Title:
  domain xml not well defined when using virtio-scsi disk bus

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  When using virtio-scsi we should be able to attach up to 256 devices
  but because the XML device definition do not specify which controller
  to use and place on that on that one, we are currently able to attach
  no more than 6 disks.

  step to reproduce the issue:

  - glance image-update --property hw_scsi_model=virtio-scsi <image>" to creates the virtio-scsi controller
  - glance image-update --property hw_disk_bus=scsi <image>" disks will be using scsi

  Start instance with more than 6 disks/volumes
