I have a CLEVO w150erm, with a i7-3610QM processor, which supports Intel VT-x. However in order to use it I have to activate that option in the BIOS (or so that's what I believe) but I simply can't find it.

  • Is there a way to let me know if I have the Intel VT-x option enabled?
  • Where am I supposed to activate it in the BIOS? I simply can't find it :S
  • Do I have to use the EFI Shell to activate Intel VT-x? If yes how?

Be aware that even if your CPU supports VT-x, your motherboard might not. – Kitsune May 8 '13 at 0:31
No way ... how do I check that? – Flame_Phoenix May 8 '13 at 0:42

I did a quick search and found nothing definitive. The CPU supports it but the motherboard or BIOS may not.

You can download CPU-Z to at least confirm the CPU supports it

My guess is if there is not an option in the BIOS you are out of luck. Your best bet might be to contact the vendors tech support and see what they say.

After many hours of search I realized you were right ... Thanks. – Flame_Phoenix May 8 '13 at 1:40
Glad to be of help. Sorry the answer wasn't different. – Brad Patton May 8 '13 at 2:27

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.

Note that VT-d is not dependent on VT-x. That is, a VT-x enabled system can operate without VT-d, or without VT-d enabled or configured. You simply miss the benefits of the feature. Many people have asked about this point.… – A.D. Nov 6 '13 at 17:35
I don't think this answer is correct. Yes, VT-d is an enhancement to virtualisation, not a requirement. It basically allows VMs to gain access to certain host devices as though they were connected directly. I'm not sure how widely used this is. It is not required to run a VM under normal parameters. – underscore_d Sep 30 '15 at 15:11
