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.
