You'll find little official support on the lists for problems you have due to the hypervisor, but I've found that OpenBSD works great in VirtualBox. You can't get VirtualBox Guest Additions working, but judging from the popularity of this post I wrote almost 8 years ago, and the comments on it, this trick still works for many people to get an OpenBSD VM into full-screen mode.
