It seem the patch fixes this too. Until now I was never able to see snapshot details, Instead now I can see disk and nic details. See: https://docs.google.com/file/d/0BwoPbcrMv8mvQmlCZTZBYjBadmc/edit?usp=sharing OK, if I clone a VM from a snapshot of a running VM (CentOS 5.6) I start the clone and no problem at all. well done! Corner cases and problems 1) OK, if I clone a powered on VM from a snapshot with two disks and here you can find clone in action with webadmin gui and iotop on node that shows they are cloning in parallel.. well! https://docs.google.com/file/d/0BwoPbcrMv8mvZ3lzY0l1MDc5OVE/edit?usp=sharing The VM is a slackware 14 32bit with virtio disk that I obtained from a virt-v2v from CentOS 6.3+Qemu/KVM The problem is that the cloned VM recognizes the disks in reversed order See these images where sl1432 is master slcone is the clone disk layout in details pane seems equal with boot disk the one that appears as the second, but the master boots ok, the slave no. Disks are swapped Master VM disk details: https://docs.google.com/file/d/0BwoPbcrMv8mvSWNVNFI4bHg4Umc/edit?usp=sharing Clone VM disks details: https://docs.google.com/file/d/0BwoPbcrMv8mvM1N0bVcyNlFPS1U/edit?usp=sharing Page with the two consoles where you can see that vda of master becomes vdb of clone and vice-versa: https://docs.google.com/file/d/0BwoPbcrMv8mveFpESEs5V1dUTFE/edit?usp=sharing Can I swap again in some way? In VMware for example you can see and edit SCSI IDs of disks... 2) KO, if I clone a windows 7 VM from a snapshot (time 17:09) I get this on gui https://docs.google.com/file/d/0BwoPbcrMv8mvaW9OVW84WVI1dkU/edit?usp=sharing You can find the engine.log from server restart (at 17:06) here: https://docs.google.com/file/d/0BwoPbcrMv8mvTDQzRTFfbFgxX0E/edit?usp=sharing Are there any restrictions? The VM was powered off when taking the snapshot and making the clone. Gianluca
