When cleaning up after removed device, qemuDomainChrRemove() is
called. But this may fail, in which case we successfully ignore
the failure and virDomainChrDefFree() the device anyway. While it
decreases our memory consumption, it's a bit too far, especially
if the next step is 'virsh dumpxml'. Then our memory consumption
decreases all the way down to zero as we crash.

When hotpluging a <serial/> device, we might need to add a

Now, hotplugging is done in several phases. In one of them,
qemuDomainChrPreInsert() allocates space for both devices, and
then qemuDomainChrInsertPreAlloced() actually inserts the device
into domain definition and sets up the <console/> device with it.
Except, the condition that checks whether to create the aliased
<console/> is wrong as it compares nconsoles against 0.
Surprisingly, qemuDomainChrInsertPreAllocCleanup() doesn't suffer
from the same error.

Historically the snapshot code attempted to forbid internal snapshots

which made users rely on the feature.
Now with the changes to store detected UEFI environment also in the
inactive definition this broke the feature for those users.
Since the varstore doesn't really change that much in the lifecycle of a
VM it usually is okay to simply leave it as is.
Restore the functionality for inactive snapshots by disabling the check.

where and additional callback can be passed. This callback is
then called with _virConnectCredential struct filled partially
and it's callback's responsibility to get desired data (e.g. by
prompting user) and store it into .result member of the struct.
But we document the callback behaviour as:
When authentication requires one or more interactions, this callback
is invoked. For each interaction supplied, data must be gathered
from the user and filled in to the 'result' and 'resultlen' fields.
If an interaction cannot be filled, fill in NULL and 0.
Returns 0 if all interactions were filled, or -1 upon error
But there are some buggy callbacks out there, which set:
.result = NULL;
.resultlen = 0;

Similarly, even when the user is not guiding the autoselection
process by specifying the desired status of certain features
and instead is relying on the system-level descriptor priority
being set up correctly, libvirt will still ultimately decide to
use a specific descriptor, which includes information about the
firmware's features.
In both these cases, take the additional information that were

this information and explicit firmware details, as long of
course as everything is internally consistent, and that we've
ensured that we produce maximally compatible XML on migration,
we can stop stripping this information at the end of the
firmware selection process.
There are several advantages to keeping this information around:
* if the user wants to change the firmware configuration for
an existing VM, they can simply drop the <loader> and
<nvram> elements, tweak the firmware autoselection parameters
and let libvirt pick a firmware that matches on the new
requirements;
* management applications can inspect the XML and easily
figure out firmware-related information without having to
reverse-engineer them based on some opaque paths.
Overall, this change makes things more transparent and easier to

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.

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 bff2ad5d6b
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.

Normally when a child process is started by libvirt, the SELinux label
of that process is set to virtd_t (plus an MCS range). In at least one
case (passt) we need for the SELinux label of a child process label to
match the label that the binary would have transitioned to
automatically if it had been run standalone (in the case of passt,
that label is passt_t).
This patch modifies virSecuritySELinuxSetChildProcessLabel() (and all
the functions above it in the call chain) so that the toplevel
function can set a new argument "useBinarySpecificLabel" to true. If
it is true, then virSecuritySELinuxSetChildProcessLabel() will call
the new function virSecuritySELinuxContextSetFromFile(), which uses
the selinux library function security_compute_create() to determine
what would be the label of the new process if it had been run
standalone (rather than being run by libvirt) - the MCS range from the
normally-used label is added to this newly derived label, and that is
what is used for the new process rather than whatever is in the
domain's security label (which will usually be virtd_t).
In order to easily verify that nothing was broken by these changes to
the call chain, all callers currently set useBinarySpecificPath =
false, so all behavior should be completely unchanged. (The next
patch will set it to true only for the case of running passt.)

VIR_DOMAIN_NET_TYPE_NULL and VIR_DOMAIN_NET_TYPE_VDS are not implemented
for the qemu driver but the formatter code in 'qemuBuildHostNetProps'
didn't report an error for them and didn't even return from the function
when they were encountered.
This caused a crash in 'virJSONValueObjectAppendStringPrintf' which
does not tolerate NULL JSON object to append to when the unsupported
devices were used.
Properly report error when unhandled devices are encountered. This also
includes the case for VIR_DOMAIN_NET_TYPE_HOSTDEV, but that code path
should never be reached.

QEMU deprecated the '-no-acpi' option, thus we should switch to the
modern way to use '-machine'.
Certain ARM machine types don't support ACPI. Given our historically
broken design of using '<acpi/>' without attribute to enable ACPI and
qemu's default of enabling it without '-no-acpi' such configurations
would not work.
Now when qemu reports whether given machine type supports ACPI we can do
a better decision and un-break those configs. Unfortunately not
retroactively.

For unmanaged ethernet <interface/>, it is user's responsibility
to set up the interface. And as such it can be just anything.
Therefore, it's (almost) impossible for the

When fetching stats for a domain's <interface/>, or when setting
up its QoS, we can face two situations:
1) the device "shares" the host view, meaning each packet
sent/received on the interface by a domain is accounted for in
the same category on the host, or
2) the device is at the other side, and a packet send by a
domain, is in fact packet received on the host.
This fact affects whether we need to swap RX/TX values when
fetching stats, or setting up QoS. We have this convenient helper
function (virDomainNetTypeSharesHostView()), which returns to
which category given interface type falls into.
Now, for unmanaged type='ethernet' our options are quite limited,
because it's user's responsibility to set up the host side of the
interface. And it can be just anything. Fortunately, we have
another convenience function (virNetDevMacVLanIsMacvtap()), which
determines whether given interface is a macvtap (which is
notoriously known for falling into the first category).
Let's use it to help virDomainNetTypeSharesHostView() determine
the view more accurately.

Currently, firmware selection is performed as part of the
domain startup process. This mostly works fine, but there's a
significant downside to this approach: since the process is
affected by factors outside of libvirt's control, specifically
the contents of the various JSON firmware descriptors and
their names, it's pretty much impossible to guarantee that the
outcome is always going to be the same. It would only take an
edk2 update, or a change made by the local admin, to render a
domain unbootable or downgrade its boot security.
To avoid this, move firmware selection to the postparse phase.
This way it will only be performed once, when the domain is
first defined; subsequent boots will not need to go through
the process again, as all the paths that were picked during
firmware selection are recorded in the domain XML.
Care is taken to ensure that existing domains are handled
correctly, even if their firmware configuration can't be
successfully resolved. Failure to complete the firmware
selection process is only considered fatal when defining a
new domain; in all other cases the error will be reported
during startup, as is already the case today.
