Public bug reported:
Currently, qemu image is always converted when resizing and migrating.
I guess this process is to prevent a original disk image corrupting when
expanding the disk size.
So qemu-img convert should be skipped when migrating and resizing
(when the disk image of new flavor is same the old one).
The qemu-img convert is IO heavy process, so I'd like to skip, if
possible.
