This might not be too relevant to OS X, since I am running Ubuntu, but I'll put it here for the record anyway, in case it is useful to someone:
At some point when the virtualbox image wasn't working for me I recompiled the kernel module this way. I think that I did it after getting a more informative error message from virtualbox that suggested it as a solution. I also had the problem that I had to unload the KVM kernel modules before virtualbox would work. I think that I installed KVM sometime in the past to try it out, but I don't actually use it. (Virtualbox actually gave me an intelligent error message here.) I originally thought that the final thing that I did to make the virtualbox image go from not working to working was increase the video ram, but I have since tried decreasing the video ram, and the image still works. Also, somewhere in between I created a different virtualbox image to install Windows on, and I may have rebooted by computer once or twice. Anyway, these are at least some of the various things that I did, and some combination of these actions made the image work when it originally did not. I wish I had been more systematic so that I knew exactly what I did. Another thought that occurs to me is: What does virtualbox do when you ask it to use VT-X/AMD-V and your processor does not support it? Will it cause an error, or will virtualbox just ignore the option?
