Hi,
this is my first post in this mailing list. I hope this is the correct way
to post it here.

I have issue when enable the Vt-x/AMD in Virtuabox, after the virtual
machine boot up. kernel panic happened.

I currently using Virtualbox version:
$ pkg info |grep virtual
virtualbox-ose-4.3.20_4        General-purpose full virtualizer for x86
hardware
virtualbox-ose-kmod-4.3.20     VirtualBox kernel module for FreeBSD
