Entering freeze for libvirt-9.6.0
by Jiri Denemark
I have just tagged v9.6.0-rc1 in the repository and pushed signed
tarballs and source RPMs to https://download.libvirt.org/
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-9.5.0
by Jiri Denemark
The 9.5.0 release of both libvirt and libvirt-python is tagged and
signed tarballs and source RPMs are available at
https://download.libvirt.org/
https://download.libvirt.org/python/
Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing feedback. Your work is greatly
appreciated.
* New features
* qemu: Allow configuring the ``discard-no-unref`` feature of ``qcow2`` driver
The new ``discard_no_unref`` attribute of the ``disk`` ``driver`` element
controls whether the ``qcow2`` driver in qemu unrefs clusters inside the
image on discard requests. Disabling cluster unrefing decreases fragmentation
of the image.
* Improvements
* qemu: Include maximum physical address size in baseline CPU
When computing a baseline CPU definition for a set of hosts, we need to
include maximum physical address size in the result to make sure it is
compatible with all hosts even if their supported physical address sizes
differ.
* conf: Properly handle slots for non-DIMM ``<memory>`` devices
Memory devices such as ``virtio-mem`` don't need a memory slot as they are
PCI devices. ``libvirt`` now properly accounts the memory slots for such
devices as well as specifying the ``slots`` attribute of the ``<maxMemory>``
element is no longer needed unless DIMM-like devices are to be used.
* ``passt`` log and port forwarding improvements
Libvirt now ensures that the ``passt`` helper process can access the
configured log file even when it's placed in a directory without permissions.
The ``<portForward>`` element of a passt-backed interface can now omit the
``address`` attribute as it's enough to specify a ``dev``.
* Bug fixes
* lxc: Allow seeking in ``/proc/meminfo`` to resove failure with new ``procps`` package
New version of the ``free`` command from ``procps`` package seeks into the
``/proc/meminfo`` file, which was not supported by the instance of the file
exposed via LXC causing a failure.
* qemu: Fix rare race-condition when detaching a device
The device removal handler callback function didn't re-check the state of
the unplug operation after a timeout, which could rarely cause that the
device was removed from the VM but not the definition.
* qemu: Fix NUMA memory allocation logic
QEMU allocates memory via the emulator thread thus that has to be allowed
to access all configured NUMA nodes of the VM rather than just the one where
it's supposed to be pinned.
* qemu: Fix setup of ``hostdev`` backed ``<interface>``
The proper steps to initialize the host device were skipped for interfaces
due to a logic bug preventing start of VM which used them.
Enjoy.
