Re: [Users] live snapshots ovirt 3.1

It looks like it is possible now to create live snapshots; that is: on a running system. Creating fails however: [root@ovirtm ovirt-engine]# tail -f engine.log | grep -i snapshot 2012-06-19 09:50:07,046 INFO [org.ovirt.engine.core.bll.CreateAllSnapshotsFromVmCommand] (ajp--0.0.0.0-8009-7) [62433299] Lock Acquired to object EngineLock [exclusiveLocks= key: 88321641-ae26-4460-ab3e-30daa5a7fc1a value: VM 2012-06-19 09:50:07,213 INFO [org.ovirt.engine.core.bll.CreateAllSnapshotsFromVmCommand] (ajp--0.0.0.0-8009-7) [62433299] Running command: CreateAllSnapshotsFromVmCommand internal: false.
