Sure it is possible. You need to have the datastore that holds the
images shared and mount it in every node. Then you'll make the system
datastore(0) local and configure it to use qcow tm drivers. Make sure
that /var/lib/one/datastores/0 is not mounted from the shared storage
in the nodes as this is where the deltas will be written.
