Natalie - AFAIK, this was not the behavior in 3.6.1, making this a regression. Can you confirm/refute?

Comment 2 Maor 2016-02-04 10:06:54 UTC
The issue here is creating a snapshot with images and Cinder volumes.
There is a running VM with two Cinder disks and a live snapshot is being issued.

The operation makes 4 snapshots,
 2 of them for Cinder volumes,
 and the other 2 for images (memory and VM configuration).

The logic in the Command Coordinator has been changed drastically at ovirt 4.0.

Natalie, does the problem is only with the audit log, or there are other issues here?
