( https://bugzilla.redhat.com/show_bug.cgi?id=1926190 )
However, unless the domain is using user aliases (prefixed ua-),
there are no aliases in the persistent definition.
Only match by MAC/PCI/other addresses in that case, to fix update-device

Originally the default encryption engine is populated in the disk
post-parse callback code. This works for disks but for any additional
images introduced either via the block copy API or via the backup API we
don't populate the default.
In case when the backup or block copy is requested on an encrypted image
this would then lead to an error:
error: internal error: Unexpected enum value 0 for virStorageEncryptionEngine
This patch adds another point where we populate the default which is
when setting up a virStorageSource for actual usage.
We keep the original setting in the post-parse callback as that's the
only point that is recorded in the XML file after definition.

Before commit 73c352ab8c which converted the hostdev commandline
formatter to JSON the 'ramfb' property was formatted only if it was
enabled.
The main reason for that is that enabling 'ramfb' switches the device
model to 'vfio-pci-nohotplug' which actually has the property, while
'vfio-pci' (used when 'ramfb' is disabled or absent) doesn't have it.
Restore the logic to format 'ramfb' only when it's enabled and add a
comment that it's deliberate.

x86Compute() is a static function called only by virCPUx86Compare()

There is no guarantee that QEMU and libvirt have been configured
with the same prefix.
In particular, Homebrew on macOS will pass a different, private
prefix for each package version and then use symlinks to make
the files for a specific version appear in the usual locations.
This works perfectly fine as long as one package doesn't try to
go poking around another package's data - which is exactly what
libvirt needs to do in order to read and parse the QEMU interop
data.
qemu_datadir can now be explicitly provided to make this and
other uncommon scenarios work. The common scenario, where QEMU
and libvirt both use the same prefix, is unaffected.

The upcoming QEMU 6.2.0 implements a new event called
DEVICE_UNPLUG_GUEST_ERROR, a new event that reports generic device
unplug errors that were detected by the guest and reported back to QEMU.
This new event is going to be specially useful for pseries guests that
uses newer kernels (must have kernel commit 29c9a2699e71), which is the
case for Fedora 34 at this moment. These guests have the capability of
reporting CPU removal errors back to QEMU which, starting in 6.2.0, will
emit the DEVICE_UNPLUG_GUEST_ERROR event. Libvirt can use this event to
abort the device removal immediately instead of waiting for 'setvcpus'
timeout.
QEMU 6.2.0 is also going to emit DEVICE_UNPLUG_GUEST_ERROR for memory
hotunplug errors, both in pseries and ACPI guests. QEMU 6.1.0 reports
memory removal errors using the MEM_UNPLUG_ERROR event, which is going to
be deprecated by DEVICE_UNPLUG_GUEST_ERROR in 6.2.0. Given that
Libvirt wasn't handling the MEM_UNPLUG_ERROR event we don't need to
worry about it - adding support to DEVICE_UNPLUG_GUEST_ERROR will be
enough to cover all future cases.
This patch adds support to DEVICE_UNPLUG_GUEST_ERROR by adding the
minimal wiring required for Libvirt to be aware of it. The monitor
callback for this event will abort the pending removal operation of the
device reported by the "device" property of the event. Most of the heavy
lifting is already done by existing code that handles
QEMU_DOMAIN_UNPLUGGING_DEVICE_STATUS_GUEST_REJECTED, making our life
easier to abort the pending removal operation.

Currently, when opening an agent socket the qemuConnectAgent()
increments domain object refcounter and calls qemuAgentOpen()
where the domain object pointer is simply stored inside
_qemuAgent struct. If qemuAgentOpen() fails, then it clears @cb
member only to avoid qemuProcessHandleAgentDestroy() being called
(which decrements the domain object refcounter) and the domain
object refcounter is then decreased explicitly in
qemuConnectAgent().
The same result can be achieved with much cleaner code: increment
the refcounter inside qemuAgentOpen() and drop the dance around
@cb.
Also, the comment in qemuConnectAgent() about holding an extra
reference is not correct. The thread that called
qemuConnectAgent() already holds a reference to the domain
object. No matter how many time the object is locked and unlocked
the reference counter can't be decreased.

Just like qemuMonitorOpen(), hold the domain object locked
throughout the whole time of qemuConnectAgent() and unlock it
only for a brief time of actual connect() (because this is the
only part that has a potential of blocking).
The reason is that qemuAgentOpen() does access domain object
(well, its privateData) AND also at least one argument (@context)
depends on domain object. Accessing these without the lock is
potentially dangerous.
