That's how it was back in the old days. Then libvirt introduced storage
migration, but requiring users to pre-create storage on destination
themselves. And just recently I taught libvirt to automatically
pre-create the storage. However, not for all disk types.

If a disk on destination is missing, it's likely broken guest ABI
libvirt should have not allowed migration in the first place. How come
the migration was allowed?
