Import 83:b569bb25a8f08a15381b022ee143d7f205976604 from xen-api.hg, minus the
Makefile patch.
[XEND] Remove blank image file generation for QCOW images.
There is no need for a blank backing store, although this means we
have to find a new way to determine how much virtual disk space is
free in the StorageRepository.
Beginnings to attempt to supoprt HVM guests.
