Yes, as long as the VGA card is configured (in 4.3 you can actually
disable it using CLI) it needs a framebuffer. Wonder why it's worth
implementing a framebuffer-less VBoxHeadless look-alike.<br>
<br>
It's required to get at the screen content, and it was considered
too unusual to have a VGA card and no framebuffer. When disabling
VGA it's a valid setup.<br>
