Exactly, I could set up docker and start trying to run my own services and everything, when it stops working I could delete the whole VM and start fresh, I hate when a program doesn't work the first time I try to install it, I feel like I have no way to undo all the commands I copy/pasted and I'm tired of the hassle of reinstalling my OS all the time. This way I can setup a fresh VM, try to get something to work, if it works then I keep it in its little corner, it it doesn't I can just reset and go again. I'm starting to like this idea.
