The 11.9.0 release of both libvirt and libvirt-python is tagged and signed tarballs 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 * 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. Jirka
