Public bug reported:

when the nova_compute service is stopped and evacuate the vm on the
host, then delete the vm when it is evacuating, the vm is local deleted
by nova-api, but the libvirt process is not terminated, and the
resources like GPU are still used by the vm process. from the code we
can see when the host is init and the evacuation status is failed, this
filter[1] cannot get the vm and the guest process is not
destroy.[1]https://review.opendev.org/plugins/gitiles/openstack/nova/+/refs/heads/master/nova/compute/manager.py#703
