emulators/virtualbox-ose unable to run CloudReady (Chromium OS)

Seeing `swrast_dri.so` in the third shot, I assume that the Neverware's 
virtual machine `CloudReady-Home-v78-x64.ova` is not compatible with 
VirtualBox on FreeBSD.

Any suggestions on how to work around the issue?

A significant obstacle: the console remains visible for only a few 
seconds at a time. After each blackout, it's necessary to (again) log in 
at the command line.

(I don't intend to buy a Chromebook. I would like to try Chromium OS in 
a virtual machine.)
