Why Intel Virtualization sucks today
-
AFAIK your OS has nothing to do with it.. Attempt at proof: Intel-VT is much newer than XP, so XP can not have explicit support for it, but it works anyway. According to Intel, E7600 supports VT. So I blame your BIOS (have you updated it?)

But can't the OS have new drivers? I've run Windows Update, and it's not picked up anything.

No, but the option is in there, and it's switched on. The OS just disagrees with it.

I've checked, and the BIOS has locked the virtualization support on. So I've ruled that out.

Thats weird. How do you know that the OS disagrees with it? Are you using a VM?
If everything was not true, would it be not true that everything is not true? So by saying everything is not true, you are automatically denying that everything is not true. Useful links:

I know the OS disagrees with it because the BIOS tells me that virtualization is enabled, while every program I know of tells me that virtualization isn't present

Oh yeah, I missed that bit the fist time I read your post, sorry. I don't have a clue whats going wrong with it, could it be a partly fault CPU?

I decided to go out and buy a new processor a few days ago, and went for the Core 2 Duo E7600. I was assured, and continue to be assured by the official processor specifications and my BIOS that I've got a processor capable of virtualization. It seems that somehow, I've managed to buy a processor which has my BIOS and OS disagreeing. According to the MS tool, Intel tool, Everest and CPU-Z, I haven't got virtualization. So far, I'm getting a little irritated. I paid about £100 for the processor, and the virtualization features were a major feature when I bought it. Does anybody know how I can make the OS agree with me?

Flash your BIOS if there's a newer version available and update your motherboard drivers. Just 'cause the BIOS says it's there and on doesn't mean it adheres to up-to-date standards. Cheers, Drew.

Have you gone into device manager and had it scan for new hardware (expand the computer node and see if it is even the correct class of device, and see if it needs it's driver sw updated)? I don't think XP will automatically detect the chip change...

The CPU, chipset (motherboard), and BIOS all have to support VT. The OS does not matter as long as the VMM will run in the host OS. According to: Intel® Core™2 Duo Processor E7600 "Intel® Virtualization Technology requires a computer system with a processor, chipset, BIOS, virtual machine monitor (VMM) and for some uses, certain platform software, enabled for it. Functionality, performance or other benefit will vary depending on hardware and software configurations." I have written several articles on the subject but the current marketing and specific technical information seems a little thin. I have had queries from readers about this too and I am trying to get some more information from Intel.

Thanks, I'm about to try that. I think I've got an interesting few days ahead of me.

what Drew said.
Personally, I love the idea that Raymond spends his nights posting bad regexs to mailing lists under the pseudonym of Jane Smith. He'd be like a super hero, only more nerdy and less useful. [Trevel]
