Virtualbox has a headless from the command line you can use "vboxmanage
controlvm (params)"

This guy uses an init script to launch on boot in ubuntu:

Also in the latest version of virtualbox it has a check box for -Vt cpu
extensions.

As for 3D I'm with you Noah. Life would be very nice if that were to happen=
