this one looks more straightforward (no network interfaces config). http://www.howtogeek.com/117635/how-to-install-kvm-and-create-virtual-machines-on-ubuntu/?PageSpeed=noscript
Unfortunately I can't try it right now since my wifi doesn't work anymore. Hopefully it's just a software issue related to me messing with the config.
It's too bad because it looks like a great replacement to Virtualbox.
