nova evacuate

I just tried to simulate a hardware error with Openstack (Liberty) and Hyper-V. I forcfully shut down one node and tried to nova evacute the instances from the failed node. But that failed with an InstanceRecreateNotSupported error.

2017-01-27 11:56:22.194 4956 ERROR oslo_messaging.rpc.dispatcher     raise exception.InstanceRecreateNotSupported
2017-01-27 11:56:22.194 4956 ERROR oslo_messaging.rpc.dispatcher InstanceRecreateNotSupported: Instance recreate is not supported.

Is this a limitation of Nova Hyper-V? Is there any way to recover the failed instances?
