Release of libvirt-9.2.0
The 9.2.0 release of both libvirt and libvirt-python is tagged and
signed tarballs and source RPMs are available at
https://libvirt.org/sources/

Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing feedback. Your work is greatly
appreciated.
* New features
* qemu: Add support for QCOW2 formatted firmware
This type of firmware can be picked up either automatically, if the
corresponding JSON descriptor has the highest priority, or manually by
using ``<loader format='qcow2'/>`` in the domain XML.
* Improvements
* qemu: Make firmware selection persistent
Up until now, firmware autoselection has been performed at domain startup
time: as a result, changes to the JSON firmware descriptors present on the
system could have translated to a different firmware being chosen for
subsequent startups of the same domain, potentially rendering it unbootable
or lowering the security guarantees. Firmware selection now happens once,
when the domain is defined, and its results are stored in the domain XML
to be reused, unchanged, for all subsequent boots.
* qemu: passt now works when SELinux/AppArmor is enabled
In the case of SELinux, this requires passt-specific support code to be
present in the host policy, so it might only work with upcoming operating
systems and not with existing ones.
* xen: Support custom UEFI firmware paths
The Xen libxl driver now supports specifying a custom UEFI firmware path.
Previously the Xen default was used in all cases.
* Bug fixes
* qemu: Fix validation of the HPET timer
Due to a logic bug introduced in libvirt 9.0.0, VM configurations
explicitly enabling the HPET timer were rejected.
* qemu: Fix thread-context .host-nodes generation
With new enough QEMU, libvirt instructs QEMU to set affinity of memory
allocation threads. But this may have resulted in QEMU being unable to do
so, as affinity to NUMA nodes inaccessible to emulator thread might have
been requested.
* rpc: fix typo in admin code generation
Fix the bug in the remote ``virt-admin`` code generator, that resulted
in a crash. Introduced in libvirt 9.1.0.
* qemu: relax shared memory check for vhostuser daemons
Fix hotplug of virtiofs ``filesystem`` after restarting libvirtd.
Before, libvirtd would incorrectly complain about missing shared
memory.
Enjoy.
