VM processes must be suid root (they're dropping the privileges for good
immediately after starting, so don't worry that Joe User running VMs can
turn the system upside down). VBoxManage is a simple API client which
won't ever have a VM running inside, so it doesn't need it.
VBoxHeadless again does.

Short term it's probably impossible (I suspect even when using the GUI
exclusively to show the screen of a headless VM, i.e. using the separate
UI case which has limitations). Long term it's the direction in which
we're heading, by making the separate UI case the only possibility.
