Bug description:
  When an instance with attached Cinder volumes is block migrated, the
  Cinder volumes are block migrated along with it. If they exist on
  shared storage, then they end up being copied, over the network, from
  themselves to themselves. At a minimum, this is horribly slow and de-
  sparses a sparse volume; at worst, this could cause massive data
  corruption.
