Alright, so after many hours of search, I think I know the answer. I will post what I know here in case some one else needs it one day.
To enable Intel VT technologies there are 3 things needed:
- Processor that supports VT-x
- Motherboard with chipset that supports VT-d
- Bios that supports VT-d as well
Turns out, the reason I can't enable VT, it's because my motherboard doesn't support VT-d, and although my processor supports VT-x, that doesn't matter. It's all or nothing.
How to know if a motherboard supports VT-d? That greatly depends on
the chipset it has. In the case for Intel these posts were helpful:
So after hours of searching for the Clevo W150ER motherboard specs
(Review Clevo W150ER Barebone
Notebook),
I found that it holds the Intel's Panther Point Model
HM76 which does not support
Intel VT-d.
Please notice that supporting VT-d is not enough to support Intel VT.
The processor must support Intel VT-x, and the Bios must also support
it. If you require special network use, a special VT flag is also
required, though I cannot remember it.
Hope it helps you all.
