Textbased installation of VMs in VirtualBox

[Linux for blind general discussion]

It's been a minute since I used VirtualBox, but last I knew, you could 
make your vm's right from a terminal or text mode. It once had, and 
hopefully still does have, a command line, so you can start from a shell 
without having to use the graphical interface at all. There should even 
be a headless mode, which if I remember correctly exposes a serial 
console or similar. Unfortunately I don't know the specifics of how to 
use these features, but I am aware that they exist, so this should help 
a little.
