DFBSD2 and virtualbox no compatible?

[Sdävtaker]

Hello,
I was trying to install a DFBSD2 in virtualbox (sun's virtual machine)
and it doesnt boot, acpi or not acpi the same. I was hitting some
config params, but nothing changes.
Did someone tried it before? I used to install some VMwarez with
DFBSD1.x with not problems, but company is migrating the
virtualization software to sun's virtualbox for some licences issue.
Any idea what can be wrong?
Thanks for any info.
