I run lots of stuff in VMs because I want to experiment or because I'm not sure if something's going to work right. It's nice to just take a snapshot and then do whatever task you wanted to do. If everything gets screwed up, it's no big deal. Just roll back to that last snapshot you made and start over. I do the same thing on my FreeBSD machines when installing updates (thanks to ZFS).
