Hello, The first thing the 3.5 release notes talk about is Live Merge of snapshots and I've been dying to try that out. Problem: I think my environment is completely up to date now, but the "Delete" link on VM snapshots remains greyed out when the VM is running. Going via "Storage" -> Domain name -> "Disk Snapshots", clicking "Remove" is possible (UX inconsistency), but it stops with "Error while executing action: Cannot remove Disk Snapshot. At least one of the VMs is not down." What is needed, besides the following, to make live merge work? - oVirt Engine Version: 3.5.0.1-1.el6 - Data Center Compatibility Version: 3.5 - Host OS: RHEL - 6 - 6.el6.centos.12.2 - KVM Version: 0.12.1.2 - 2.415.el6_5.7 - Libvirt Version: libvirt-0.10.2-46.el6_6.1 - VDSM version: vdsm-4.16.7-1.gitdb83943.el6 - Live Snapsnot Support: Active VM has been restarted to make sure it's running on the latest qemu-kvm. Please advise, thank you in advance. Best regards, Martijn Grendelman

Hi Martijn I am running up-to-date EL7 hosts and was also disappointed to find Live Merge was not functional (yet). As I understand it the live merge feature depends on some quite new features in libvirt and qemu which are only available at the moment in the Fedora virt-preview repo. More information at this link http://www.ovirt.org/Features/Live_Merge. As to be expected libvirt and qemu packages provided in EL6 and EL7 will lag a bit behind upstream for good reasons such as ensuring things are well tested and proven reliable. I am sure Red Hat are very keen to get this much overdue feature into their RHEV product so I don't expect the wait for updated EL packages will be too long.
