Public bug reported:

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.
