I have just tagged v7.8.0-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 7.7.0 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
* Add support for Fibre Channel VMID
New VM element ``<fibrechannel appid=''/>`` was added to allow users to set
their ``appid`` for each VM which will be used by kernel to create Fibre
Channel VMID. This allows various QoS levels, access control or collecting
telemetry data per VM.
* Improvements
* virsh: Allow XML validation for define of: storage pool, network, secret,
nwfilter, interface
* Add flag ``VIR_STORAGE_POOL_DEFINE_VALIDATE`` to validate storage pool
input xml. For virsh, users can use it as ``virsh pool-define --validate``.
* Add flag ``VIR_NETWORK_DEFINE_VALIDATE`` to validate network input xml. For
virsh, users can use it as ``net-define --validate``.
* Add flag ``VIR_SECRET_DEFINE_VALIDATE`` to validate secret input xml. For
virsh, users can use it as ``secret-define --validate``.
* Add flag ``VIR_NWFILTER_DEFINE_VALIDATE`` to validate nwfilter input xml.
For virsh, users can use it as ``nwfilter-define --validate``.
* Add flag ``VIR_INTERFACE_DEFINE_VALIDATE`` to validate interface input xml.
For virsh, users can use it as ``iface-define --validate``.
* Add SecurityManager APIs for labeling network devices
New ``virSecurityManagerSetNetdevLabel`` and ``virSecurityManagerSetNetdevLabel``
APIs are introduced and implemented in the Apparmor security driver.
The qemu driver uses the APIs to label vhostuser ports on hotplug and
restore labeling on unplug.
* vmx: Parse vm.genid and support super wide SCSI bus
The genid attribute is now reported for VMX guests. Libvirt can now
properly process super wide SCSI bus (64 units).
* qemu: Lifecycle action (``on_poweroff``/``on_reboot``) handling improvements
The handling of lifecycle actions was fixed and improved in multiple ways:
- ``restart-rename`` action was forbidden
The action was never properly implemented in the qemu driver and didn't
actually result in a restart of the VM but rather termination. The qemu
driver now rejects such configurations.
- ``preserve`` action was forbidden
Similarly to the previous case this never worked as the intended semantics
of the actions dictate. It's better to not allow it at all until there's a
proper implementation
- ``reboot`` action of ``on_poweroff`` now actually works
The guest OS is now rebooted instead of terminating the VM when the
``reboot`` action is used and the guest OS powers down. Note that it's
incompatible with ``on_reboot`` set to ``destroy``.
- Changes in action action of ``on_reboot`` are now updated with qemu
Libvirtd can now properly update the ``on_reboot`` action in qemu which
allows proper handling when changing between ``reboot`` and ``destroy``
actions. In addition, switching from ``reboot`` to ``destroy`` was
forbidden for older qemus which don't support the update API as the guest
could still reboot and execute some instructions until it was terminated.
* Bug fixes
* qemu: Open chardev logfile on behalf of QEMU
Guests with a logfile configured for their chardevs are now able to start
even when no virtlogd is configured.
* virhostmem: Handle numactl-less build in hugepages allocation/reporting
Some architectures don't have notion of NUMA (e.g. s390x) but do support
hugepages. Libvirt silently ignored requests to allocate/report hugepage
pool when built without numactl. This is now fixed and the pool can be
allocated/reported on properly.
* qemu: Record proper ``backing`` format for overlays of qcow2+luks images
Libvirt would record ``luks`` instead of ``qcow2`` into the metadata. In
practice this is a problem only when inspecting images manually via
``qemu-img`` as with libvirt users must use full specification of the
backing chain in the domain XML which supersedes information recorded in
the image metadata.
Enjoy.
