Description Daniel Erez 2015-07-07 12:05:38 UTC

Description of problem:
Live snapshot of a VM with Cinder disks should be implemented using libvirt freeze/thaw API[1,2] (in order to avoid data inconsistency in the snapshot disks).

Comment 1 Ori Gofen 2015-11-17 12:38:16 UTC

Live snapshot is supported now on cinder volumes with ceph backend, note that this operation fails on logs, though successful de facto.
marking as Verfied on 3.6-0.2.
separate bugs will be opened

Comment 2 Sandro Bonazzola 2015-11-27 07:52:31 UTC

Since oVirt 3.6.0 has been released, moving from verified to closed current release.
