Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing feedback. Your work is greatly
appreciated.
* New features
* network/qemu/lxc: support vlans on standard Linux host bridges
The network, qemu, and lxc drivers now support (using the
``<vlan>`` subelement) vlan tagging and trunking on network
interfaces connected to a standard Linux host bridge.
* qemu: Add support for direct and extended tlbflush features
Domains can now utilise more tlbflush hyperv features.
* Improvements
* ch: Enable user aliases
User can now specify custom aliases for devices in domain XML
* qemu: Grab a QUERY job when formatting domain XML
Under some specific conditions it might have happened that domain XML did
not contain runtime information or returned an XML that's in process of
changing (e.g. by a thread that's hotplugging a device). Formatting domain
XML now serializes properly with other threads.
* virtiofs: Allow read only mode
The ``<filesystem/>`` with `virtiofsd` backend can now use ``<readonly/>``
tag to export underlying filesystem in read only mode.
* qemu: allow migration of vGPU from mdev device <-> SRIOV VF device
Some GPU vendors are switching from using vGPUs creating using
mdev and identified with a uuid, to vGPUs created as SRIOV VFs and
identified by their PCI address, and want to support live
migration from a host using one type of vGPU to the other
type. This is now possible.
* Bug fixes
* qemu: tpm: do not update profile name for transient domains
Fix a possible crash when starting a transient domain which was
introduced in the previous release.
* qemu: Fix snapshot to not delete disk image with internal snapshot
When a VM has internal snapshot that is parent to external snapshot and user
reverts to the internal snapshot and deletes the external snapshot libvirt
would delete the disk image containing the internal snapshot. This would
result in data loss.
* qemu: Do not format invalid XML with hyperv features in passthrough mode
When hyperv features were specified together with ``mode="passthrough"``
libvirt parsed and formatted such features in the domain XML even though
they were not used at all, resulting in XML that is not valid based on our
schema. This is now fixed by not parsing any specified features when the
passthrough mode is used.
* qemu: Fix a crash when starting a domain with ovs bridge and QOS
* cpu: Add missing -v1 variants for CPU models
Some CPU models (mostly old ones) were missed when versioned CPU model
names were introduced in the previous release.
* qemu: Fix false error when recovering failed post-copy migration
In some cases libvirt would report a failure to recover post-copy migration
even though the recovery started just fine and migration would eventually
successfully finish.
Enjoy.
