In my recent commit of a33279daa8 I've moved video model check
from domain capabilities validator into qemu validator. During
that I had to basically duplicate video model to qemuCaps checks.
Problem with this approach is that after my commit qemu validator
and domCaps are disconnected and thus domCaps might report (in
general) different set of supported video models.

The helper methods for getting integer properties ignore a missing

with the vendor and model IDs getting set to zero silently.
The few callers which relied on this silent defaulting have been fixed,

The access of DKD_MEDIA_AVAILABLE for floppy disks, is mistakenly

was only around for 3 Fedora releases before being killed off around
F13. Thus we can just remove this legacy property.

The udevProcessStorage method relies on udevGetIntProperty ignoring
errors about non-existant properties and instead setting the value to
zero. In theory when seeing ID_CDROM=1, you might expect that devices
which are not CDs will get ID_CDROM=0, but that's not what happens in
practice. Instead the property simply won't get set at all.
IOW, the code does not need to care about the value of the property,
merely whether it exists or not.

'kvm-spice' is a binary name used to call 'kvm' which actually is a wrapper
around qemu-system-x86_64 enabling kvm acceleration. This isn't in use
for quite a while anymore, but required to work for compatibility e.g.
when migrating in old guests.
For years this was a symlink kvm-spice->kvm and therefore covered
apparmor-wise by the existing entry:
/usr/bin/kvm rmix,
But due to a recent change [1] in qemu packaging this now is no symlink,
but a wrapper on its own and therefore needs an own entry that allows it
to be executed.

In v6.3.0-rc1~67 I've made a switch: instead of listening on udev
events the nodedev driver started listening for kernel events.
This was because when a device changes its name (e.g. NICs) we
will get "move" event with DEVPATH_OLD property set, which we can
then use to remove the old device and thus keep our internal list
up to date. The switch to "kernel" source was made because if the
old NICs naming (eth0, eth1, ...) is enabled (e.g. via
net.ifnames=0 on the kernel cmd line) then udev overwrites the
property with the new name making our internal list go out of
sync. Interestingly, when the od NICs naming is not enabled then
the DEVPATH_OLD contains the correct value.
But as it turns out, "kernel" source might be missing some other
important properties, e.g. USB vendor/product IDs. Therefore,
switch back to "udev" source and wish the best of luck to users
using the old NICs naming.

Currently, whenever a domain capabilities is needed (fortunately,
after cleanup done by previous commits it is now only in
virConnectGetDomainCapabilities()), the object is stored in a
cache. But there is no invalidation mechanism for the cache
(except the implicit one - the cache is part of qemuCaps and thus
share its lifetime, but that is not enough). Therefore, if
something changes - for instance new firmware files are
installed, or old are removed these changes are not reflected in
the virConnectGetDomainCapabilities() output.
Originally, the caching was there because domCaps were used
during device XML validation and they were used a lot from our
test suite. But this is no longer the case. And therefore, we
don't need the cache and can construct fresh domCaps on each
virConnectGetDomainCapabilities() call.

Libvirt's backup code has two modes:
1) push - where qemu actively writes the difference since the checkpoint
into the output file
2) pull - where we instruct qemu to expose a frozen disk state along
with a bitmap of blocks which changed since the checkpoint
For push mode qemu needs the temporary bitmap we use where we calculate
the actual changes to be present on the block node backing the disk.
For pull mode where we expose the bitmap via NBD qemu actually wants the
bitmap to be present for the exported block node which is the scratch
file.
Until now we've calculated the bitmap twice and installed it both to the
scratch file and to the disk node, but we don't need to since we know
when it's needed.
Pass in the 'pull' flag and decide where to install the bitmap according
to it and also when to register the bitmap name with the blockjob.

While it's certainly good to log events like "failed to close fd"

consequence of some bug in libvirt, logging a message every single
time a file descriptor is closed successfully is perhaps excessive
and can lead to useful information being missed among the noise.
Log filters don't help in this situation, because filtering out all

to be left out as well.
To give an idea of just how much noise this single debug statement
can cause, here's a real life example from a quite large libvirtd

Before commit 24d8968c, virDirClose took a DIR**, and that was never
NULL, so its declaration included ATTRIBUTE_NONNULL(1). Since that
commit, virDirClose takes a DIR*, and it may be NULL (e.g. if the DIR*
is initialized to NULL and was never closed).
Even though virDirClose() is currently only called implicitly (as the
cleanup for a g_autoptr(DIR)), and (as I've just newly learned) the
autocleanup function g_autoptr will only be called if the pointer in
question is non-null (see the definition of
_GLIB_AUTOPTR_CLEAR_FUNC_NAME in
/usr/include/glib-2.0/glib/gmacros.h), it does still cause Coverity to
complain that it *could* be called with a NULL, and it's also possible
that in the future someone might add code that explicitly calls
virDirClose.
To eliminate the Coverity complaints, and protect against the
hypothetical future where someone both explicitly calls virDirClose()
with a potentially NULL value, *and* re-enables the nonnull directive
when not building with Coverity (disabled by commit eefb881) this
patch removes the ATTRIBUTE_NONNULL(1) from the declaration of
virDirClose().

The remember owner feature uses XATTRs to store original
seclabels. But that means we don't want a regular user to be able
to change what we stored and thus trick us into setting different
seclabel. Therefore, we use namespaces that are reserved to
CAP_SYS_ADMIN only. Such namespaces exist on Linux and FreeBSD.
That also means, that the whole feature is enabled only for
qemu:///system. Now, while the secdriver code is capable of
dealing with XATTRs being unsupported (it has to, not all
filesystems support them) if the feature is enabled users will
get an harmless error message in the logs and the feature
disables itself.
Since we have virSecurityXATTRNamespaceDefined() we can use it to
make a wiser decision on the default state of the feature.

And what qemusecuritytest does is it checks whether we have not
