2ddff1cc40 storage_source: Add flag storing whether threshold event was registered with index
When users register the threshold event for the top level image with an
explicit index (e.g. vda[3]) they are clearly expecting the index in the
event.

This flag will help avoiding emission of the second event without the
index when the client clearly requested one with the index.

11fcf054e6 qemu: remove default audio backend for migratable XML
When seeing a guest with a sound device, and no audio backend, we
automatically add an audio backend XML element based on the historical
QEMU driver behaviour. Unfortunately when we live migrate back to an
old libvirt, it may not understand the audio driver type we configured.
We thus need to strip the default audio backend when migrating.

c6d7b9a261 qemu: Don't use memory-backend-memfd for NVDIMMs
If guest is configured to use memfd then the function that build
memory-backend-* part of command line will put
memory-backend-memfd, always. Even for NVDIMMs. This is not
correct, because NVDIMMs need a backing path (usually to a real
host NVDIMM device). Therefore, regardless of memfd being
requested, we have to stick with memory-backend-file.

cda47bac25 virDomainMachineNameAppendValid: Handle special characters better
When constructing guest name for machined we have to be very
cautious as machined expects a name that's basically a valid URI.
Therefore, if there's a dot it has to be followed by a letter or
a number. And if there's a sequence of two or more dashes they
should be joined into a single dash. These rules are implemented
in virDomainMachineNameAppendValid(). There's the @skip variable
which is supposed to track whether it is safe to append a dot or
a dash into name. However, the variable is set to false (meaning
it is safe to append a dot or a dash) even if the current
character we are processing is not in the set of allowed
characters (and thus skipped over).

e9b534905f nodedev: handle mdevs from multiple parents
Due to a rather unfortunate misunderstanding, we were parsing the list
of defined devices from mdevctl incorrectly. Since my primary
development machine only has a single device capable of mdevs, I
apparently neglected to test multiple parent devices and made some
assumptions based on reading the mdevctl code. These assumptions turned
out to be incorrect, so the parsing failed when devices from more than
one parent device were returned.

The details: mdevctl returns an array of objects representing the
defined devices. But instead of an array of multiple objects (with each
object representing a parent device), the array always contains only a
single object. That object has a separate property for each parent
device.

The sysfs content was also copied over from the VM but only those
files which are accessed in the test are stored in the repo.

5c359377a0 capabilities: Expose NUMA memory side cache
Memory on a NUMA node can have a side caches. Configuring these
for a domain was implemented in v6.6.0-rc1~249 and friends.
However, up until now mgmt applications did not really know what
values to pass because we were not exposing caches of the host.
With recent enough kernel these are exposed under sysfs and with
a bit of parsing we can extend our capabilities XML. The sysfs
structure is documented in kernel's
Documentation/admin-guide/mm/numaperf.rst and basically maps in
1:1 fashion to our virNumaCache structure.

5899bfd795 tests: glib-ify vircaps2xmltest
Ideally, turning pointers into g_auto* would be done in one step
and dropping cleanup label and unused @ret variable in second
step, but since this is a test we don't care that much, do we?
