features: - | With the libvirt driver and libvirt version 7.3.0 or newer, mediated devices for vGPUs are now persisted across reboots of a compute host. .. note:: After a compute host reboots, if you have a GPU that supports SR-IOV, then the virtual functions for the GPU must be enabled again before instances will be able to use their vGPUs. Please see https://docs.openstack.org/nova/latest/admin/virtual-gpu.html for more information.
