hi list, I realize there's a command called "rbd lock" to lock an image. Can libvirt use this to prevent virtual machines from being started simultaneously on different virtualisation containers? wogri
Yes - that's the reason for lock command's existence. You have to be careful with things like live migration though, which will have the device open in two places while migration completes. If libvirt could use rbd locks like it uses its sanlock plugin, it would be able to deal with this correctly.
