When calling virConnectGetDomainCapabilities() (exposed as virsh
domcapabilities) users have option to specify whatever sub-set of
{ emulatorbin, arch, machine, virttype } they want. Then we have
a logic (hidden in virQEMUCapsCacheLookupDefault()) that picks
qemuCaps that satisfy values passed by user. And whatever was not
specified is then set to the default value as specified by picked
qemuCaps. For instance: if no machine type was provided but
emulatorbin was, then the machine type is set to the default one
as defined by the emulatorbin.
Or, when just virttype was set then the remaining three values
are set to their respective defaults. Except, we have a crasher
in this case:
# virsh domcapabilities --virttype hvf
error: Disconnected from qemu:///system due to end of file
error: failed to get emulator capabilities
error: End of file while reading data: Input/output error
This is because for 'hvf' virttype (at least my) QEMU does not
have any machine type. Therefore, @machine is set to NULL and the
rest of the code does not expect that.
What we can do about this is to validate all arguments. Well,
except for the emulatorbin which is obtained from passed
qemuCaps. This also fixes the issue when domcapabilities for a
virttype of a different driver are requested, or a different
arch.

When deciding whether to bind mount a path in domain's namespace,

"/dev/hugepages" already mounted inside the namespace and we are
deciding whether to bind mount "/dev/hugepages1G/..." we decide
to skip over the path and NOT bind mount it. This is because
plain STRPREFIX() is used and yes, the former is prefix of the

Our code relies on mount events propagating into the namespace we
create for a domain. However, there's one caveat. In v8.8.0-rc1~8
I've tried to make us detect differences in mount tables between
the namespace in which libvirtd runs and the domain namespace.
This is crucial for any mounts that happen after the domain was
started (for instance new hugetlbfs can be mounted on say
/dev/hugepages1G).
Therefore, we take a look into /proc/$(pgrep qemu)/mounts to see
what filesystems are mounted under /dev. Now, since we don't
umount the original /dev, just mount a tmpfs over it, we get all
the events (e.g. aforementioned hugetlbfs mount on
/dev/hugepages1G), but we are not really able to access it
because of the tmpfs that's placed on top. This then confuses our
algorithm for detecting which filesystems are mounted (the
algorithm is implemented in qemuDomainGetPreservedMounts()).
To break the link between host's and guest's /dev we just need to
umount() the original /dev in the namespace. Just before our
artificially created tmpfs is moved into its place.

Use of qemuDomainValidateVcpuInfo in the helpers for hotplug and unplug

The reason for this is that qemuDomainValidateVcpuInfo validates the
state of all vCPUs against the expected state of vCPUs. If an unplug
operation completed before libvirt was unable to process it yet the
expected state could not reflect the current state.
To avoid spurious errors the qemuDomainHotplugAddVcpu and
qemuDomainRemoveVcpu functions are modified to do localized validation
only for the vCPUs they actually modify.
We also now ensure that the cgroups are modified before bailing out on
error for any vCPUs which passed validation.
Additionally in order for qemuDomainRemoveVcpuAlias to be able to find
the unplugged vCPU we must ensure that qemuDomainRefreshVcpuInfo does
not clear out the alias in case when the vCPU is no longer reported by

destination side avoids setting seclabels on it to avoid cutting
off the source while it is still using it. Makes sense, except
for a wee bit: the secdriver API does a bit more - it also sets
label on the swtpm log file. And this one definitely needs to be
labeled (it lives under /var/log/swtpm/libvirt/qemu/..., i.e. not
on a shared volume).
Previously, qemuSecurityStartTPMEmulator() took care of that. But
during rework to shared volume migration, the code was changed so
now plain qemuSecurityCommandRun() would be run (i.e. no
relabelling).
But after previous commits, we can now chose whether the TPM

Inside of qemuTPMEmulatorBuildCommand() there are two calls to
qemuTPMSetupEncryption() which simply ignore returned error. This
is suboptimal because then we rely on swtpm binary reporting a
generic error (something among invalid command line arguments)
while an error reported by qemuTPMSetupEncryption() is more
specific.
However, since virCommandSetSendBuffer() only sets an error
inside of virCommand structure (the error is then reported in
virCommandRun()), we need to exempt its retval from error
checking. Thus, the signature of qemuTPMSetupEncryption() is
changed a bit so that -1/0 can be returned to indicate error.

When there is no vIOMMU, vfio devices don't need to lock the entire guest
memory per-device, but they still need to lock the entire guest memory to
share between all vfio devices. This memory accounting is not shared
with vDPA devices, so it should be added to the memlock limit separately.
Commit 8d5704e2 added support for multiple vfio/vdpa devices but
calculated the limits incorrectly when there were both vdpa and vfio
devices and no vIOMMU. In this case, the memory lock limit was not
increased separately for the vfio devices.

When post-copy migration is running in Finish phase we already did
everything needed and we're just waiting for all the memory to transfer
to the destination. The domain is already running on there at this
point. Once all data is transferred (QEMU sends a MIGRATION completed
event) we're done. So in this specific post-copy case the source does
not need to care about the result of the Finish call as long as QEMU
says migration completed. The Finish call to the destination daemon may
fail for reasons that do not affect QEMU, e.g., libvirt daemon was
restarted there or the libvirt connection broke.
Currently we just mark the post-copy migration as failed on the source
and keep the domain paused there. But when libvirt daemon is restarted
at this point, it will detect migration finished successfully and kill
the domain as migrated. It make sense to do this even without having to
restart the daemon.

The aim of thread-context object is to set affinity on threads
that allocate memory for a memory-backend-* object. For instance:
-object '{"qom-type":"thread-context","id":"tc-ram-node0","node-affinity":[3]}' \
-object '{"qom-type":"memory-backend-memfd","id":"ram-node0","hugetlb":true,\

"size":15032385536,"host-nodes":[3],"policy":"preferred",\
"prealloc-context":"tc-ram-node0"}' \
allocates 14GiB worth of memory, backed by 2MiB hugepages from
host NUMA node 3, using 8 threads. If it weren't for
thread-context these threads wouldn't have any affinity and thus
theoretically could be scheduled to run on CPUs of different NUMA
node (which is what I saw occasionally).
Therefore, whenever we are pinning memory (IOW setting host-nodes
attribute), we can generate thread-context object with the same
affinity.
