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

and documentation updated.

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.

Tooling
=======
libvirt includes support for some useful development tools right in its source
repository, meaning users will be able to take advantage of them without
little or no configuration. Examples include:
- color_coded <https://github.com/jeaye/color_coded>, a vim plugin for
libclang-powered semantic syntax highlighting;
- YouCompleteMe <http://valloric.github.io/YouCompleteMe/>, a vim plugin for
libclang-powered semantic code completion.
Naming conventions
==================
When reading libvirt code, a number of different naming conventions will be
evident due to various changes in thinking over the course of the project's
lifetime. The conventions documented below should be followed when creating
any entirely new files in libvirt. When working on existing files, while it is
desirable to apply these conventions, keeping a consistent style with existing
code in that particular file is generally more important. The overall guiding
principal is that every file, enum, struct, function, macro and typedef name
must have a 'vir' or 'VIR' prefix. All local scope variable names are exempt,
and global variables are exempt, unless exported in a header file.
*File names*
File naming varies depending on the subdirectory. The preferred style is to
have a 'vir' prefix, followed by a name which matches the name of the
functions / objects inside the file. For example, a file containing an object
'virHashtable' is stored in files 'virhashtable.c' and 'virhashtable.h'.
Sometimes, methods which would otherwise be declared 'static' need to be
exported for use by a test suite. For this purpose a second header file should
be added with a suffix of 'priv', e.g. 'virhashtablepriv.h'. Use of
underscores in file names is discouraged when using the 'vir' prefix style.
The 'vir' prefix naming applies to src/util, src/rpc and tests/ directories.
Most other directories do not follow this convention.
*Enum type & field names*
All enums should have a 'vir' prefix in their typedef name, and each following
word should have its first letter in uppercase. The enum name should match the
typedef name with a leading underscore. The enum member names should be in all
uppercase, and use an underscore to separate each word. The enum member name
prefix should match the enum typedef name.
typedef enum _virSocketType virSocketType;
enum _virSocketType {
VIR_SOCKET_TYPE_IPV4,
VIR_SOCKET_TYPE_IPV6,
};
*Struct type names*
All structs should have a 'vir' prefix in their typedef name, and each
following word should have its first letter in uppercase. The struct name
should be the same as the typedef name with a leading underscore. A second
typedef should be given for a pointer to the struct with a 'Ptr' suffix.
typedef struct _virHashTable virHashTable;
typedef virHashTable *virHashTablePtr;
struct _virHashTable {
...
};
*Function names*
All functions should have a 'vir' prefix in their name, followed by one or
more words with first letter of each word capitalized. Underscores should not
be used in function names. If the function is operating on an object, then the
function name prefix should match the object typedef name, otherwise it should
match the filename. Following this comes the verb / action name, and finally
an optional subject name. For example, given an object 'virHashTable', all
functions should have a name 'virHashTable$VERB' or
'virHashTable$VERB$SUBJECT", e.g. 'virHashTableLookup' or
'virHashTableGetValue'.
*Macro names*
All macros should have a "VIR" prefix in their name, followed by one or more
uppercase words separated by underscores. The macro argument names should be
in lowercase. Aside from having a "VIR" prefix there are no common practices
for the rest of the macro name.

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)
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>
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, using the `git send-email` command. Further guidance on this
can be found in the `HACKING` file, or the project website
* <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
* <https://libvirt.org/contact.html>

libvirtd - libvirtd management daemon
=head1 SYNOPSIS
B<libvirtd> [I<OPTION>]...
=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.

# flaws and should no longer be used. Thus GSSAPI is now the default.

<h1>Storage management architecture</h1>
<p>
The storage management APIs are based around 2 core concepts
</p>
<ol>
<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.

<h2><a name="ACL_server_sasl">SASL pluggable authentication</a></h2>
<h2><a name="ACL_server_username">Username/password auth</a></h2>
<p>
Libvirt integrates with the cyrus-sasl library to provide a pluggable authentication
system using the SASL protocol. SASL can be used in combination with libvirtd's TLS
or TCP socket listeners. When used with the TCP listener, the SASL mechanism is
rqeuired to provide session encryption in addition to authentication. Only a very
few SASL mechanisms are able to do this, and of those that can do it, only the
GSSAPI plugin is considered acceptably secure by modern standards:
</p>
<dl>
<dt>GSSAPI</dt>
<dd><strong>This is the current default mechanism to use with libvirtd</strong>.
It uses the Kerberos v5 authentication protocol underneath, and assuming
the Kerberos client/server are configured with modern ciphers (AES),
it provides strong session encryption capabilities.</dd>
<dt>DIGEST-MD5</dt>
<dd>This was previously set as the default mechanism to use with libvirtd.
It provides a simple username/password based authentication mechanism
that includes session encryption.
<a href="https://tools.ietf.org/html/rfc6331">RFC 6331</a>, however,
documents a number of serious security flaws with DIGEST-MD5 and as a
result marks it as <code>OBSOLETE</code>. Specific concerns are that
it is vulnerable to MITM attacks and the MD5 hash can be brute-forced
to reveal the password. A replacement is provided via the SCRAM mechanism,
however, note that this does not provide encryption, so the SCRAM
mechanism can only be used on the libvirtd TLS listener.
</dd>
<dt>PASSDSS-3DES-1</dt>
<dd>This provides a simple username/password based authentication
mechanism that includes session encryption. The current cyrus-sasl
implementation does not provide a way to validate the server's
public key identity, thus it is susceptible to a MITM attacker
impersonating the server. It is also not enabled in many OS
distros when building SASL libraries.</dd>
<dt>KERBEROS_V4</dt>
<dd>This uses the obsolete Kerberos v4 protocol to provide both authentication
and session encryption. Kerberos v4 protocol has been obsolete since the
early 1990's and has known security vulnerabilities so this will never be
used in practice.</dd>
</dl>
<p>
Other SASL mechanisms, not listed above, can only be used when the libvirtd
TLS or UNIX socket listeners.
</p>
<h3><a name="ACL_server_username">Username/password auth</a></h3>
<p>
As noted above, the DIGEST-MD5 mechanism is considered obsolete and should
not be used anymore. To provide a simple username/password auth scheme on
the libvirt UNIX socket or TLS listeners, however, it is possible to use
the SCRAM mechanism. The <code>auth_unix_ro</code>, <code>auth_unix_rw</code>,
<code>auth_tls</code> config params in <code>libvirt.conf</code> can be used
to turn on SASL auth in these listeners.
</p>
<p>
Since the libvirt SASL config file defaults to using GSSAPI (Kerberos), a
config change is rquired to enable plain password auth. This is done by
editting <code>/etc/sasl2/libvirt.conf</code> to set the <code>mech_list</code>
parameter to <code>scram-sha-1</code>.
</p>
The plain TCP socket of the libvirt daemon defaults to using SASL for authentication.
The SASL mechanism configured by default is DIGEST-MD5, which provides a basic
username+password style authentication. It also provides for encryption of the data
stream, so the security of the plain TCP socket is on a par with that of the TLS
socket. If desired the UNIX socket and TLS socket can also have SASL enabled by
setting the <code>auth_unix_ro</code>, <code>auth_unix_rw</code>, <code>auth_tls</code>
config params in <code>libvirt.conf</code>.
</p>
<p>
Out of the box, no user accounts are defined, so no clients will be able to authenticate
on the TCP socket. Adding users and setting their passwords is done with the <code>saslpasswd2</code>

The libvirt SASL config also defaults to GSSAPI, so there is no need to edit the

The plain TCP socket of the libvirt daemon defaults to using SASL for authentication.
The SASL mechanism configured by default is DIGEST-MD5, which provides a basic
username+password style authentication. To enable Kerberos single-sign-on instead,
the libvirt SASL configuration file must be changed. This is <code>/etc/sasl2/libvirt.conf</code>.
The <code>mech_list</code> parameter must first be changed to <code>gssapi</code>
instead of the default <code>digest-md5</code>, and keytab should be set to
<code>/etc/libvirt/krb5.tab</code> . If SASL is enabled on the UNIX
and/or TLS sockets, Kerberos will also be used for them. Like DIGEST-MD5, the Kerberos

<h1>Contributing to libvirt</h1>
<p>
This page provides guidance on how to contribute to the
libvirt project
</p>
<ul id="toc"></ul>
<h2><a name="skills">Contributions required</a></h2>
<p>
The libvirt project is always looking for new contributors to
participate in ongoing activities. While code development is a
major part of the project, assistance is needed in many other
areas including documentation writing, bug triage, testing,
application integration, website / wiki content management,
translation, branding, social media and more. The only
requirement is an interest in virtualization and desire to
help.
</p>
<p>
The following is a non-exhaustive list of areas in which
people can contribute to libvirt. If you have ideas for
other contributions feel free to follow them.
</p>
<ul>
<li><strong>Software development</strong>. The core library / daemon (and
thus the bulk of coding) is written in C, but there are
language bindings written in Python, Perl, Java, Ruby,
Php, OCaml and Go. There are also higher level wrappers
mapping libvirt into other object frameworks, such GLib,
CIM and SNMP</li>
<li><strong>Translation</strong>. All the libvirt modules aim to support
translations where appropriate. All translation is
handling outside of the normal libvirt review process,
using the <a href="http://fedora.zanata.org">Fedora
instance</a> of the Zanata tool. Thus people wishing
to contribute to translation should join the Fedora
translation team</li>
<li><strong>Documentation</strong>. There are docbook guides on various
aspects of libvirt, particularly application development
guides for the C library and Python, and a virsh command
reference. There is thus scope for work by people who are
familiar with using or developing against libvirt, to
write further content for these guides. There is also a
need for people to review existing content for copy editing
and identifying gaps in the docs</li>
<li><strong>Website / wiki curation</strong>. The bulk of the website is
maintained in the primary GIT repository, while the wiki
site uses mediawiki. In both cases there is a need for
people to both write new content and curate existing
content to identify outdated information, improve its
organization and target gaps.</li>
<li><strong>Testing</strong>. There are a number of tests suites that can run
automated tests against libvirt. The coverage of the tests
is never complete, so there is a need for people to create
new test suites and / or provide environments to actually
run the tests in a variety of deployment scenarios.</li>
<li><strong>Code analysis</strong>. The libvirt project has access to the coverity
tool to run static analysis against the codebase, however,
there are other types of code analysis that can be useful.
In particular fuzzing of the inputs can be very effective
at identifying problematic edge cases.</li>
<li><strong>Security handling</strong>. Downstream (operating system) vendors
who distribute libvirt may wish to propose a person to
be part of the security handling team, to get early access
to information about forthcoming vulnerability fixes.</li>
<li><strong>Evangalism</strong>. Work done by the project is of no benefit
unless the (potential) user community knows that it
exists. Thus it is critically important to the health
and future growth of the project, that there are a people
who evangalise the work created by the project. This can
take many forms, writing blog posts (about usage of features,
personal user experiances, areas for future work, and more),
syndicating docs and blogs via social media, giving user
group and/or conference talks about libvirt.</li>
<li><strong>User assistance</strong>. Since documentation
is never perfect, there are inevitably cases where users
will struggle to attain a deployment goal they have, or
run into trouble with managing an existing deployment.
While some users may be able to contact a software vendor
to obtain support, it is common to rely on community help
forums such as <a href="contact.html#email">libvirt users
mailing list</a>, or sites such as
<a href="http://stackoverflow.com/questions/tagged/libvirt">stackoverflow.</a>
People who are familiar with libvirt and have ability &amp;
desire to help other users are encouraged to participate in
these help forums.</li>
</ul>
<h2><a name="comms">Communication</a></h2>
<p>
For full details on contacting other project contributors
read the <a href="contact.html">contact</a> page. There
are two main channels that libvirt uses for communication
between contributors:
</p>
<h3><a name="email">Mailing lists</a></h3>
<p>
The project has a number of
<a href="contact.html#email">mailing lists</a> for
general communication between contributors.
In general any design discussions and review
of contributions will take place on the mailing
lists, so it is important for all contributors
to follow the traffic.
</p>
<h3><a name="irc">Instant messaging / chat</a></h3>
<p>
Contributors to libvirt are encouraged to join the
<a href="contact.html#irc">IRC channel</a> used by
the project, where they can have live conversations
with others members.
</p>
<h2><a name="outreach">Student / outreach coding programs</a></h2>
<p>
Since 2016, the libvirt project directly participates as an
organization in the <a href="http://wiki.libvirt.org/page/Google_Summer_of_Code_Ideas">Google Summer of Code program</a>. Prior to
this the project had a number of students in the program
via a joint application with the QEMU project. People are
encouraged to look at both the libvirt and QEMU programs
to identify potentially interesting projects to work on.

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

<h1>libvirt Application Development Guides</h1>
<h1>libvirt Application Development Guide</h1>
<ul id="toc"></ul>
<p>
The libvirt API is accessible from a number of programming languages.
At this time, there are application development guides available
which cover the C API and the Python API. Of the two, the Python guide
is currently the more comprehensive document.
The guide is both a learning tool for developing with libvirt and an
API reference document. It is a work in progress, composed by a
professional author from contributions written by members of the
libvirt team.
</p>
<p>
Contributions to the guide are <b>VERY</b> welcome. If you'd like to get
your name on this and demonstrate your virtualisation prowess, a solid
contribution to the content here will do it. :)

<h2><a name="schedule">Primary release schedule</a></h2>
<p>
The core libvirt module follows a time based plan, with releases made
once a month on the 1st of each month give or take a few days. The only
exception is at the start of the year where there are two 6 weeks gaps
(first release in the middle of Jan, then skip the Feb release), giving
a total of 11 releases a year. The Python and Perl modules will aim to
release at the same time as the core libvirt module. Other modules have
independant ad-hoc releases with no fixed time schedle.
</p>
<h2><a name="numbering">Release numbering</a></h2>
<p>
Since libvirt 2.0.0, a time based version numbering rule
is applied to the core library releases. As such, the changes
in version number have do not have any implications with respect
to the scope of features or bugfixes included, the stability of
the code, or the API / ABI compatibility (libvirt API / ABI is
guaranteed stable forever). The rules applied for changing the
libvirt version number are:
</p>
<dl>
<dt><code>major</code></dt>
<dd>incremented by 1 for the first release of the year (the
Jan 15th release)</dd>
<dt><code>minor</code></dt>
<dd>reset to 0 with every major increment, otherwise incremented by 1
for each monthly release from git master</dd>
<dt><code>micro</code></dt>
<dd>always 0 for releases from git master, incremented by 1
for each stable maintenance release</dd>
</dl>
<p>
Prior to 2.0.0, the major/minor numbers were incremented
fairly arbitrarily, and maintenance releases appended a
fourth digit. The language bindings will aim to use the
same version number as the most recent core library API
they support. The other modules have their own distinct
release numbering sequence, though they generally aim
to follow the above rules for incrementing major/minor/micro
digits.
</p>
<h2><a name="maintenance">Maintenance releases</a></h2>
<p>
In the git repository are several stable maintenance branches
for the core library, matching the
pattern <code>v<i>major</i>.<i>minor</i>-maint</code>;
In the git repository are several stable maintenance branches,
matching the
pattern <code>v<i>major</i>.<i>minor</i>.<i>micro</i>-maint</code>;
these branches are forked off the corresponding
<code>v<i>major</i>.<i>minor</i>.0</code> formal
<code>v<i>major</i>.<i>minor</i>.<i>micro</i></code> formal
release, and may have further releases of the
form <code>v<i>major</i>.<i>minor</i>.<i>micro</i></code>.
form <code>v<i>major</i>.<i>minor</i>.<i>micro</i>.<i>rel</i></code>.
These maintenance branches should only contain bug fixes, and no
new features, backported from the master branch, and are
supported as long as at least one downstream distribution
expresses interest in a given branch. These maintenance
branches are considered during CVE analysis. In contrast
to the primary releases which are made once a month, there
is no formal schedule for the maintenance releases, which
are made whenever there is a need to make available key
bugfixes to downstream consumers. The language bindings
and other modules generally do not provide stable branch
releases.

<h1>Host device management</h1>
<p>
Libvirt provides management of both physical and virtual host devices
(historically also referred to as node devices) like USB, PCI, SCSI, and
network devices. This also includes various virtualization capabilities
which the aforementioned devices provide for utilization, for example
SR-IOV, NPIV, MDEV, DRM, etc.
</p>
<p>
The node device driver provides means to list and show details about host
devices (<code>virsh nodedev-list</code>,
<code>virsh nodedev-dumpxml</code>), which are generic and can be used
with all devices. It also provides means to create and destroy devices
(<code>virsh nodedev-create</code>, <code>virsh nodedev-destroy</code>)
which are meant to be used to create virtual devices, currently only
supported by NPIV
(<a href="http://wiki.libvirt.org/page/NPIV_in_libvirt">more info about NPIV)</a>).
Devices on the host system are arranged in a tree-like hierarchy, with
the root node being called <code>computer</code>. The node device driver
supports two backends to manage the devices, HAL and udev, with the former
being deprecated in favour of the latter.
</p>
<p>
The generic format of a host device XML can be seen below.
To identify a device both within the host and the device tree hierarchy,
the following elements are used:
</p>
<dl>
<dt><code>name</code></dt>
<dd>
The device's name will be generated by libvirt using the subsystem,
like pci and the device's sysfs basename.
</dd>
<dt><code>path</code></dt>
<dd>
Fully qualified sysfs path to the device.
</dd>
<dt><code>parent</code></dt>
<dd>
This element identifies the parent node in the device hierarchy. The
value of the element will correspond with the device parent's
<code>name</code> element or <code>computer</code> if the device does
not have any parent.
</dd>
<dt><code>driver</code></dt>
<dd>
This elements reports the driver in use for this device. The presence
of this element in the output XML depends on whether the underlying
device manager (most likely udev) exposes information about the
driver.
</dd>
<dt><code>capability</code></dt>
<dd>
Describes the device in terms of feature support. The element has one
mandatory attribute <code>type</code> the value of which determines
the type of the device. Currently recognized values for the attribute
are:
<code>system</code>,
<code>pci</code>,
<code>usb</code>,
<code>usb_device</code>,
<code>net</code>,
<code>scsi</code>,
<code>scsi_host</code> (<span class="since">Since 0.4.7</span>),
<code>fc_host</code>,
<code>vports</code>,
<code>scsi_target</code> (<span class="since">Since 0.7.3</span>),
<code>storage</code> (<span class="since">Since 1.0.4</span>),
<code>scsi_generic</code> (<span class="since">Since 1.0.7</span>),
<code>drm</code> (<span class="since">Since 3.1.0</span>), and
<code>mdev</code> (<span class="since">Since 3.4.0</span>).
This element can be nested in which case it further specifies a
device's capability. Refer to specific device types to see more values
for the <code>type</code> attribute which are exclusive.

<p>
The XML format for a PCI device stays the same for any further
capabilities it supports, a single nested <code>&lt;capability&gt;</code>
element will be included for each capability the device supports.
</p>
<h3><a name="SRIOVCap">SR-IOV capability</a></h3>
<p>
Single root input/output virtualization (SR-IOV) allows sharing of the
PCIe resources by multiple virtual environments. That is achieved by
slicing up a single full-featured physical resource called physical
function (PF) into multiple devices called virtual functions (VFs) sharing
their configuration with the underlying PF. Despite the SR-IOV
specification, the amount of VFs that can be created on a PF varies among
manufacturers.
</p>
<p>
Suppose the NIC <a href="#PCI">above</a> was also SR-IOV capable, it would
also include a nested
<code>&lt;capability&gt;</code> element enumerating all virtual
functions available on the physical device (physical port) like in the
example below.
</p>
<pre>
&lt;capability type='pci'&gt;
...
&lt;capability type='virt_functions' maxCount='7'&gt;
&lt;address domain='0x0000' bus='0x04' slot='0x10' function='0x1'/&gt;
&lt;address domain='0x0000' bus='0x04' slot='0x10' function='0x3'/&gt;
&lt;address domain='0x0000' bus='0x04' slot='0x10' function='0x5'/&gt;
&lt;address domain='0x0000' bus='0x04' slot='0x10' function='0x7'/&gt;
&lt;address domain='0x0000' bus='0x04' slot='0x11' function='0x1'/&gt;
&lt;address domain='0x0000' bus='0x04' slot='0x11' function='0x3'/&gt;
&lt;address domain='0x0000' bus='0x04' slot='0x11' function='0x5'/&gt;
&lt;/capability&gt;
...
&lt;/capability&gt;</pre>
<p>
A SR-IOV child device on the other hand, would then report its top level
capability type as a <code>phys_function</code> instead:
</p>
<pre>
&lt;device&gt;
...
&lt;capability type='phys_function'&gt;
&lt;address domain='0x0000' bus='0x04' slot='0x00' function='0x0'/&gt;
&lt;/capability&gt;
...
&lt;device&gt;</pre>
<h3><a name="MDEVCap">MDEV capability</a></h3>
<p>
A PCI device capable of creating mediated devices will include a nested
capability <code>mdev_types</code> which enumerates all supported mdev
types on the physical device, along with the type attributes available
through sysfs:
</p>
<dl>
<dt><code>type</code></dt>
<dd>
This element describes a mediated device type which acts as an
abstract template defining a resource allocation for instances of this
device type. The element has one attribute <code>id</code> which holds
an official vendor-supplied identifier for the type.
<span class="since">Since 3.4.0</span>
</dd>
<dt><code>name</code></dt>
<dd>
The <code>name</code> element holds a vendor-supplied code name for
the given mediated device type. This is an optional element.
<span class="since">Since 3.4.0</span>
</dd>
<dt><code>deviceAPI</code></dt>
<dd>
The value of this element describes how an instance of the given type
will be presented to the guest by the VFIO framework.
<span class="since">Since 3.4.0</span>
</dd>
<dt><code>availableInstances</code></dt>
<dd>
This element reports the current state of resource allocation. In other
words, how many instances of the given type can still be successfully
created on the physical device.
<span class="since">Since 3.4.0</span>
</dd>
</dl>
<p>
For a more info about mediated devices, refer to the
<a href="#MDEV">paragraph below</a>.
</p>

&lt;/type&gt;
&lt;!-- Here would come the rest of the available mdev types --&gt;
&lt;/capability&gt;
...
&lt;/capability&gt;
&lt;/device&gt;</pre>
<h2><a name="MDEV">Mediated devices (MDEVs)</a></h2>
<p>
Mediated devices (<span class="since">Since 3.2.0</span>) are software
devices defining resource allocation on the backing physical device which
in turn allows the parent physical device's resources to be divided into
several mediated devices, thus sharing the physical device's performance
among multiple guests. Unlike SR-IOV however, where a PCIe device appears
as multiple separate PCIe devices on the host's PCI bus, mediated devices
only appear on the mdev virtual bus. Therefore, no detach/reattach
procedure from/to the host driver procedure is involved even though
mediated devices are used in a direct device assignment manner.
</p>
<p>
The following sub-elements and attributes are exposed within the
<code>capability</code> element:
</p>
<dl>
<dt><code>type</code></dt>
<dd>
This element describes a mediated device type which acts as an
abstract template defining a resource allocation for instances of this
device type. The element has one attribute <code>id</code> which holds
an official vendor-supplied identifier for the type.
<span class="since">Since 3.4.0</span>
</dd>
<dt><code>iommuGroup</code></dt>
<dd>
This element supports a single attribute <code>number</code> which holds
the IOMMU group number the mediated device belongs to.
<span class="since">Since 3.4.0</span>
</dd>
</dl>
<h3>Example of a mediated device</h3>
<pre>
&lt;device&gt;
&lt;name&gt;mdev_4b20d080_1b54_4048_85b3_a6a62d165c01&lt;/name&gt;
&lt;path&gt;/sys/devices/pci0000:00/0000:00:02.0/4b20d080-1b54-4048-85b3-a6a62d165c01&lt;/path&gt;
&lt;parent&gt;pci_0000_06_00_0&lt;/parent&gt;
&lt;driver&gt;
&lt;name&gt;vfio_mdev&lt;/name&gt;
&lt;/driver&gt;
&lt;capability type='mdev'&gt;
&lt;type id='nvidia-11'/&gt;
&lt;iommuGroup number='12'/&gt;
&lt;capability/&gt;
&lt;device/&gt;</pre>
<p>
The support of mediated device's framework in libvirt's node device driver
covers the following features:
</p>
<ul>
<li>
list available mediated devices on the host
(<span class="since">Since 3.4.0</span>)
</li>
<li>
display device details
(<span class="since">Since 3.4.0</span>)
</li>
</ul>
<p>
Because mediated devices are instantiated from vendor specific templates,
simply called 'types', information describing these types is contained
within the parent device's capabilities
(see the example in <a href="#PCI">PCI host devices</a>).
</p>
<p>
To see the supported mediated device types on a specific physical device
use the following:
</p>
<pre>
$ ls /sys/class/mdev_bus/&lt;device&gt;/mdev_supported_types</pre>
<p>
To manually instantiate a mediated device, use one of the following as a
reference:
</p>
<pre>
$ uuidgen &gt; /sys/class/mdev_bus/&lt;device&gt;/mdev_supported_types/&lt;type&gt;/create
...
$ echo &lt;UUID&gt; &gt; /sys/class/mdev_bus/&lt;device&gt;/mdev_supported_types/&lt;type&gt;/create</pre>
<p>
Manual removal of a mediated device is then performed as follows:
</p>
<pre>
$ echo 1 &gt; /sys/bus/mdev/devices/&lt;uuid&gt;/remove</pre>

the CPU can be different from the one shown in host capabilities XML.
This is indicated by the <code>fallback</code> attribute of the

<dd>The <code>address</code> attribute defines an IPv4 address in
dotted-decimal format, or an IPv6 address in standard colon-separated
hexadecimal format, that will be configured on the bridge device
associated with the virtual network. To the guests this IPv4 address
will be their IPv4 default route. For IPv6, the default route is
established via Router Advertisement. For IPv4 addresses, the
<code>netmask</code> attribute defines the significant bits of the
network address, again specified in dotted-decimal format. For IPv6
addresses, and as an alternate method for IPv4 addresses, the
significant bits of the network address can be specified with the
<code>prefix</code> attribute, which is an integer (for example,
<code>netmask='255.255.255.0'</code> could also be given as
<code>prefix='24'</code>). The <code>family</code> attribute is used
to specify the type of address &mdash; <code>ipv4</code> or
<code>ipv6</code>; if no <code>family</code> is given,
<code>ipv4</code> is assumed. More than one address of each family can
be defined for a network. The optional <code>localPtr</code> attribute
(<span class="since">since 3.0.0</span>) configures the DNS server to
not forward any reverse DNS requests for IP addresses from the network
configured by the <code>address</code> and
<code>netmask</code>/<code>prefix</code> attributes. For some unusual
network prefixes (not divisible by 8 for IPv4 or not divisible by 4 for
IPv6) libvirt may be unable to compute the PTR domain automatically.
The <code>ip</code> element is supported <span class="since">since

attribute, which is an integer (for example, <code>netmask='255.255.255.0'</code>
could also be given as <code>prefix='24'</code>. The <code>family</code>
attribute is used to specify the type of address - 'ipv4' or 'ipv6'; if no
<code>family</code> is given, 'ipv4' is assumed. A network can have more than
one of each family of address defined, but only a single IPv4 address can have a
