You remove that snapshot file (or move it aside) and create the samefile again with exactly the same command you used above. Then you're back to the state as of 'guestqcow2'. "snapshot1" only stores the delta relative to "guestqcow2", so all your changes are in that file. To undo them, you just need to to forget those changes and start with a new snapshot file, where the delta is zero. Hope that helps.
