@Photor Frustation! Wanted to play with it - but I always end with a gray screen, no mouse, no keyboard, no chance to quit. I always have to shutdown the VirtualBox-machine.
I have no idea, what happened. I have updated VirtualBox in Archlinux host, but that should not affect the FreeBSD in the box. I have already checked against FreeBSD handbook - found nothing special. No idea at the moment.
