libvirt 8.6.0 introduced these checks and very clearly delineated
two possible firmware selection scenarios: manual firmware
selection, where the user is responsible for providing all
information, and firmware autoselection, where a list of desired
features is provided and everything else is handled by libvirt.
In the interest of maintaining the clear separation between these
two scenarios, setting most attributes when firmware autoselection
is active will result in the configuration being rejected.
This works fine, but is unnecessarily restrictive: in most cases,
the additional information that the user has provided matches
the information that libvirt would have discovered on its own by
looking at firmware descriptors, and asking the user to scrub it
from the XML only result in pointless friction.
Remove these checks entirely.
Unsurprisingly, this results in a few test cases that were
rejected until now to suddenly start working and producing
sensible results.
The firmware-auto-efi-loader-path-nonstandard test case is
notable: while we can now enable the xml2xml part of the test,
the xml2argv part is still failing, although in a slightly
different way. This is expected: since the firmware binary is a
non-standard one, libvirt is unable to figure out the missing
information from a firmware descriptor, and the configuration
is still ultimately an invalid one. However, if we were to find
such a configuration on disk at daemon startup, we would not
ignore it completely and instead would offer the user a chance
to fix it.

When a thread-context object is specified on the cmd line, then
QEMU spawns a thread and sets its affinity to the list of NUMA
nodes specified in .node-affinity attribute. And this works just
fine, until the main QEMU thread itself is not restricted.
Because of v5.3.0-rc1~18 we restrict the main emulator thread
even before QEMU is executed and thus then it tries to set
affinity of a thread-context thread, it inevitably fails with:
Setting CPU affinity failed: Invalid argument
Now, we could lift the pinning temporarily, let QEMU spawn all
thread-context threads, and enforce pinning again, but that would
require some form of communication with QEMU (maybe -preconfig?).
But that would still be wrong, because it would circumvent
<emulatorpin/>.
Technically speaking, thread-context is an internal
implementation detail of QEMU, and if it weren't for it, the main
emulator thread would be doing the allocation. Therefore, we
should honor the pinning and prune the list of node so that
inaccessible ones are dropped.

We have this crazy backwards compatibility when it comes to
serial and console devices. Basically, in same cases the very
first <console/> is just an alias to the very first <serial/>
device. This is to be seen at various places:
1) virDomainDefFormatInternalSetRootName() - when generating
domain XML, the <console/> configuration is basically ignored
and corresponding <serial/> config is formatted,
2) virDomainDefAddConsoleCompat() - which adds a copy of
<serial/> or <console/> into virDomainDef in post parse.
And when talking to QEMU we need a special handling too, because
while <serial/> is generated on the cmd line, the <console/> is
not. And in a lot of place we get it right. Except for generating
device aliases. On domain startup the 'expected' happens and
devices get "serial0" and "console0" aliases, correspondingly.
This ends up in the status XML too. But due to aforementioned
trick when formatting domain XML, "serial0" ends up in both
'virsh dumpxml' and the status XML. But internally, both devices
have different alias. Therefore, detaching the device using
<console/> fails as qemuDomainDetachDeviceChr() tries to detach
"console0".
After the daemon is restarted and status XML is parsed, then
everything works suddenly. This is because in the status XML both
devices have the same alias.
Let's generate correct alias from the beginning.

will be unexpectedly left paused when the API finishes. This situation
is reported via VIR_DOMAIN_EVENT_SUSPENDED event with
VIR_DOMAIN_EVENT_SUSPENDED_API_ERROR detail. But we do not have a
corresponding reason for VIR_DOMAIN_PAUSED state and the reason would
remain set to the value used when the domain was paused. So the state
reason would suggest the operation is still running.
This patch changes the state reason to a new VIR_DOMAIN_PAUSED_API_ERROR

For some vhostuser daemons, we validate that the guest memory is shared
with the host.
With earlier versions of QEMU, it was only possible to mark memory
as shared by defining an explicit NUMA topology. Later, QEMU exposed
the name of the default memory backend (defaultRAMid) so we can mark
that memory as shared.
Since libvirt commit:
commit bff2ad5d6b1f25da02802273934d2a519159fec7
qemu: Relax validation for mem->access if guest has no NUMA
we already check for the case when user requests shared memory,
but QEMU did not expose defaultRAMid.
Drop the duplicit check from vhostuser device validation, to make
it pass on hotplug even after libvirtd restart.
This avoids the need to store the defaultRAMid, since we don't really
need it for anything after the VM has been already started.
