I have just tagged v8.2.0-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,
Jirka
The 8.1.0 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.
* New features
* qemu: Add hvf domain type for Hypervisor.framework
It works on Intel machines as well as recent machines powered by Apple
Silicon. QEMU 6.2.0 is needed for Apple Silicon support.
* qemu: Support mode option for dirtyrate calculation
Introduce ``virDomainDirtyRateCalcFlags`` as parameter of
``virDomainStartDirtyRateCalc``, which is used to specify the mode of
dirty page rate calculation.
Add ``--mode`` option to ``virsh domdirtyrate-calc``, which can be
either of the following 3 options:
``page-sampling, dirty-bitmap, dirty-ring``.
Add ``calc_mode`` field for dirtyrate statistics returned by
``virsh domstats --dirtyrate``, also add ``vCPU dirtyrate`` if
``dirty-ring`` mode was used in last measurement.
* Improvements
* packaging: sysconfig files no longer installed
libvirt used to provide defaults in various /etc/sysconfig/ files, such
as /etc/sysconfig/libvirtd. Since these files are owned by the admin, this
made it difficult to change built-in defaults in case such file was
modified by the admin. The built-in defaults are now part of the provided
systemd unit files, such as libvirtd.service. These unit files continue
to parse sysconfig files, in case they are created by the admin and filled
with the desired key=value pairs.
* virnetdev: Ignore EPERM on implicit clearing of VF VLAN ID
Libvirt will now ignore EPERM errors on attempts to implicitly clear a
VLAN ID (when a VLAN is not explicitly provided via an interface XML
using a 0 or a non-zero value) as SmartNIC DPUs do not expose VLAN
programming capabilities to the hypervisor host. This allows Libvirt
clients to avoid specifying a VLAN and expect VF configuration to work
since Libvirt tries to clear a VLAN in the same operation
as setting a MAC address for VIR_DOMAIN_NET_TYPE_HOSTDEV devices which
is now split into two distinct operations. EPERM errors received while
trying to program a non-zero VLAN ID or explicitly program a VLAN ID 0
will still cause errors as before so there is no change in behavior
in those cases.
* Bug fixes
* Remove unix sockets from filesystem when disabling a '.socket' systemd unit
The presence of the socket files is used by our remote driver to determine
which service to access. Since neiter systemd nor the daemons clean up the
socket file clients were running into problems when a modular deployment was
switched to monolithic ``libvirtd``.
* qemu: Fixes of fd passing during hotplug and hotunplug of chardevs
FDs used as chardev backing are now properly removed when hot-unplugging
a chardev from qemu and hotplugged chardevs now properly use ``virtlogd``
to handle the input and output from qemu.
* RPM: Run pre/post-install steps on ``daemon-driver-storage-core``
Previously the pre/post-install code was part of the meta-package which
installed all storage driver sub-packages thus a minimalistic install
of the storage driver didn't behave correctly.
Enjoy.
