[ovirt-users] Delete snapshot

Hi all, I created a snapshot on a VM, which I'd like to delete. No further snapshots were made, only this single only. The button delete is greyed out though, untill I power off the VM. I thought with live merge this wasn't needed any more, or am I mistaken? Engine running on CentOS 6 x64, latest stable versions of all packages. Am I missing something? -- Met vriendelijke groeten / With kind regards, Johan Kooijman
