Evelina, is this failed in the automation tests? Banny is already working on it. Evelina, please note that a snapshot for a RO disk is not supported anymore by Libvirt, so Benny is fixing it by ignoring the RO disks when taking a VM snapshot. (In reply to Eyal Shenitzky from comment #1) > Evelina, is this failed in the automation tests? The flow is manual flow but we have a test with LSM so live snapshot is part of it. This is a regression for 4.4. This same automation TestCase was tested and passed on rhv-4.3.6-9 This bug report has Keywords: Regression or TestBlocker. Since no regressions or test blockers are allowed between releases, it is also being identified as a blocker for this release. Please resolve ASAP. Due to regression keyword targeting to closes release. dependent bug is fixed in AV 8.2.1, is there anything else to do? Verified on rhv-4.4.1-5 This bugzilla is included in oVirt 4.4.1 release, published on July 8th 2020. Since the problem described in this bug report should be resolved in oVirt 4.4.1 release, it has been closed with a resolution of CURRENT RELEASE. If the solution does not work for you, please open a new bug report. |
