How to remove guest in "Reverting to snapshot..." state

I have a linux guest stuck in the "Reverting to snapshot..." state for close to an hour now.

I've used "Force Quit" several times to try and kill it, but the linux guest still shows "Reverting to snapshot...".

I just want to remove this guest and start over. But I can't do anything with that guest at this point.

Help!

 

Well, it's now been stuck in this state all day. How to get rid of this machine definition?

 

I've had the same problem. Running Parallels Desktop 7 for Mac. It's been in the "reverting to snapshot" state for 8 hours now and appears to be doing nothing. This is really frustrating as we're using Parallels in a production environment.

I loath to kill the app lest I can't restart the VM. I do have a backup of the image from a few days back so not all is lost.
