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.
