It says yes or no depending on the kernel you're using.
Oh, and if you don't want to fuss with plist files, you can simply issue this command: sudo systemsetup -setkernelbootarchitecture x86_64 And to go back, change the architecture to i386. You could also use a simple (and quite mac-like) method: hold down the 6 and the 4 on your keyboard during startup (3 & 2 for the reverse), but that's only for the one time. Unfortunately I haven't used VirtualBox, so I can't help you with that.
