[libvirt] [PATCH 2/2] rbd: Implement buildVolFrom using RBD cloning

2015-12-23 Thread Wido den Hollander
RBD supports cloning by creating a snapshot, protecting it and create a child image based on that snapshot afterwards. The RBD storage driver will try to find a snapshot with zero deltas between the current state of the original volume and the snapshot. If such a snapshot is found a clone/child
