The mpx feature was removed from the corresponding qemu cpu models.
With mpx in the libvirt cpu models, libvirt believes the feature
to be implicitly enabled when creating qemu VMs, while in fact it is
disabled.
This became an issue when commit 94eacd5a5f introduced new vmx-*
features, of which some are dependent on mpx (see "feature_dependencies"
table in qemu target/i386/cpu.c), e.g. vmx-exit-clear-bndcfgs and
vmx-entry-load-bndcfgs. These features cannot be enabled by qemu
without also mpx being enabled, leading to the error message
error: Failed to create domain from testdomain.xml
error: operation failed: guest CPU doesn't match

does support mpx and the mentioned vmx-* features:

Features removed from a CPU model are marked with "removed='yes'"
attribute in the CPU map. Such features will always be present in a CPU
definition produced by libvirt regardless on their state. In other words
a running domain (even saved in a file) will always explicitly contain
states of all features removed from the specified CPU model. This
enables migration to older libvirt which would otherwise think the
affected features should be enabled as they are still included in the
CPU model in the older version of CPU map. Migration from an old libvirt
to a new one would be broken as the new libvirt would think the removed
features should be disabled (because they are not included in the CPU
model anymore), which might not be the case on the source host. Thus we
were refusing to remove CPU features unless they were never working and
no domain could even be running with those features enabled.
This patch removes the limitation. When handling CPU definitions with
missing features marked as removed in the specified CPU model, we know
whether it comes from a running domain, in which case it must have been
created by older libvirt where the missing CPU features were not removed
yet. This means the features must have been enabled on the source and we
can automatically fix the definition by adding the missing features with
correct states.
We can safely remove any CPU feature from our CPU models now, but it
should only be used for features removed from all versions of a given
CPU model in QEMU because unversioned models correspond to v1.

Instead of parsing the vspc URL with something along the lines of

The root cause is a bad assumption in the virNetClientIOEventLoop
method. This method is run by whichever thread currently owns the
buck, and is responsible for handling I/O. Inside a for(;;) loop,
this method creates a temporary GSource, adds it to the event loop
and runs g_main_loop_run(). When I/O is ready, the GSource callback
(virNetClientIOEventFD) will fire and call g_main_loop_quit(), and
return G_SOURCE_REMOVE which results in the temporary GSource being
destroyed. A g_autoptr() will then remove the last reference.
What was overlooked, is that a second thread can come along and
while it can't enter virNetClientIOEventLoop, it will register an
idle source that uses virNetClientIOWakeup to interrupt the
original thread's 'g_main_loop_run' call. When this happens the
virNetClientIOEventFD callback never runs, and so the temporary
GSource is not destroyed. The g_autoptr() will remove a reference,
but by virtue of still being attached to the event context, there
is an extra reference held causing GSource to be leaked. The
next time 'g_main_loop_run' is called, the original GSource will
trigger its callback, and access data that was allocated on the
stack by the previous thread, and likely SEGV.
To solve this, the thread calling 'g_main_loop_run' must call
g_source_destroy, immediately upon return, to guarantee that
the temporary GSource is removed.

While QEMU accepts and interprets an empty string in the tls-hostname
field in migration parametes as if it's unset, the same does not apply
for the 'tls-hostname' field when 'blockdev-add'-ing a NBD backend for
non-shared storage migration.
When libvirt sets up migation with TLS in 'qemuMigrationParamsEnableTLS'
the QEMU_MIGRATION_PARAM_TLS_HOSTNAME migration parameter will be set to
empty string in case when the 'hostname' argument is passed as NULL.
Later on when setting up the NBD connections for non-shared storage
migration 'qemuMigrationParamsGetTLSHostname', which fetches the value
of the aforementioned TLS parameter.
This bug was mostly latent until recently as libvirt used
MIGRATION_DEST_CONNECT_HOST mode in most cases which required the
hostname to be passed, thus the parameter was set properly.
This changed with 8d693d79c4 for post-copy migration, where libvirt now
instructs qemu to connect and thus passes NULL hostname to
qemuMigrationParamsEnableTLS, which in turn causes libvirt to try to
add NBD connection with empty string as tls-hostname resulting in:
error: internal error: unable to execute QEMU command 'blockdev-add': Certificate does not match the hostname
To address this modify 'qemuMigrationParamsGetTLSHostname' to undo the
weird semantics the migration code uses to handle TLS hostname and make
it return NULL if the hostname is an empty string.

Since OVS keeps desired state in a DB, upon sudden crash of the

shutdown or NIC hotunplug as we call corresponding del-port
function (virNetDevOpenvswitchRemovePort()). But if the host
suddenly crashes we won't ever do that. What happens next, is
when OVS starts it finds desired state in its DB and creates a
stale port.
OVS added support for transient ports in v2.5.0 (Feb 2016) and
since its v2.9.0 it even installs a systemd service
(ovs-delete-transient-ports) that automatically deletes transient
ports on system startup. If we mark a port as transient then OVS
won't restore its state on restart after crash.
This change may render "--may-exist" argument redundant, but I'm
not sure about all the implications if it was removed. Let's keep

For cold plugged devices this is not a problem, because firmware
sets PCI controllers in a way that make devices behind them just
work. Problem arises if such PCI device is to be hot plugged.
Since the PCI device wasn't present at cold boot, firmware could
not take it into calculations and the amount of reserved memory

This patch will allow usb-net devices to be automatically assigned a USB
address (and skip any attempt to assign a PCI one).

Commit 2ecdf25929 was intended to
implement two things: reduce stack usage inside ACL helpers and
minimally initialize virDomainDef object to avoid passing garbage
inside validation framework. Though original commit has not
touched other ACL helpers.
This patch adds proper clauses to
remoteRelayNetworkEventCheckACL
remoteRelayStoragePoolEventCheckACL
remoteRelayNodeDeviceEventCheckACL
remoteRelaySecretEventCheckACL

Add DMI support for risc-v and mips. Attempt to read dmidecode and
fall back to old behavior if that fails.
The SMBIOS specification[1] officially supports both RISC-V and LoongArch.
Some mips-based Loongson-3 processors also have SMBIOS.

Implement display="on" and ramfb="on" for vfio PCI host devices in qemu.
This enables passthrough PCI devices for display just like we did for
mdevs.

We already allow the user to specify display="on" and ramfb="on" for
mdev host devices. But newer GPU models will no longer use the mdev
framework, so we should enable this same functionality for other
non-mdev passthrough PCI devices.

The test simply invokes libvirtd and expects it to fail. We can do that
directly in meson without the need for a wrapper script.
