Title:
  Failed VM's not set to error state on exception

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) grizzly series:
  New

Bug description:
  We've identified that when an instance build fails because it has
  exceeded the number of retries (i.e. been tried on 3 different hosts)
  the upstream logic in the scheduler does not correctly set the VM
  state to ERROR.

  There is an exception handler for NoValidHost in
  manager.run_instance(), but it relies on request_spec[instance_uuids]
  to determine which instances to put into the Error State, and
  schedule_run_instance removes this value (as its normally about to
  split the request up into several separate requests).
