Title:
  Reboot operation fails if force_disk_config is switched to True after
  spawning

Status in OpenStack Compute (nova):
  Expired

Bug description:
  A hard reboot operation fails if force_disk_config is switch to True
  after spawning the instance without a config drive.

  This was found using the libvirt driver, I'm not sure if it affects
  other drivers.

  Steps to recreate would be:
  1. Spawn an instance without a config drive
  2. Change force_config_drive to True in your nova.conf
  3. Restart nova-compute
  4. Attempt to reboot the instance

  An error similar to the following message will be displayed in the
  nova compute logs:
