I found this - http://www.howtoforge.com/vboxheadless-running-virtual-machines-with-virtualbox-2.0-on-a-headless-ubuntu-8.04-server - but it's only for Ubuntu :| – warren Jan 18 '12 at 00:07

Any reason you can't use, say, KVM or Xen? – Shane Madden Jan 18 '12 at 00:51

@Shane Madden - in this specific case, the headless machine is in a backup data center with no physical access, so I'd like to use something that isn't *quite* as low-level as KVM .. plus, we're already using VirtualBox for testing on local machines – warren Jan 18 '12 at 01:07

You can just install the VirtualBox package onto the headless machine like you would any other one (https://www.virtualbox.org/wiki/Linux_Downloads). Afterwards, VirtualBox can be controlled via the vboxmanage command, documented in detail on http://www.virtualbox.org/manual/ch08.html . In order to set up your VMs easily (with graphical OS setup and so on), I recommend, however, to create and install them in a graphical environment and then copy the hard disk images to your headless machine.
