VirtualBox supports both UGA (Universal Graphic Adapter) and GOP (Graphics
Output Protocol) but FreeBSD loader uses GOP. Default GOP mode seems to be 2
(1024x768) and it panics kernel if the system memory is small. As a stopgap,
you may lower the resolution with VBoxManage, i.e.,
VBoxManage setextradata "VM name" VBoxInternal2/EfiGopMode N
where "VM name" is the name of your VM and N is from 0 to 5.
For example,
VBoxManage setextradata FreeBSD VBoxInternal2/EfiGopMode 1
will lower video mode to 800x600 for your "FreeBSD" VM. Please see the manual
for more information.
