That is normal behavior. Snapshotting itself is a fast process, but restoring means merging and rolling back. It's easier to protect a snapshot and clone it into a new image and use that one. Afterwards you can flatten the image to detach the clone from the parent. Never tried if this can be done live. -- Wido den Hollander 42on B.V.
