FIXME the test VM's are using 80 GB disks, so probably we can increase the volume size
 from 10 to 24 GB.

The loopback volume backing file is sparse allocated [1,2] so the real size only
 necessary if we write a lot to the volumes.

The cinder multi-back end is turned on, the second back-end could use nfs volumes,
which also uses the sparse allocation. [3]

The nfs back-end does not supports snapshots yet, but it deletes the files after
the volume deleted.
