OpenBSD as guest in Virtualbox

Does this work? Yes it does currently. With OpenBSD 5.0, 5.1 an VirtualBox 3.2.

Without hardware virtualization on my CPU I had to start VirtualBox differently than normally, though:

VBoxSDL –norawr0  –startvm NAMEOFMACHINE &

Then it should run ok. I run this setting on a Debian 6.x Squeeze since some years. So it does not need VT-x or AMD-V hardware virtualization support, as Oracle says.

–norwar0” means  “disable raw ring 3”. I still dont really understand this completely. But Wikipedia also talks about the rings.
