Commit 271940223c which strived to add
support to use '--uuid' in the table output of 'virsh list' went too far
and also allowed the default table view to be enabled when just '--uuid'
is specified.
This broke the script-friendly output which previously had this format:
$ virsh list --uuid
b6d03c07-86f8-4a57-8719-172a5d0359bb
to this script-unfriendly output:
$ virsh list --uuid
Id Name State UUID
-------------------------------------------------------------
1 ha running b6d03c07-86f8-4a57-8719-172a5d0359bb
Using the human friendly output will still be possible by using:
$ virsh list --table --uuid

The 'nfs-utils' package provides 'showmount' used to detect NFS-based
storage pool sources. As the lookup of storage pool sources can fail
gracefully and does so e.g. if the gluster backend is not installed we
can do the same for NFS.
Apart from allowing a tighter footprint when installing libvirt, this
also allows installation of the storage driver core in cases when a
security policy prohibits use of NFS.

pvpanic-pci is the only reasonable implementation of a panic
device for aarch64/virt guests. Right now we're asking users to
provide the model name manually, but we can be more helpful and
fill it in automatically instead.
With this change, the aarch64-panic-no-model test no longer
fails and so it's no longer useful to us. Instead, we can amend
the aarch64-virt-default-models test case to include panic
coverage, something that until now wasn't possible.

Right now the fallback behavior is to use MODEL_ISA if we
haven't been able to find a better match, but that's not very
useful as we're still going to hit an error later, when
QEMU_CAPS_DEVICE_PANIC is not found at Validate time.
Instead of doing that, allow MODEL_DEFAULT to get all the
way to Validate and report an error upon encountering it.

The refactor of 'udevListInterfacesByStatus()' which attempted to make
it usable as backend for 'udevNumOfInterfacesByStatus()' neglected to
consider the corner case of 'g_new0(..., 0)' returning NULL if the user
actually requests 0 elements.
As the code was modified to report the full number of interfaces in the
system when the list of names is NULL, the RPC code would be asked to
serialize a NULL-list of interface names with declared lenth of 1+
causing a crash.
To fix this corner case we make callers pass '-1' as @names_len (it's
conveniently an 'int' due to RPC type usage) if they don't wish to fetch
the actual list and convert all decisions to be done on @names_len being
non-negative instead of @names being non-NULL.

It's possible to hit the following situation during qemu p2p live
migration:
1. qemu has live migrated and exited (making virDomainObjIsActive()
return false)
2. the live migration job is still in progress, waiting for a
confirmation from the remote libvirt daemon. This may last for
a while with a presence of networking issues (up to keepalive
timeout).
Any attempt to start the domain again would fail with "domain is already
being started" message which is misleading in this situation as it
doesn't reflect what's really happening.
Add a check for the migration job and report a different error message
if the migration job is still running.

Currently, qemuProcessStop() unlocks given domain object right in
the middle of cleanup process. This is dangerous because there
might be another thread which is executing virDomainObjListAdd().
And since the domain object is on the list of domain objects AND
by the time qemuProcessStop() unlocks it the object is also
marked as inactive, the other thread acquires the lock and
switches vm->def pointer.
The unlocking of domain object is needed though, to allow even
processing thread finish its queue. Well, the processing can be
done before any cleanup is attempted.
Therefore, use freshly introduced virEventThreadStop() to join
the event thread and drop lock/unlock from the middle of
qemuProcessStop().
Now, there's a comment being removed that mentions
qemuDomainObjStopWorker() and why it has to be called only after
the domain is marked as dead. This comment is no longed
applicable because call to qemuDomainObjStopWorker() is removed
also. Moreover, priv->beingDestroyed is set to true before
unlocking the domain object, thus any event processing callback
is going to see the domain being destroyed and can chose to
either exit early or finish processing event.

as produced by libvirt. This also tests the transformation from libvirt's
internal state to the aforementioned canonical form and to a QEMU

As a bonus, we also test some known bad configurations:
- When user explicitly adds ps2 bus inputs, but also explicitly disables
the 'ps2' feature.
- When user explicitly enables the 'vmport' feature, but also explicitly
disables the 'ps2' feature. This is not supported by QEMU and will
result in vmport device not being created without emitting any warning

A notable side effect of disabling the i8042 controller in QEMU is that
the vmport device won't be created. For this reason we will not allow
