I need to get the current snapshot name, so that I can revert to it later. Here's the process:
1. Power on
2. do something (run a program in guest)
3. shut down
4. snapshot(name)
--at this point, I need to revert to the snapshot I started from.
there doesn't seem to be anything built in, do I have to build this myself? Any quick (even if hacky) ways to do this? Such as parsing a file?
