Headless (no gui) VirtualBox install?

[Ernie Pantuso]

My goal is to use TCL as a bare minimal host for VirtualBox VMs, leaving as much RAM and CPU power as possible for use by the guest OS (Windows XP/7, Mac OSX). I've seen this thread where they got it working as a gui, but I don't want to waste resources on the host gui.

I've seen a page howtoforge.com (/vboxheadless-running-virtual-machines-with-virtualbox-4.0-on-a-headless-ubuntu-11.04-server -- sorry, apparently I can't post external links) where they show how to do it, but they're using ubuntu server and I'm just noob enough that I'm not sure how to translate the procedure so it'll work with TCL. Any guidance would be greatly appreciated.

Just saying, KVM (Qemu) is very easy to run headlessly. Just install the kvm and qemu-kvm extensions.
