I have just tagged v9.2.0-rc2 in the repository and pushed signed
tarballs and source RPMs to https://libvirt.org/sources/
Please give the release candidate some testing and in case you find a
serious issue which should have a fix in the upcoming release, feel
free to reply to this thread to make sure the issue is more visible.
If you have not done so yet, please update NEWS.rst to document any
significant change you made since the last release.
Thanks,
Jirka

The 9.1.0 release of both libvirt and libvirt-python is tagged and
signed tarballs and source RPMs are available at
https://libvirt.org/sources/https://libvirt.org/sources/python/
Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing feedback. Your work is greatly
appreciated.
* Removed features
* vbox: removed support for version 5.2 and 6.0 APIs
Libvirt no longer supports use of VirtualBox 5.2 and 6.0 since these
versions reached their end of life on 2020/07.
* New features
* vbox: added support for version 7.0 API
Libvirt can now support use of the VirtualBox 7.0, This is compile tested
only, so we are looking for feedback from users on how well it works in
practice.
* qemu: Support crypto device
Support crypto device(virtio crypto only), also add support for QEMU with
backend ``builtin`` and ``lkcf``.
* qemu: added support for pvpanic-pci device
A pvpanic device can be now defined as a PCI device (the original is an ISA
device) with ``<panic model='pvpanic'/>``.
* qemu: support automatic restart of inadvertently terminated passt process
If the passt process that is serving as the backend of a -netdev
stream is terminated unexpectedly, libvirt now listens to QEMU's
notification of this, and starts up a new passt instance, thus
preserving network connectivity.
* Improvements
* RPM packaging changes
The ``libvirt-daemon`` subpackage is split into several new subpackages,
allowing installation of a modular daemon configuration without the
traditional monolithic libvirtd.
* Bug fixes
* QEMU: iTCO watchdog made operational
The watchdog was always included when q35 machine type was used, but needed
an extra bit of configuration in order to be operational. This is now done
by default when running a QEMU domain with q35 machine type. This is not a
change in the guest ABI, but it is a guest visible behavior change since the
watchdog that did not fire before will now fire once used. To switch to the
previous behavior the watchdog action must be set to ``none``.
* QEMU: fix deleting memory snapshot when deleting external snapshots
When external snapshot deletion was introduced it did not remove memory
snapshot when it existed. In addition when external memory only snapshot
was created libvirt failed without producing any error.
* QEMU: properly report passt startup errors
Due to how the child passt process was started, the initial
support for passt (added in 9.0.0) would not see errors
encountered during startup, so libvirt would continue to setup and
start the guest; this led to a running guest with no network
connectivity.
(NB: On systems that use them, it is still necessary to disable
SELinux/AppArmor to start passt. This is a temporary limitation,
and use of the feature in production is strongly discouraged
until it has been lifted.)
* qemu: Fix error when attempting to change media in a CDROM drive
Due to a logic bug introduced in libvirt-9.0 attempts to change media in a
CDROM would previously fail with an error stating that the tray isn't open.
* qemu: Properly handle block job transitions
Starting with libvirt-9.0 the block job state machine improperly handled
some job transitions, which resulted into some block jobs not being
properly terminated. This could cause problems such as errors when
detaching a disk after snapshot.
* virsh: Make domif-setlink work more than once
There was a bug introduced in the previous release which made ``virsh
domif-setlink`` work exactly once over given domain. The bug was fixed and
now the command can be run multiple times.
* qemu: Make domain startup fail if NIC already exists
When starting a domain with an ``<interface/>`` that's supposed to be
managed by libvirt (``managed='yes'``) but corresponding TAP device already
exists, report an error and make the startup process fail.
* qemu: Deal with nested mounts when umount()-ing /dev
When setting up private ``/dev`` for a domain (also known as ``namespaces``
in ``qemu.conf``), libvirt preserves mount points nested under ``/dev``
(e.g. ``/dev/shm``, ``/dev/pts`` and so on). But there was a bug which
resulted in inability to construct the namespace when there were two or
more filesystems mounted on the same path. This is common scenario with
containers and thus the bug was fixed.
* remote: Pass ``mode`` and ``socket`` URI parameters to virt-ssh-helper
When connecting to a remote host using SSH transport, ``?mode=`` and
``?socket=`` URI parameters were ignored. This prevented users from
connecting to a monolithic daemon running on a remote host.
* qemu: Various ``swtpm`` related fixes
There are more cleanups and small bug fixes with regards to emulated
``<tpm/>``. For instance with migration when the ``swtpm`` state is on a
shared volume, or seclabel setting/restoring.
Enjoy.
Jirka
