[libvirt] [PATCH 2/3] Add test for persistent domain snapshot management
From: "Daniel P. Berrange" <berrange(a)redhat.com>
The test case validates the core lifecycle operations on
persistent domains with snapshots. A persistent domain
should allow snapshots to be created & deleted while both
running and shutoff. It should forbid undefine of the
domain when it has snapshots present.
