Release of libvirt-9.8.0

The 9.8.0 release of both libvirt and libvirt-python is tagged and signed tarballs and source RPMs 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 * network: New metadata change event The network object now has a new event ID ``VIR_NETWORK_EVENT_ID_METADATA_CHANGE`` that can be used to get notifications upon changes in any of ``<title>``, ``<description>`` or ``<metadata>``. * qemu: Add support for vDPA block devices With a new enough version of qemu, libvirt will allow you to assign vDPA block devices to a domain. This is configured with:: <disk type='vhostvdpa'> <source dev='/dev/vhost-vdpa-0'> ... * Improvements * qemu: add nbdkit backend for network disks Up until now, libvirt supported network disks (http, ftp, ssh) by passing the URL to qemu and having the appropriate qemu block drivers handle the disk I/O. However, by handling the network I/O outside of the qemu process, we get several advantages, such as reduced attack surface and improved stability of qemu. Therefore, when available, libvirt will use nbdkit as a backend for these network disks and export an NBD disk to qemu. * virnetdevopenvswitch: Propagate OVS error messages When configuring OVS interfaces/bridges libvirt used to report its own error messages instead of passing (more accurate) error messages from `ovs-vsctl`. This is now changed. * Various virtio-mem/virtio-pmem fixes Now libvirt validates more values of virtio-mem and virtio-pmem devices, e.g. overlapping memory addresses or alignment. Enjoy. Jirka
