RHEV 3.5.1 Live Snapshot Deletion

Has anyone updated their environment to this level and got this working? This could be a game changer since it opens up the possibility of VM-level backups -- something we have in our VMware environment but could only hope for (for years...) in our RHEV environment. I'd love to hear experiences of any early adopters. We're still on RHEV 3.4 -- I'm a little gun-shy on the major version upgrades.

Thanks,
Daniel
