Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing feedback. Your work is greatly
appreciated.
* New features
* Introduce Hyper-V ``host-model`` mode
Similarly to CPUs, ``host-model`` mode expands available Hyper-V
enlightenments at domain startup into the live XML so that's obvious which
enlightenments are enabled.
* Add support for Hyper-V ``spinlocks`` "never notify" mechanism
The ``retries`` attribute - which defines after how many failed
acquisition attempts to notify the hypervisor - can now hold the
special value of 4294967295 which means to never notify the
hypervisor.
If the ``retries`` attribute is omitted this value is used.
* ch: Network hotplug Support
Users can now attach and detach network interfaces of Cloud Hypervisor
domains at runtime.
* bhyve: NVMe device support
Domain XMLs now can use NVMe devices::
<disk type='file'>
<driver name='file' type='raw'/>
<source file='/path/to/disk.img'/>
<target dev='nvme0n1' bus='nvme'/>
</disk>
* Improvements
* qemu: Improvements to USB controller model selection
Virtualization-friendly USB3 controllers are now used in more situations,
Intel-specific USB controllers are relegated to x86 guests, and model
selection overall behaves more consistently across architectures.
* qemu: Validate Hyper-V enlightenment dependencies
Some Hyper-V enlightenments may require some other enlightenments to be
turned on. Libvirt now validates these for new domains.
* qemu: Introduce virtio options for virtio memory models
Both virtio-mem and virtio-pmem memory models are virtio devices and as
such now support setting various virtio knobs (iommu, ats, packed,
page_per_vq) common to other virtio devices.
* wireshark: Adapt to wireshark-4.6.0
Libvirt's wireshark dissector plugin adapted to changes made to wireshark
dissector API in its 4.6.0 release.
* qemu: 'manual' disk snapshot mode improvements
The 'manual' snapshot mode now ensures that also metadata of the images is
written out to disk so that user can take snapshots of e.g. qcow2 image
safely.
* Bug fixes
* ch: Load ``ch.conf`` from ``SYSCONFDIR``
Previously, the ``ch.conf`` file for ``ch:///system`` URI was mistakenly
loaded from a path under ``LOCALSTATEDIR`` (``/var/...``). This is now
fixed and the configuration file is loaded from the ``SYSCONFDIR``
(``/etc/...``) location where it's also installed.
Enjoy.
