What do you think about the following syntax:
migrate [-d] URI
[block:default_copy_level:[<device:copy_level>,.....,<device:copy_level>]
copy_level: 0 - flat copy.
            1 - copy only first COW level.
            ..
            n - copy all COW levels.
default_copy_level: use this copy level for all devices that are not
mentioned in the migrate command.

I intend to implement it this week, I am planning to implement on the first
phase only copy levels 0 and 1.
It suppose to solve the major problem today that a guest has one block
device that needs to be copied flat and the other block device that needs
to be COW copy.
