I know that using block storage like Cinder you can evacuate instances from hosts, but in my case we are not yet using Cinder or other block storage solutions, we rely on local ephemeral storage, configured on using LVM

Nova.conf
[libvirt]
images_volume_group=vg_ephemeral
images_type=lvm

Is it possible to evacuate (migrate) ephemeral instances from compute hosts and if so does any one have any experience with that?
