Re: [libvirt] A question about booting from the snapshot image by specifying snapshot id in Libvirt

I'm not that familiar with sheepdog, but I'll give it a shot: id 1 is a static point in time. But you booted your guest, which means you have made modifications since that point in time. Those modifications have to be stored somewhere. You can't rewrite id 1, so sheepdog auto-created id 4 as the storage for all changes since you booted from the point in time that id 1 was recording.
