[libvirt] [PATCH 1/3] Add test for transient 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 transient domain
should allow snapshots to be created while running. It
should be possible to destory and restart the domain
and still have snapshots present.
