taken on
libxlMigrationDstArgs for each successful call to
virNetSocketAddIOCallback(). The rational behind this logic was
that the libxlMigrationDstArgs object had to out-live the socket
objects. But virNetSocketAddIOCallback() already takes a
reference on socket objects, ensuring their life until removed
from the event loop and unref'ed in virNetSocketEventFree(). We
only need to ensure libxlMigrationDstArgs lives until
libxlDoMigrateReceive() finishes, which can be done by simply
unref'ing libxlMigrationDstArgs at the end of
libxlDoMigrateReceive().

The second flaw was unref'ing the sockets in the failure path of
libxlMigrateReceive() and at the end of libxlDoMigrateReceive().
As mentioned above, the sockets are already unref'ed by
virNetSocketEventFree() when removed from the event loop.
Attempting to unref the socket a second time resulted in a
libvirtd crash since the socket was previously unref'ed and
disposed.

So I've taken look at valid_path() because it is obviously
calling array_starts_with() with malformed @size. And here's the
result: there are two variables to hold the size of three arrays
and their value is recalculated before each call of
array_starts_with(). What if we just use three variables,
initialize them and do not touch them afterwards?

affa75e640 qemu: Emit correct audit message for memory hot unplug
https://bugzilla.redhat.com/show_bug.cgi?id=1226234#c3

If the qemu monitor fails to remove the memory from the guest for
any reason, the auditlog message will incorrectly use the current
actual memory (via virDomainDefGetMemoryActual) instead of the
value we were attempting to reduce to. The result is the 'new-mem'
and 'old-mem' values for the auditlog message would be identical.

This patch creates a local 'newmem' which accounts for the current
memory size minus the memory which is being removed. NB, for the
success case this results in the same value that would be returned
by virDomainDefGetMemoryActual without the need to do the math. This
follows the existing code which would subtract the size for cur_balloon.

fec2c786e7 qemu: Emit correct audit message for memory hot plug
https://bugzilla.redhat.com/show_bug.cgi?id=1226234#c3

Prior to this patch, after successfully hot plugging memory
the audit log indicated that the update failed, e.g.:

type=VIRT_RESOURCE ... old-mem=1024000 new-mem=1548288 \
exe="/usr/sbin/libvirtd" hostname=? addr=? terminal=pts/2 res=failed

This patch will adjust where virDomainAuditMemory is called to
ensure the proper 'ret' value is used based on success or failure.

Additionally, the audit message should include the size of the
memory we were attempting to change to rather than the current
actual size. On failure to add, the message showed the same value
for old-mem and new-mem.

In order to do this, introduce a 'newmem' local which will compute
the new size based on the oldmem size plus the size of memory we
are about to add. NB: This would be the same as calling the
virDomainDefGetMemoryActual again on success, but avoids the
overhead of recalculating. Plus cur_balloon is already adjusted
by the same value, so this follows that.

Since iothread_id == 0 is an invalid value for QEMU let's point

It seems during many reviews/edits to the code the check for
iothread_id = 0 being invalid was lost - it could have originally

4a3bd30e50 virsh: Reset global error after successfull domain lookup
When looking up a domain, we try to look up by ID, UUID and NAME
consequently while not really caring which of those lookups succeeds.
The problem is that if any of them fails, we dispatch the error from the
driver and that means setting both threadlocal and global error. Let's
say the last lookup (by NAME) succeeds and resets the threadlocal error as any
other API does, however leaving the global error unchanged. If the underlying
virsh command does not succeed afterwards, our cleanup routine in
vshCommandRun ensures that no libvirt error will be forgotten and that's
exactly where this global error comes in incorrectly.

 # virsh domif-setlink 123 vnet1 up
 error: interface (target: vnet1) not found
 error: Domain not found: no domain with matching id 123

This patch also resets the global error which would otherwise cause some
minor confusion in reported error messages.

edf314d710 qemu: Fix segfault when parsing private domain data
When parsing private domain data, there are two paths that are flawed.
They are both error paths, just from different parts of the function.
One of them can call free() on an uninitialized pointer.  Initialization
to NULL is enough here.  The other one is a bit trickier to explain, but
as easy as the first one to fix.  We create capabilities, parse them and
then assign them into the private data pointer inside the domain object.
If, however, we get to fail from now on, the error path calls unrefs the
capabilities and then, when the domain object is being cleaned,
qemuDomainObjPrivateFree() tries to unref them as well.  That causes a
segfault.  Settin the pointer to NULL upon successful addition to the
private data is enough.

58211ca54d util: don't overwrite stack when getting ethtool gfeatures
This fixes the crash described here:

 https://www.redhat.com/archives/libvir-list/2015-August/msg00162.html

In short, we were calling ioctl(SIOCETHTOOL) pointing to a too-short
object that was a local on the stack, resulting in the memory past the
end of the object being overwritten. This was because the struct used
by the ETHTOOL_GFEATURES command of SIOCETHTOOL ends with a 0-length
array, but we were telling ethtool that it could use 2 elements on the
array.

The fix is to allocate the necessary memory with VIR_ALLOC_VAR(),
including the extra length needed for a 2 element array at the end.

range of a virtual network.

Extra test cases are also added to verify that virSocketAddrGetRange()
works properly in both positive and negative cases when the network
pointer is NULL.

This is the *real* fix for:

https://bugzilla.redhat.com/show_bug.cgi?id=985653

Commits 1e334a and 48e8b9 had earlier been pushed as fixes for that
bug, but I had neglected to read the report carefully, so instead of
fixing validation for the NAT range, I had fixed validation for the
DHCP range. sigh.

96a808f476 virNetDevBandwidthParseRate: Reject negative values
https://bugzilla.redhat.com/show_bug.cgi?id=1022292

The following XML really does not make any sense:

<inbound average="-1" burst="-2" peak="-3" floor="-4"/>

There can't be a negative packet rate. Well, so far we haven't
assigned any meaning to it. So reject it unless users harm themselves,
because otherwise we turn the negative numbers into really big values.

06cea21924 network: verify proper address family in updates to <host> and <range>
By specifying parentIndex in a call to virNetworkUpdate(), it was
possible to direct libvirt to add a dhcp range or static host of a
non-matching address family to the <dhcp> element of an <ip>. For
example, given:

 <ip address='192.168.122.1' netmask='255.255.255.0'/>
 <ip family='ipv6' address='2001:db6:ca3:45::1' prefix='64'/>

you could provide a static host entry with an IPv4 address, and
specify that it be added to the 2nd <ip> element (index 1):

  virsh net-update default add ip-dhcp-host --parent-index 1 \
  '<host mac="52:54:00:00:00:01" ip="192.168.122.45"/>'

This would be happily added with no error (and no concern of any
possible future consequences).

This patch checks that any dhcp range or host element being added to a
network ip's <dhcp> subelement has addresses of the same family as the
ip element they are being added to.

This resolves:

b2e6de689f conf: more useful error message when pci function is out of range
If a pci address had a function number out of range, the error message
would be:

  Insufficient specification for PCI address

which is logged by virDevicePCIAddressParseXML() after
virDevicePCIAddressIsValid returns a failure.

This patch enhances virDevicePCIAddressIsValid() to optionally report
the error itself (since it is the place that decides which part of the
address is "invalid"), and uses that feature when calling from
virDevicePCIAddressParseXML(), so that the error will be more useful,
e.g.:

  Invalid PCI address function=0x8, must be <= 7

Previously, virDevicePCIAddressIsValid didn't check for the
theoretical limits of domain or bus, only for slot or function. While
adding log messages, we also correct that ommission. (The RNG for PCI
addresses already enforces this limit, which by the way means that we
can't add any negative tests for this - as far as I know our
domainschematest has no provisions for passing XML that is supposed to
fail).

Note that virDevicePCIAddressIsValid() can only check against the
absolute maximum attribute values for *any* possible PCI controller,
not for the actual maximums of the specific controller that this
device is attaching to; fortunately there is later more specific
validation for guest-side PCI addresses when building the set of
assigned PCI addresses. For host-side PCI addresses (e.g. for
<hostdev> and for network device pools), we rely on the error that
will be logged when it is found that the device doesn't actually
exist.

This resolves:

9e41bdf4d0 qemu: Forbid image pre-creation for non-shared storage migration
Libvirt doesn't reliably know the location of the backing chain when
pre-creating images for non-shared migration. This isn't a problem for
full copy, but incremental copy requires the information.

Forbid pre-creating the image in cases where incremental migration is
required. This limitation can perhaps be lifted once libvirt will fully
support loading of backing chain information from the XML.

93fd967f38 storage: only run safezero if allocation is > 0
While a zero allocation in safezero should be fine it isn't when we use
posix_fallocate which returns EINVAL on a zero allocation.

While we could skip the zero allocation in safezero_posix_fallocate it's
an optimization to do it for all allocations.

This fixes vm installation via virtinst for me which otherwise aborts
like:

Qemu reports physical size 0 for block devices. As 15fa84acbb

This patch adds code to refresh the physical size of a block device by
opening it and seeking to the end and uses it both in
qemuDomainGetBlockInfo and also in qemuDomainGetStatsOneBlock that was

The problem is, when registering remoteClientCloseFunc(), it's
conn->closeCallback which is ref'd. But in the function itself
it's conn->closeCallback->conn what is unref'd. This is causing
imbalance in reference counting. Moreover, there's no need for
the remote driver to increase/decrease conn refcount since it's
not used anywhere. It's just merely passed to client registered
callback. And for that purpose it's correctly ref'd in
virConnectRegisterCloseCallback() and then unref'd in
virConnectUnregisterCloseCallback().

e63b32e22d storage: Correct the 'mode' check
Commit id '7c2d65dde2' changed the default value of mode to be -1 if not
supplied in the XML, which should cause creation of the volume using the
default mode of VIR_STORAGE_DEFAULT_VOL_PERM_MODE; however, the check
made was whether mode was '0' or not to use default or provided value.

This patch fixes the issue to check if the 'mode' was provided in the XML
and use that value.

075eb526c9 storage: Handle failure from refreshVol
Commit id '155ca616' added the 'refreshVol' API. In an NFS root-squash
environment it was possible that if the just created volume from XML wasn't
properly created with the right uid/gid and/or mode, then the followup
refreshVol will fail to open the volume in order to get the allocation/
capacity values. This would leave the volume still on the server and
cause a libvirtd crash because 'voldef' would be in the pool list, but
the cleanup code would free it.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.

[![Build Status](https://travis-ci.org/libvirt/libvirt.svg)](https://travis-ci.org/libvirt/libvirt)
[![CII Best Practices](https://bestpractices.coreinfrastructure.org/projects/355/badge)](https://bestpractices.coreinfrastructure.org/projects/355)
Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
Further information about the libvirt project can be found on the
website:
[https://libvirt.org](https://libvirt.org)
License
-------
The libvirt C API is distributed under the terms of GNU Lesser General
Public License, version 2.1 (or later). Some parts of the code that are
not part of the C library may have the more restrictive GNU General
Public License, version 2.1 (or later). See the files `COPYING.LESSER`
and `COPYING` for full license terms & conditions.
Installation
------------
Libvirt uses the GNU Autotools build system, so in general can be built
and installed with the usual commands. For example, to build in a manner
that is suitable for installing as root, use:
```
$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install
```
While to build & install as an unprivileged user
```
$ ./configure --prefix=$HOME/usr
$ make
$ make install
```
The libvirt code relies on a large number of 3rd party libraries. These will
be detected during execution of the `configure` script and a summary printed
which lists any missing (optional) dependencies.
Contributing
------------
The libvirt project welcomes contributions in many ways. For most components
the best way to contribute is to send patches to the primary development
mailing list. Further guidance on this can be found on the website:
[https://libvirt.org/contribute.html](https://libvirt.org/contribute.html)
Contact
-------
The libvirt project has two primary mailing lists:
* libvirt-users@redhat.com (**for user discussions**)
* libvir-list@redhat.com (**for development only**)
Further details on contacting the project are available on the website:

For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
are honored.
Gnulib sources can be fetched in various ways:
* If this package is in a git repository with a 'gnulib' submodule
configured, then that submodule is initialized and updated and sources
are fetched from there. If \$GNULIB_SRCDIR is set (directly or via
--gnulib-srcdir) and is a git repository, then it is used as a reference.
* Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir),
then sources are fetched from that local directory. If it is a git
repository and \$GNULIB_REVISION is set, then that revision is checked
out.
* Otherwise, if this package is in a git repository with a 'gnulib'
submodule configured, then that submodule is initialized and updated and
sources are fetched from there.
* Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are
cloned into that directory using git from \$GNULIB_URL, defaulting to
$default_gnulib_url.
If \$GNULIB_REVISION is set, then that revision is checked out.
* Otherwise, the existing Gnulib sources in the 'gnulib' directory are
used. If it is a git repository and \$GNULIB_REVISION is set, then that
revision is checked out.
If you maintain a package and want to pin a particular revision of the
Gnulib sources that has been tested with your package, then there are two
possible approaches: either configure a 'gnulib' submodule with the
appropriate revision, or set \$GNULIB_REVISION (and if necessary
\$GNULIB_URL) in $me.conf.
Running without arguments will suffice in most cases.

Threading in the libvirtd daemon
================================
To allow efficient processing of RPC requests, the libvirtd daemon
makes use of threads.
- The process leader. This is the initial thread of control
when the daemon starts running. It is responsible for
initializing all the state, and starting the event loop.
Once that's all done, this thread does nothing except
wait for the event loop to quit, thus indicating an orderly
shutdown is required.
- The event loop. This thread runs the event loop, sitting
in poll() on all monitored file handles, and calculating
and dispatching any timers that may be registered. When
this thread quits, the entire daemon will shutdown.
- The workers. These 'n' threads all sit around waiting to
process incoming RPC requests. Since RPC requests may take
a long time to complete, with long idle periods, there will
be quite a few workers running.
The use of threads obviously requires locking to ensure safety when
accessing/changing data structures.
- the top level lock is on 'struct qemud_server'. This must be
held before acquiring any other lock
- Each 'struct qemud_client' object has a lock. The server lock
must be held before acquiring it. Once the client lock is acquired
the server lock can (optionally) be dropped.
- The event loop has its own self-contained lock. You can ignore
this as a caller of virEvent APIs.
The server lock is used in conjunction with a condition variable
to pass jobs from the event loop thread to the workers. The main
event loop thread handles I/O from the client socket, and once a
complete RPC message has been read off the wire (and optionally
decrypted), it will be placed on the 'dx' job queue for the
associated client object. The job condition will be signalled and
a worker will wakup and process it.
The worker thread must quickly drop its locks on the server and
client to allow the main event loop thread to continue running
with its other work. Critically important, is that now libvirt
API call will ever be made with the server or client locks held.

# restrictions on connecting to the socket (eg, UNIX
# socket permissions), or if there is a lower layer in
# the network providing auth (eg, TLS/x509 certificates)

# controlled from /etc/sasl2/libvirt.conf. For the TCP
# socket only GSSAPI & DIGEST-MD5 mechanisms will be used.
# For non-TCP or TLS sockets, any scheme is allowed.
#
# - polkit: use PolicyKit to authenticate. This is only suitable
# for use on the UNIX sockets. The default policy will
# require a user to supply their own password to gain
# full read/write access (aka sudo like), while anyone
# is allowed read/only access.

# Change the authentication scheme for TCP sockets.
#
# If you don't enable SASL, then all TCP traffic is cleartext.

# Logging controls
#
# Logging level: 4 errors, 3 warnings, 2 information, 1 debug
# basically 1 will log everything possible
# Note: Journald may employ rate limiting of the messages logged
# and thus lock up the libvirt daemon. To use the debug level with
# journald you have to specify it explicitly in 'log_outputs', otherwise
# only information level messages will be logged.
#log_level = 3
# Logging filters:
# A filter allows to select a different logging level for a given category
# of logs
# The format for a filter is one of:
# x:name
# x:+name
# where name is a string which is matched against source file name,
# e.g., "remote", "qemu", or "util/json", the optional "+" prefix
# tells libvirt to log stack trace for each message matching name,
# and x is the minimal level where matching messages should be logged:
# 1: DEBUG
# 2: INFO
# 3: WARNING
# 4: ERROR
#
# Multiple filters can be defined in a single @filters, they just need to be
# separated by spaces.
#
# e.g. to only get warning or errors from the remote layer and only errors
# from the event layer:
#log_filters="3:remote 4:event"
# Logging outputs:
# An output is one of the places to save logging information
# The format for an output can be:
# x:stderr
# output goes to stderr
# x:syslog:name
# use syslog for the output and use the given name as the ident
# x:file:file_path
# output to a file, with the given filepath
# x:journald
# output to journald logging system
# In all case the x prefix is the minimal level, acting as a filter
# 1: DEBUG
# 2: INFO
# 3: WARNING
# 4: ERROR
#
# Multiple outputs can be defined, they just need to be separated by spaces.
# e.g. to log all warnings and errors to syslog under the libvirtd ident:
#log_outputs="3:syslog:libvirtd"
#
# Log debug buffer size:
#
# This configuration option is no longer used, since the global
# log buffer functionality has been removed. Please configure
# suitable log_outputs/log_filters settings to obtain logs.
#log_buffer_size = 64
##################################################################
#
# Auditing
#
# This setting allows usage of the auditing subsystem to be altered:
#
# audit_level == 0 -> disable all auditing
# audit_level == 1 -> enable auditing, only if enabled on host (default)
# audit_level == 2 -> enable auditing, and exit if disabled on host
#
#audit_level = 2
#
# If set to 1, then audit messages will also be sent
# via libvirt logging infrastructure. Defaults to 0
#
#audit_logging = 1
###################################################################
# UUID of the host:
# Provide the UUID of the host here in case the command
# 'dmidecode -s system-uuid' does not provide a valid uuid. In case
# 'dmidecode' does not provide a valid UUID and none is provided here, a
# temporary UUID will be generated.
# Keep the format of the example UUID below. UUID must not have all digits
# be the same.
# NB This default all-zeros UUID will not work. Replace
# it with the output of the 'uuidgen' command and then
# uncomment this entry
#host_uuid = "00000000-0000-0000-0000-000000000000"
###################################################################
# Keepalive protocol:
# This allows libvirtd to detect broken client connections or even
# dead clients. 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 daemon 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.
#
#keepalive_required = 1
# Keepalive settings for the admin interface
#admin_keepalive_interval = 5
#admin_keepalive_count = 5
#
#admin_keepalive_required = 1

=head1 NAME
libvirtd - libvirtd management daemon
=head1 SYNOPSIS
B<libvirtd> [ -dlv ] [ -f config_file ] [ -p pid_file ] [ -t timeout_seconds ]
B<libvirtd> --version
=head1 DESCRIPTION
The B<libvirtd> program is the server side daemon component of the libvirt
virtualization management system.
This daemon runs on host servers and performs required management tasks for
virtualized guests. This includes activities such as starting, stopping
and migrating guests between host servers, configuring and manipulating
networking, and managing storage for use by guests.
The libvirt client libraries and utilities connect to this daemon to issue
tasks and collect information about the configuration and resources of the host
system and guests.
By default, the libvirtd daemon listens for requests on a local Unix domain
socket. Using the B<-l>|B<--listen> command line option, the libvirtd daemon
can be instructed to additionally listen on a TCP/IP socket. The TCP/IP socket
to use is defined in the libvirtd configuration file.
Restarting libvirtd does not impact running guests. Guests continue to operate
and will be picked up automatically if their XML configuration has been
defined. Any guests whose XML configuration has not been defined will be lost
from the configuration.
=head1 OPTIONS
=over
=item B<-h, --help>
Display command line help usage then exit.
=item B<-d, --daemon>

=item B<-p, --pid-file> I<FILE>
Use this name for the PID file, overriding the default value.
=item B<-t, --timeout> I<SECONDS>
Exit after timeout period (in seconds) elapse with no client connections
or registered resources. Be aware that resources such as autostart
networks will result in never reaching the timeout, even when there are
no client connections.
=item B<-v, --verbose>
Enable output of verbose messages.

The <code>connect_driver</code> parameter describes the
client's <a href="remote.html">remote Connection Driver</a>
name based on the <a href="uri.html">URI</a> used for the
connection.
</p>
<p>
<span class="since">Since 4.1.0</span>, when calling an API
outside the scope of the primary connection driver, the
primary driver will attempt to open a secondary connection
to the specific API driver in order to process the API. For
example, when hypervisor domain processing needs to make an
API call within the storage driver or the network filter driver
an attempt to open a connection to the "storage" or "nwfilter"
driver will be made. Similarly, a "storage" primary connection
may need to create a connection to the "secret" driver in order
to process secrets for the API. If successful, then calls to
those API's will occur in the <code>connect_driver</code> context
of the secondary connection driver rather than in the context of
the primary driver. This affects the <code>connect_driver</code>
returned from rule generation from the <code>action.loookup</code>
function. The following table provides a list of the various
connection drivers and the <code>connect_driver</code> name
used by each regardless of primary or secondary connection.
The access denied error message from libvirt will list the
connection driver by name that denied the access.

It is always a good idea to patch the test driver in addition to the
target driver, to prove that the API can be used for more than one
driver.
In the example patches, three separate drivers are supported:
test, qemu, and xen. It is always a good idea to patch the test
driver in addition to the target driver, to prove that the API
can be used for more than one driver. The example updates the
test driver in one patch:
</p>
<p class="example">See <a href="api_extension/0009-support-all-flags-in-test-driver.patch">0009-support-all-flags-in-test-driver.patch</a></p>
<p>
Any cleanups resulting from the changes should be added as separate
patches at the end of the series.
The qemu changes were easier to split into two phases, one for
updating the mapping between the new XML and the hypervisor
command line arguments, and one for supporting all possible
flags of the new API:
</p>
<p class="example">See <a href="api_extension/0010-improve-vcpu-support-in-qemu-command-line.patch">0010-improve-vcpu-support-in-qemu-command-line.patch</a>
and <a href="api_extension/0011-complete-vcpu-support-in-qemu-driver.patch">0011-complete-vcpu-support-in-qemu-driver.patch</a></p>
<p>
Finally, the example breaks the xen driver changes across four
patches. One maps the XML changes to the hypervisor command,
the next two are independently implementing the getter and
setter APIs, and the last one provides cleanup of code that was
rendered dead by the new API.
</p>
<p class="example">See <a href="api_extension/0012-improve-vcpu-support-in-xen-command-line.patch">0012-improve-vcpu-support-in-xen-command-line.patch</a>,
<a href="api_extension/0013-improve-getting-xen-vcpu-counts.patch">0013-improve-getting-xen-vcpu-counts.patch</a>,

and <a href="api_extension/0015-remove-dead-xen-code.patch">0015-remove-dead-xen-code.patch</a></p>

The exact details of the example code are probably uninteresting
unless you're concerned with virtual cpu management.

Subject: [PATCH 04/15] vcpu: implement the public APIs
Factors common checks (such as nonzero vcpu count) up front, but
drivers will still need to do additional flag checks.
* src/libvirt.c (virDomainSetVcpusFlags, virDomainGetVcpusFlags):
New functions.
(virDomainSetVcpus, virDomainGetMaxVcpus): Refer to new API.

Done by editing the first three files, then running
'make -C src rpcgen', then editing src/remote_protocol-structs
to match.
* daemon/remote.c (remoteDispatchDomainSetVcpusFlags)
(remoteDispatchDomainGetVcpusFlags): New functions.
* src/remote/remote_driver.c (remoteDomainSetVcpusFlags)
(remoteDomainGetVcpusFlags, remote_driver): Client side
serialization.
* src/remote/remote_protocol.x
(remote_domain_set_vcpus_flags_args)
(remote_domain_get_vcpus_flags_args)
(remote_domain_get_vcpus_flags_ret)
(REMOTE_PROC_DOMAIN_SET_VCPUS_FLAGS)
(REMOTE_PROC_DOMAIN_GET_VCPUS_FLAGS): Define wire format.
* daemon/remote_dispatch_args.h: Regenerate.
* daemon/remote_dispatch_prototypes.h: Likewise.
* daemon/remote_dispatch_table.h: Likewise.

From 50c51f13e2af04afac46e181c4ed62581545a488 Mon Sep 17 00:00:00 2001
From: Eric Blake <eblake@redhat.com>
Date: Mon, 27 Sep 2010 16:37:53 -0600
Subject: [PATCH 06/15] vcpu: make old API trivially wrap to new API
Note - this wrapping is completely mechanical; the old API will
function identically, since the new API validates that the exact
same flags are provided by the old API. On a per-driver basis,
it may make sense to have the old API pass a different set of flags,
but that should be done in the per-driver patch that implements
the full range of flag support in the new API.
* src/esx/esx_driver.c (esxDomainSetVcpus, escDomainGetMaxVpcus):
Move guts...
(esxDomainSetVcpusFlags, esxDomainGetVcpusFlags): ...to new
functions.
(esxDriver): Trivially support the new API.
* src/openvz/openvz_driver.c (openvzDomainSetVcpus)
(openvzDomainSetVcpusFlags, openvzDomainGetMaxVcpus)
(openvzDomainGetVcpusFlags, openvzDriver): Likewise.
* src/phyp/phyp_driver.c (phypDomainSetCPU)
(phypDomainSetVcpusFlags, phypGetLparCPUMAX)
(phypDomainGetVcpusFlags, phypDriver): Likewise.
* src/qemu/qemu_driver.c (qemudDomainSetVcpus)
(qemudDomainSetVcpusFlags, qemudDomainGetMaxVcpus)
(qemudDomainGetVcpusFlags, qemuDriver): Likewise.
* src/test/test_driver.c (testSetVcpus, testDomainSetVcpusFlags)
(testDomainGetMaxVcpus, testDomainGetVcpusFlags, testDriver):
Likewise.
* src/vbox/vbox_tmpl.c (vboxDomainSetVcpus)
(vboxDomainSetVcpusFlags, virDomainGetMaxVcpus)
(virDomainGetVcpusFlags, virDriver): Likewise.
* src/xen/xen_driver.c (xenUnifiedDomainSetVcpus)
(xenUnifiedDomainSetVcpusFlags, xenUnifiedDomainGetMaxVcpus)
(xenUnifiedDomainGetVcpusFlags, xenUnifiedDriver): Likewise.
* src/xenapi/xenapi_driver.c (xenapiDomainSetVcpus)
(xenapiDomainSetVcpusFlags, xenapiDomainGetMaxVcpus)
(xenapiDomainGetVcpusFlags, xenapiDriver): Likewise.
(xenapiError): New helper macro.

From bf945ee97b72d3b0c4fc2da04530f5294f529d66 Mon Sep 17 00:00:00 2001
From: Eric Blake <eblake@redhat.com>
Date: Wed, 29 Sep 2010 15:20:23 -0600
Subject: [PATCH 08/15] vcpu: add virsh support
* tools/virsh.c (cmdSetvcpus): Add new flags. Let invalid
commands through to driver, to ease testing of hypervisor argument
validation.
(cmdMaxvcpus, cmdVcpucount): New commands.
(commands): Add new commands.
* tools/virsh.pod (setvcpus, vcpucount, maxvcpus): Document new
behavior.

Subject: [PATCH 07/15] vcpu: support maxvcpu in domain_conf
Although this patch adds a distinction between maximum vcpus and
current vcpus in the XML, the values should be identical for all
drivers at this point. Only in subsequent per-driver patches will
a distinction be made.
In general, virDomainGetInfo should prefer the current vcpus.
* src/conf/domain_conf.h (_virDomainDef): Adjust vcpus to unsigned
short, to match virDomainGetInfo limit. Add maxvcpus member.
* src/conf/domain_conf.c (virDomainDefParseXML)
(virDomainDefFormat): parse and print out vcpu details.
* src/xen/xend_internal.c (xenDaemonParseSxpr)
(xenDaemonFormatSxpr): Manage both vcpu numbers, and require them
to be equal for now.
* src/xen/xm_internal.c (xenXMDomainConfigParse)
(xenXMDomainConfigFormat): Likewise.
* src/phyp/phyp_driver.c (phypDomainDumpXML): Likewise.
* src/openvz/openvz_conf.c (openvzLoadDomains): Likewise.
* src/openvz/openvz_driver.c (openvzDomainDefineXML)
(openvzDomainCreateXML, openvzDomainSetVcpusInternal): Likewise.
* src/vbox/vbox_tmpl.c (vboxDomainDumpXML, vboxDomainDefineXML):
Likewise.
* src/xenapi/xenapi_driver.c (xenapiDomainDumpXML): Likewise.
* src/xenapi/xenapi_utils.c (createVMRecordFromXml): Likewise.
* src/esx/esx_vmx.c (esxVMX_ParseConfig, esxVMX_FormatConfig):
Likewise.
* src/qemu/qemu_conf.c (qemuBuildSmpArgStr)
(qemuParseCommandLineSmp, qemuParseCommandLine): Likewise.
* src/qemu/qemu_driver.c (qemudDomainHotplugVcpus): Likewise.
* src/opennebula/one_conf.c (xmlOneTemplate): Likewise.

Subject: [PATCH 12/15] vcpu: improve vcpu support in xen command line
This patch series focuses on xendConfigVersion 2 (xm_internal) and 3
(xend_internal), but leaves out changes for xenapi drivers.
See this link for more details about vcpu_avail for xm usage.
http://lists.xensource.com/archives/html/xen-devel/2009-11/msg01061.html
This relies on the fact that def->maxvcpus can be at most 32 with xen.
* src/xen/xend_internal.c (xenDaemonParseSxpr)
(sexpr_to_xend_domain_info, xenDaemonFormatSxpr): Use vcpu_avail
when current vcpus is less than maximum.
* src/xen/xm_internal.c (xenXMDomainConfigParse)
(xenXMDomainConfigFormat): Likewise.
* tests/xml2sexprdata/xml2sexpr-pv-vcpus.sexpr: New file.
* tests/sexpr2xmldata/sexpr2xml-pv-vcpus.sexpr: Likewise.
* tests/sexpr2xmldata/sexpr2xml-pv-vcpus.xml: Likewise.
* tests/xmconfigdata/test-paravirt-vcpu.cfg: Likewise.
* tests/xmconfigdata/test-paravirt-vcpu.xml: Likewise.
* tests/xml2sexprtest.c (mymain): New test.
* tests/sexpr2xmltest.c (mymain): Likewise.
* tests/xmconfigtest.c (mymain): Likewise.

Subject: [PATCH 14/15] vcpu: improve support for setting xen vcpu counts
Tested with RHEL 5.6 (xendConfigVersion 2, where xend_internal
controls live domains and xm_internal controls inactive domains).
Hopefully this works with xendConfigVersion 3 (where xend_internal
controls everything).
* src/xen/xen_driver.c (xenUnifiedDomainSetVcpusFlags): Support
more flags.
(xenUnifiedGetMaxVcpus): Export.
* src/xen/xm_internal.h (xenXMDomainSetVcpusFlags): New prototype.
* src/xen/xend_internal.h (xenDaemonDomainSetVcpusFlags): Likewise.
* src/xen/xen_driver.h (xenUnifiedGetMaxVcpus): Likewise.
* src/xen/xm_internal.c (xenXMDomainSetVcpusFlags): New function.
* src/xen/xend_internal.c (xenDaemonDomainSetVcpusFlags): Likewise.

Archipel is a libvirt-based solution to manage and supervise virtual

service or custom protocol. You just need at least one XMPP server,
like eJabberd, to start playing with it. This allows Archipel to
work completely real time. You never have to refresh the user
interface, you'll be notified as soon as something happens. You can
even use your favorite chat clients to command your infrastructure.

<h2><a name="Xen">Xen support</a></h2>
<p>When running in a Xen environment, programs using libvirt have to execute
in "Domain 0", which is the primary Linux OS loaded on the machine. That OS
kernel provides most if not all of the actual drivers used by the set of
domains. It also runs the Xen Store, a database of information shared by the
hypervisor, the backend drivers, any running domains, and libxl (aka libxenlight).
libxl provides a set of APIs for creating and managing domains, which can be used
by applications such as the xl tool provided by Xen or libvirt. The hypervisor,
hypervisor, the kernels, the drivers and the xen daemon. Xend. The xen daemon
supervise the control and execution of the sets of domains. The hypervisor,
drivers, kernels and daemons communicate though a shared system bus
implemented in the hypervisor. The figure below tries to provide a view of
this environment:</p>
<img src="architecture.gif" alt="The Xen architecture" />
<p>The library will interact with libxl for all management operations
on a Xen system.</p>
<p>Note that the libvirt libxl driver only supports root access.</p>
<p>The library can be initialized in 2 ways depending on the level of
privilege of the embedding program. If it runs with root access,
virConnectOpen() can be used, it will use three different ways to connect to
the Xen infrastructure:</p>
<ul>
<li>a connection to the Xen Daemon though an HTTP RPC layer</li>
<li>a read/write connection to the Xen Store</li>
<li>use Xen Hypervisor calls</li>
<li>when used as non-root libvirt connect to a proxy daemon running
as root and providing read-only support</li>
</ul>
<p>The library will usually interact with the Xen daemon for any operation
changing the state of the system, but for performance and accuracy reasons
may talk directly to the hypervisor when gathering state information at
least when possible (i.e. when the running program using libvirt has root
privilege access).</p>
<p>If it runs without root access virConnectOpenReadOnly() should be used to
connect to initialize the library. It will then fork a libvirt_proxy
program running as root and providing read_only access to the API, this is
then only useful for reporting and monitoring.</p>

The storage management APIs are based around 2 core concepts

<li>
<strong>Volume</strong> - a single storage volume which can
be assigned to a guest, or used for creating further pools. A
volume is either a block device, a raw file, or a special format
file.
</li>
<li>
<strong>Pool</strong> - provides a means for taking a chunk
of storage and carving it up into volumes. A pool can be used to
manage things such as a physical disk, a NFS server, a iSCSI target,
a host adapter, an LVM group.
</li>
</ol>
<p>
These two concepts are mapped through to two libvirt objects, a
<code>virStorageVolPtr</code> and a <code>virStoragePoolPtr</code>,
each with a collection of APIs for their management.
