I have an Ubuntu VM on my Thinkpad E430 I would like to occasionally use. There seems to be a problem with allowing the VM to access multiple cores. I have the latest BIOS according to the update utility. In BIOS, I cannot find any way to enable/disable VT-x. According to Oracle, features are locked or unavailable in MSR.

I have the ability to enable/diable virtualization in my bios. If I am not mistaken, this is one of the few computers where it is set on by default.
Under ubuntu do
$ grep -E avx /proc/cpuinfo
If there is a highlighted avx, it is already turned on. Though I am not sure if this will work under virtualbox.
If you are using ubuntu anyway, why not use WUBI? It basically installs ubuntu as a normal application in windows. You may even get better performance that way.
