If you are using 4.10, we do support migrations when a VM is in unknown (i.e. hypervisor is down) provided there is a shared storage. Next release (4.12) will include the ability to migrate in poweroff.
Meanwhile a work around, (there are two actually fake a hypervisor failure to get the VM in unknown and use the previous feature or fake a migration failure). I've not tested this myself so watch out: 1.- Update the kvm migrate script by adding at the very beginning something like: sleep 600 return We want to get the VM in MIGRATE state for a while 2.- Manually move the VM: Go to the hypervisor, and shut it down (i.e. virsh...); move the config files (those in ssh system datastore); got to the other hypervisor and manually create the VM. 3.- use onevm recover <vmid> success, the VM should become running in the new host. (The sleep'ed migrate operation should be ignored as the VM would be RUNNING) 4.- Undo the changes in the migrate script.
