A VIR_DOMAIN_NET_TYPE_HOSTDEV interface device is really a hostdev
device, which is created by the libxl driver in libxlMakePCIList().
There is no need to create a libxl_device_nic for such hostdev
devices, so skip interfaces of type VIR_DOMAIN_NET_TYPE_HOSTDEV in
libxlMakeNicList().

Libvirt calls cpuArchDriver.compare() while doing guest migration.
We don't have any logic to distinguish between different arm and

Since the ESX storage implements VMFS and iSCSI storage backends and
chooses relevant backend dynamically at runtime, there was a segfault
when issuing vol-info on iSCSI volume due to unimplemented
virStorageGetInfo function. This patch implements that function that was
missing in iSCSI backend and returns expected result without a segfault.

Refactoring in commit id '0c2305b3' resulted in the wrong storage
volume object being passed to the new storageVolDeleteInternal().
It should have passed 'voldef' which is the address found in the
pool->volumes.objs[i] array. By passing 'voldef', the DeleteInternal
code will find and remove the voldef from the volumes.objs[] list.
Add functions parallelsIsAlive, parallelsIsEncrypted,

There is a problem with function parallelsDomainDefineXML. If we
are defining a new domain, then we need to do 2 things: aclually
create a VM in PCS and add new domain to the cached list of domains
_parallelsConn.domains.
This is done in the function parallelsLoadDomains. So call to
virDomainObjListAdd will return a error, because a domain
with the same name and id will already be in the list.

I added this code year ago, instead of implementing ability
to change VNC configuration, which was not trivial, I added
extra call to prlctl, which sets up VNC with auto port, despite
VNC configuration given by a user.
Let's remove this hack, because, first, it doesn't work on the
latest Parallels Cloud Server release (you have to either specify
--vnc-nopasswd option or password). And also has problem with
error handling. If second call to prlctl fails, VM, created by
first call to prlctl, will not be removed.

If qemuDomainBlockResize() is passed a size not on a KiB boundary - that
is passed a size based in bytes (VIR_DOMAIN_BLOCK_RESIZE_BYTES), then
depending on the source format (qcow2 or qed), the value passed must
be on a sector (or 512 byte) boundary. Since other libvirt code quietly
adjusts the capacity values, then do so here as well - of course ensuring
that adjustment still fits.

QEMU commit 5e2ac51 added a boolean '-msg timestamp=[on|off]'
option, which can enable timestamps on errors:
$ qemu-system-x86_64 -msg timestamp=on zghhdorf
2014-04-09T13:25:46.779484Z qemu-system-x86_64: -msg timestamp=on: could
not open disk image zghhdorf: Could not open 'zghhdorf': No such file or
directory
Enable this timestamp if the QEMU binary supports it.
Add a 'log_timestamp' option to qemu.conf for disabling this behavior.
Adds 'quiesced' status into qemuDomainObjPrivate that tracks whether
FSFreeze is requested in the domain.
It modifies error code from qemuDomainSnapshotFSFreeze and
qemuDomainSnapshotFSThaw, so that a caller can know whether the command is
actually sent to the guest agent. If the error is caused before sending a
freeze command, a counterpart thaw command shouldn't be sent either, not to
confuse fsfreeze status tracking.

Some CDROM devices are reported by udev to have an ID_TYPE="generic"
thus it is necessary to check if ID_CDROM is present.
As a side effect, treating ID_TYPE="generic" as a missing ID_TYPE will

This uses the new QEMU_CAPS_HOST_PCI_MULTIDOMAIN capability when
present, for -devivce pci-assign, -device vfio-pci, and -pcidevice.
While creating tests for this new functionality, I noticed that the
xmls for two existing tests had erroneously specified an
until-now-ignored domain="0x0002", so I corrected those two tests, and
also added two failure tests to be sure that we alert users who
attempt to use a non-zero domain with a qemu that doesn't support it.
Quite a long time ago, (apparently between qemu 0.12 and 0.13) qemu
quietly began supporting the optional specification of a domain in the
host-side address of all pci passthrough commands (by simply
prepending it to the bus:slot.function format, as
"dddd:bb:ss.f"). Since machines with multiple PCI domains are very
rare, this never came up in practice, so libvirt was never updated to
support it.
This patch takes the first step to supporting specification of a non-0
domain in the host-side address of PCI devices being assigned to a
domain, by adding a capability bit to indicate support
"QEMU_CAPS_HOST_PCI_MULTIDOMAIN", and detect it. Since this support
was added in a version prior to the minimum version required for
QMP-style capabilities detection, the capability is always enabled for
any qemu that uses QMP for capabilities detection. For older qemus,
the only clue that a domain can be specified in the host pci address
is the presence of the string "[seg:]" in the help string for
-pcidevice. (Ironically, libvirt will not be modified to support
specification of domain for -pcidevice, since any qemu new enough for
us to care about also supports "-device pci-assign" or "-device
vfio-pci", which are greatly preferred).
When creating a new volume, it is possible to copy data into it from
another already existing volume (referred to as @origvol). Obviously,
the read-only access to @origvol is required, which is thread safe
(probably not performance-wise though). However, with current code
both @newvol and @origvol are marked as building for the time of
copying data from the @origvol to @newvol. The rationale behind
is to disallow some operations on both @origvol and @newvol, e.g.
vol-wipe, vol-delete, vol-download. While it makes sense to not allow
such operations on partly copied mirror, but it doesn't make sense to
disallow vol-create or vol-download on the source (@origvol).

All callers of virStorageFileGetMetadataFromBuf were first calling
virStorageFileProbeFormatFromBuf, to learn what format to pass in.
But this function is already wired to do the exact same probe if
the incoming format is VIR_STORAGE_FILE_AUTO, so it's simpler to
just refactor the probing into the central function.
* src/util/virstoragefile.h (virStorageFileGetMetadataFromBuf):
Drop parameter.
(virStorageFileProbeFormatFromBuf): Drop declaration.
* src/util/virstoragefile.c (virStorageFileGetMetadataFromBuf):
Do probe here instead of in callers.
(virStorageFileProbeFormatFromBuf): Make static.
* src/libvirt_private.syms (virstoragefile.h): Drop function.
* src/storage/storage_backend_fs.c (virStorageBackendProbeTarget):

Add a helper function virBhyveGetDomainTotalCpuStats() to
obtain process CPU time using kvm (kernel memory interface)
and use it to set cpuTime field of the virDomainInfo struct in
bhyveDomainGetInfo().
Instead of guessing it from the interface name, look into
/proc/net/vlan/<interface>.
This works for devices not named <real_device>.<vlan ID>,
avoiding an error flood when virt-manager keeps asking about
them every second:
https://bugzilla.redhat.com/show_bug.cgi?id=966329
This fixes link failures like:
CCLD virfirewalltest
/usr/bin/ld: virfirewalltest-virfirewalltest.o: undefined reference to
symbol 'dbus_message_iter_init_append'
When building packages in a clean chroot the QEMU_USER and QEMU_GROUP
don't exist making VirQemuDriverConfigNew fail with privileged=true.
Avoid that by not requiring privileged mode upfront but setting it later
so we skip the user/group existence check.
This solution was suggested by Daniel P. Berrange and tested by Martin
Kletzander.
Commit id 'ac9a0963' refactored out the 'withCapacity' for the
virStorageBackendUpdateVolInfo() API. See:
http://www.redhat.com/archives/libvir-list/2014-April/msg00043.html
This resulted in a difference in how 'virsh vol-info --pool <poolName>
<volume>' or 'virsh vol-list vol-list --pool <poolName> --details' outputs
the capacity information for a directory pool with a qcow2 sparse file.
For example, using the following XML
mkdir /home/TestPool
cat testpool.xml
<pool type='dir'>
<name>TestPool</name>
<uuid>6bf80895-10b6-75a6-6059-89fdea2aefb7</uuid>
<source>
</source>
<target>
<path>/home/TestPool</path>
<permissions>
<mode>0755</mode>
<owner>0</owner>
<group>0</group>
</permissions>
</target>
</pool>
virsh pool-create testpool.xml
virsh vol-create-as --pool TestPool temp_vol_1 \
--capacity 1048576 --allocation 1048576 --format qcow2
virsh vol-info --pool TestPool temp_vol_1
Results in listing a Capacity value. Prior to the commit, the value would
be '1.0 MiB' (1048576 bytes). However, after the commit the output would be
(for example) '192.50 KiB', which for my system was the size of the volume
in my file system (eg 'ls -l TestPool/temp_vol_1' results in '197120' bytes
or 192.50 KiB). While perhaps technically correct, it's not necessarily
what the user expected (certainly virt-test didn't expect it).
This patch restores the code to not update the target capacity for this path
