I confirm that at least on f21 tc3 I was able to live delete snapshots, also into the active layer. See: http://lists.ovirt.org/pipermail/users/2014-November/029450.html and the whole thread. I hope that RHEL 7.1 (and CentOS) will have the merging into the active layer too.... and not only into the chain history. Gianluca
