step 1: boot a simple instance
step 2: stop the running instance which is booted in step 1
step 3: migrate the instance to same host，but the driver in the host doesn't support migrate to same host
step 4: nova show uuid(instance uuid), the instance's vm-state becomes error, and the fault show {"message": "Unable to migrate instance ( instance uuid) to current host (hostname)
step 5: nova instance-action-list uuid(instance uuid), you will see migrate error.
