Description of problem: Cannot create snapshot of running VM. Version-Release number of selected component (if applicable): rhevm-3.5.0-0.12.beta How reproducible: Always Steps to Reproduce: 1. Try to create snopshot of VM. 2. It will fail with "Cannot create Snapshot. Opetration not supported by QEMU. 3. Actual results: "Cannot create Snapshot. Opetration not supported by QEMU. Expected results: Snapshot should be created without error. Additional info:
this happens when qemu on the host does not support this feature, i assume you need to upgrade libvirt/qemu what versions of vdsm/libvirt/qemu running on your host?
might be duplicate of bug 1149460 which is result of libvirt bug 1149667
Hi, This bug may be also relevant: https://bugzilla.redhat.com/show_bug.cgi?id=1159211 First thing is to check libvirt status. Please follow these instructions: https://bugzilla.redhat.com/show_bug.cgi?id=1158469#c2 After libvirt, you may want to check wath VDSM knows. On the affected host: # vdsClient -s 0 getVdsCaps | grep -i livesnap Engine will just read this value without additional logic. Please note that VDSM is just a middleman here, so libvirt is the authoritative source. If libvirt is behaving correctly, you may have hit bz1159211. It is possible if you update libvirt after the affected host was added to oVirt Engine. If so, unfortunately there is no workaround until next beta (at that point this issue will just disappear), so a manual intervention is needed: https://bugzilla.redhat.com/show_bug.cgi?id=1149460#c32 (equivalent instructions here but with worse SNR https://bugzilla.redhat.com/show_bug.cgi?id=1159211#c0 )
please see steps to proceed from Francesco in comment 5
Hello, following are the outputs: # vdsClient -s 0 getVdsCaps | grep -i livesnap liveSnapshot = 'false' # virsh -r capabilities | grep -i snapshot <disksnapshot default='off' toggle='no'/> <disksnapshot default='off' toggle='no'/> So I think we can mark this as duplicate of 1149460.
