Both my undergrad and grad OS courses used xv6 and I can tell you that the easiest way to get hacking on it is to spin up a VM (I used vagrant for this since I just wanted headless) and run it in QEMU. MIT has a patched version available that has some handy debug features. Feel free to contact me through keybase and I can provide you all the scripts I used.

Thank you! In the end, the source is so easy to read that I didn't actually need to build it all that much, but if I ever do, I'll get in touch :)
