libvirt users - Mar 2014 - can I undo the snapshot apply of a qcow2 image

Hi all 
I have a problem.
Two days ago , I used kvm-img create a snapshot of an qcow2 format image.
And  today I apply the snapshot of this image.

The question is can I recovery the image to the last point .
 I mean Undo this snapshot apply

No, there is no 'undo' operation. virt-manager will explicitly warn the
user
here that reverting to a snapshot is dangerous (unless you take a snapshot
right before reverting, since that will save your previous disk state).
