<div dir="ltr">Hi Martijn<br><br>I am running up-to-date EL7 hosts and was also disappointed to find Live Merge was not functional (yet).<br><br>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 <a href="http://www.ovirt.org/Features/Live_Merge">http://www.ovirt.org/Features/Live_Merge</a>. 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.<br><br>Regards<br>Paul<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Nov 12, 2014 at 11:55 PM, Martijn Grendelman <span dir="ltr"><<a href="mailto:martijn.grendelman@isaac.nl" target="_blank">martijn.grendelman@isaac.nl</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello,<br>
<br>
The first thing the 3.5 release notes talk about is Live Merge of<br>
snapshots and I've been dying to try that out.<br>
<br>
Problem: I think my environment is completely up to date now, but the<br>
"Delete" link on VM snapshots remains greyed out when the VM is running.<br>
<br>
Going via "Storage" -> Domain name -> "Disk Snapshots", clicking<br>
"Remove" is possible (UX inconsistency), but it stops with "Error while<br>
executing action: Cannot remove Disk Snapshot. At least one of the VMs<br>
is not down."<br>
<br>
What is needed, besides the following, to make live merge work?<br>
<br>
- oVirt Engine Version: 3.5.0.1-1.el6<br>
- Data Center Compatibility Version: 3.5<br>
- Host OS: RHEL - 6 - 6.el6.centos.12.2<br>
- KVM Version: 0.12.1.2 - 2.415.el6_5.7<br>
- Libvirt Version: libvirt-0.10.2-46.el6_6.1<br>
- VDSM version: vdsm-4.16.7-1.gitdb83943.el6<br>
- Live Snapsnot Support: Active<br>
<br>
VM has been restarted to make sure it's running on the latest qemu-kvm.<br>
<br>
Please advise, thank you in advance.<br>
<br>
Best regards,<br>
Martijn Grendelman<br>
