I'm not sure but maybe it could be possible to use blockdev-add to add the unused disk inside qemu
(without exposing it inside the guest with device_add).
Like this, maybe it could be possibly work.

Maybe we should disallow to migrate when either snapshot exist or unused disks are used?

Also some notes I have I mind : 

- We should avoid migration if snapshot exist. 
(because disk sync will delete snasphots) 

- We need to sync unused disks

I didn't known about the blk=> option in qmp migrate. 





It's already for some time. I were doing migrations with blk a two years ago :)
