Entering freeze for libvirt-7.3.0
by Jiri Denemark
I have just tagged v7.3.0-rc1 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,

Release of libvirt-7.2.0
by Jiri Denemark
The 7.2.0 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 any other feedback. Your work is
greatly appreciated.
* New features
* qemu: Implement domain memory dirty rate calculation API
New API ``virDomainStartDirtyRateCalc()`` and virsh command
``domdirtyrate-calc`` are added to start calculating a live domain's
memory dirty rate.
* qemu: Support reporting memory dirty rate stats
The memory dirty rate stats can be obtained through ``virsh domstats
--dirtyrate`` via the virConnectGetAllDomainStats API.
* qemu: Full disk backups via ``virDomainBackupBegin``
The qemu hypervisor driver now allows taking full disk backups via the
``virDomainBackupBegin`` API and the corresponding virsh wrapper.
In future releases the feature will be extended to also support incremental
backups (where only the difference since the last backup is copied) when
qemu adds the required functionality.
* Add support for audio backend specific settings
With this release a new ``<audio/>`` element is introduced that allows
users to configure audio output for their guests.
* Improvements
* qemu: Compatibility with QEMU 6.0 for certain hot-(un)-plug operations
Libvirt 7.2.0 is required for compatibility with the upcoming QEMU 6.0
release for hotplug and hotunplug of certain devices and helpers, such as
iothreads, chardevs, RNG devices, disks with secret, ...
* qemu: Various improvements to embedded mode
Embedded mode for the QEMU driver, as well as the ``virt-qemu-run`` tool
saw improvements in handling of domain life cycle, temporary directories
creation (important when using disk secrets) and other minor fixes.
* Documentation of split daemon related config files
Split daemons read configuration files upon their start. These were never
documented though.
* Bug fixes
* Check host CPU for forbidden features
CPU feature policy did not work as expected with ``host-passthrough`` and
features supported by physical host. CPU features were not filtered out
when ``@check`` was set to ``full``.
* Fix virNetworkUpdate() to work with split daemons
Due to a bug in our code, virNetworkUpdate() did not work with split daemon
unless management application connected to virtnetworkd directly.
* qemu: increase locked memory limit when a vDPA device is present
Just like VFIO devices, vDPA devices may need to have all guest memory
pages locked/pinned in order to operate properly. These devices are now
included when calculating the limit for memory lock.
* Don't log error if SRIOV PF has no associated netdev
Some SRIOV PFs don't have a netdev associated with them in which case
libvirtd reported an error and refused to start. This is now fixed.
* qemu: Only raise memlock limit if necessary
Attempting to set the memlock limit might fail if we're running
in a containerized environment where ``CAP_SYS_RESOURCE`` is not
available, and if the limit is already high enough there's no
point in trying to raise it anyway.
* Restore security context of swtpm.log
If a guest with emulated TPM was started and the daemon was restarted
afterwards, the security context of the per-domain ``swtpm.log`` file was
not restored on domain shutdown leaving it unable to be started again.
* virtlogd|virtlockd: Fixed crash when upgrading the daemons in-place
A bug preventing the in-place upgrade of ``virtlogd`` and ``virtlockd``
daemons was fixed, so they can again be upgraded without dropping the log
file descriptors or locks on files.
Enjoy.
