I am quite unsure about that, So far, we have many storage types which simply
do not have any native snapshot support, for example:
* iscsi: that standard simply does not define snapshots in any way
* lvm: snapshots are simply not usable on shared storage
* /dev/xyz: block devices are not aware of snapshots
Putting qcow2 (or better qcow3) on those devices would solve the problem? If that works,
there is no more need to use nexenta snapshot support?
