In order to learn what types of <launchSecurity/> are supported
users can turn to domain capabilities and find <sev/> and

on individual launchSecurity types, we are lacking clean
enumeration (like we do for say device models). And given that
SEV and SEV SNP share the same basis (info found under <sev/> is

While it's very unlikely to have QEMU that supports SEV-SNP but
doesn't support plain SEV, for completeness sake we ought to
query SEV capabilities if QEMU supports either. And similarly to
QEMU_CAPS_SEV_GUEST we need to clear the capability if talking to
QEMU proves SEV is not really supported.
This in turn removes the 'sev-snp-guest' capability from one of
our test cases as Peter's machine he uses to refresh capabilities
is not SEV capable. But that's okay. It's consistent with

Add plumbing for QEMU's switchover-ack migration capability, which
helps lower the downtime during VFIO migrations. This capability is
enabled by default as long as both the source and destination support
it.
Note: switchover-ack depends on the return path capability, so this may
not be used when VIR_MIGRATE_TUNNELLED flag is set.
Extensive details about the qemu switchover-ack implementation are
available in the qemu series v6 cover letter [1] where the highlight is
the extreme reduction in guest visible downtime. In addition to the
original test results below, I saw a roughly ~20% reduction in downtime
for VFIO VGPU devices at minimum.
=== Test results ===
The below table shows the downtime of two identical migrations. In the
first migration swithcover ack is disabled and in the second it is
enabled. The migrated VM is assigned with a mlx5 VFIO device which has
300MB of device data to be migrated.
+----------------------+-----------------------+----------+
| Switchover ack | VFIO device data size | Downtime |
+----------------------+-----------------------+----------+
| Disabled | 300MB | 1900ms |
| Enabled | 300MB | 420ms |
+----------------------+-----------------------+----------+
Switchover ack gives a roughly 4.5 times improvement in downtime.
The 1480ms difference is time that is used for resource allocation for
the VFIO device in the destination. Without switchover ack, this time is
spent when the source VM is stopped and thus the downtime is much
higher. With switchover ack, the time is spent when the source VM is
still running.

When starting a domain on a host which lacks a vmx-* CPU feature which
is expected to be enabled by the CPU model specified in the domain XML,
libvirt properly marks such feature as disabled in the active domain
XML. But migrating the domain to a similar host which lacks the same
vmx-* feature will fail with libvirt reporting the feature as missing.
This is because of a bug in the hack ensuring backward compatibility
libvirt running on the destination thinks the missing feature is

When the chain names and table name used by the nftables firewall

958aa7f274, I forgot to change the test
data file base.nftables, which has the extra "list" and "add
chain/table" commands that are generated for the first test case of
networkxml2firewalltest.c. When the full set of tests is run, the
first test will be an iptables test case, so those extra commands
won't be added to any of the nftables cases, and so the data in
base.nftables never matches, and the tests are all successful.
However, if the test are limited with, e.g. VIR_TEST_RANGE=2 (test #2
will be the nftables version of the 1st test case), then the commands
to add nftables table/chains *will* be generated in the test output,
and so the test will fail. Because I was only running the entire test
series after the initial commits of nftables tests, I didn't notice
this. Until now.
base.nftables has now been updated to reflect the current names for
chains/table, and running individual test cases is once again
successful.

A user reported that if they set <forward mode='nat|route' dev='blah'>
starting the network would fail if the device 'blah' didn't already
exist.
This is caused by using "iif" and "oif" in nftables rules to check for
the forwarding device - these two commands work by saving the named
interface's ifindex (an unsigned integer) when the rule is added, and
comparing it to the ifindex associated with the packet's path at
runtime. This works great if the interface both 1) exists when the
rule is added, and 2) is never deleted and re-created after the rule
is added (since it would end up with a different ifindex).
When checking for the network's bridge device, it is okay for us to
use "iif" and "oif", because the bridge device is created before the
firewall rules are added, and will continue to exist until just after
the firewall rules are deleted when the network is shutdown.
But since the forward device might be deleted/re-added during the
lifetime of the network's firewall rules, we must instead us "oifname"
and "iifname" - these are much less efficient than "Xif" because they
do a string compare of the interface's name rather than just comparing
two integers (ifindex), but they don't require the interface to exist
when the rule is added, and they can properly cope with the named
interface being deleted and re-added later.

'qemuDomainObjStopWorker()' which is meant to dispose of the event loop
thread for the monitor unlocks the VM object while disposing the thread
to prevent possible deadlocks with events waiting on the monitor thread.
Unfortunately 'qemuDomainObjStopWorker()' is called *before* the VM is
marked as inactive by clearing 'vm->def->id', but at the same time it's
no longer marked as 'beingDestroyed' when we're inside
'qemuProcessStop()'.
If 'vm' would be kept locked this wouldn't be a problem. Same way it's
not a problem for anything that uses non-ASYNC VM jobs, or when the
monitor is accessed in an async job, as the 'destroy' job interlocks
with those.
It is a problem for code inside an async job which uses
'qemuDomainObjWait()' though. The API contract of qemuDomainObjWait()
ensures the caller that the VM on successful return from it, but in this
specific reason it's not the case, as both 'beingDestroyed' is already
false, and 'vm->def->id' is not yet cleared.
To fix the issue move the 'qemuDomainObjStopWorker()' call *after*
clearing 'vm->def->id' and also add a note stating what the function is
doing.
