Public bug reported:

Instance is failing with booting from volume

 [req-e1b1ac9c-3394-44c6-8453-b05f41f2aa16 admin admin]  Instance failed to spawn
  Traceback (most recent call last):

      if state.lower() != 'poweredoff':
  AttributeError: 'int' object has no attribute 'lower'

Because in nova/compute/power_state.py, all states are in index, so
state should be int not str. So the driver code need to be updated
accordingly.

Command to reproduce in devstack(all repos are in master level):
nova boot --nic net-id=<net-id> --flavor <flavor-id> --block-device source=image,id=<image-id>,dest=volume,size=2,shutdown=preserve,bootindex=0 mystanceFromVolume1
