Public bug reported: The persistent mdev feautre passes that flag but that flag was only supported since libvirt 8.10.0 so with older libvirt like 7.3.0 (min persistent mdev) or 8.0.0 (ubuntu 22.04) the persistent mdev feature cannot be enabled as nova-compute will fail due to the missing constant.
XML validation is just a nice to have feature so we can make that flag optional and only pass it if libvirt is >= 8.10.0 https://github.com/openstack/nova/commit/74befb68a79f8bff823fe067e0054504391ee179#diff-67d0163175a798156def4ec53c18fa2ce6eba79b6400fa833a9219d3669e9a11R1267 https://github.com/libvirt/libvirt/commit/d8791c3c7caa6e3cadaf98a5a2c94b232ac30fed ** Affects: nova Importance: Undecided Status: New ** Tags: libvirt mdev ** Tags added: libvirt mdev ** Description changed: The persistent mdev feautre passes that flag but that flag was only supported since libvirt 8.10.0 so with older libvirt like 7.3.0 (min persistent mdev) or 8.0.0 (ubuntu 22.04) the persistent mdev feature cannot be enabled as nova-compute will fail due to the missing constant.
