Title:
  block_device mapping identifies ephemeral disks incorrectly

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Ephemeral drives are destinaton == local, but the new bdm code bases
  it on source instead.  This leads to improper errors:

  $ nova boot --flavor m1.tiny --block-device source=blank,dest=volume,bus=virtio,size=1,bootindex=0 test
  ERROR (BadRequest): Ephemeral disks requested are larger than the instance type allows. (HTTP 400) (Request-ID: req-53247c8e-d14e-43e2-b01e-85b49f520e61)

  The code is here:

  https://github.com/openstack/nova/blob/106fb458c7ac3cc17bb42d1b83ec3f4fa8284e71/nova/block_device.py#L411

  This should be checking destination_type == 'local' instead of source
  type.
