Enhh, interesting. So it is not live snapshot? The VM must be paused
to do the snapshot in my engine. Also, I hit a bug to resume the VM
after the snapshot was done. The VM was always in pause state after I
clicked the resume button after the snapshot was done. I looked into
the VM by VNC and VNC console showed that the VM was in frozen state.
Has anyone seen these or has it been fixed in the upstream?
