I hope I saved you some time and headaches. So in the end, it is possible (I've done it), but you will be disappointed with the performance. Support for SMP will be provided in a future release. If your Mac appears to be stuck on a blank screen, follow these steps.

Mac OS X guests only work with one CPU assigned to the VM. A blank screen (black, gray, or blue) should appear once or more during startup. “Video Modes in EFI” for more information on how to change EFI video The graphics resolution currently defaults to 1024x768 as Mac OS X falls back to the built-in EFI display support. 04 in a VirtualBox (host OSX Lion) and I also have exactly the same.

Oracle VM VirtualBox does not provide Guest Additions for Mac OS X at this time. When I boot the VM it only shows the black screen with a blinking cursor. See Sectionģ.1.1, “Mac OS X Guests” and check the Apple software license conditions. For details about license and host hardware limitations. Mac OS X guests can only run on a certain host hardware. The better option would be to use VMWare, as they are supporting it. My experience with doing this multiple times shows, that it is not worth it. The performance of the guest will be quite bad and not what you would expect. I am sorry but running Mac OS X on Virtualbox in linux will be very hard and it would require some editing of configuration files of the VM image itself, along with additional software in the guest, and probably further modifications.
