First, I am not really convinced  - You want only use that make VM backups?

I am asking because this does not have snapshot semantics if you have more
that one disk. Also, on a reasonable storage, you can simply make a snapshot,
which is much faster as easier to manage.

There are so many options when people talk about backups, so I want to 
make sure I understand your needs.

Second, I guess you could add an option to move_disk which avoids 
changing the config. Changing the config can be done with other
API calls (remove/add disk).
