I have a Lenovo H430-2558-1ZU with a Intel Core i3-2120 that is supposed to support Intel Virtualization Technology (VT-x) according to this. However, Virtualbox says that it doesn't support Intel VT-x. I checked with two other programs and they both said the processor did not have this feature. I checked the BIOS and it was listed and enabled. I am running Windows 8 Pro with Media Center, upgraded from the original Windows 7 Home Premium install. Is Windows 8 causeing this? The processor obviously supports this if it's in the BIOS.
