Motherboard H57M-USB3 support VT-d (virtualization I/O)? - fake virtualization?

[zygert]

I have H57M-USB3 with Intel Core i5 650 and in my debian with XEN 4.0 whey I type "xm dmesg" I have seen:
"(XEN) I/O virtualisation disabled"
why?

I bought this set because in specyfication Intel Core i5 650 support:
* Intel® Virtualization Technology (VT-x)
* Intel® Virtualization Technology for Directed I/O (VT-d)
and motherboard H57M-USB3 in bios have enabled
* Virtualization Technology

All should support full virtualizatio, but didn't.
Chipset H57 also support Virtualization in INTEL's specyfication. But product of Intel BD82H57 PCH (chipset H57) don't support V. only BD82Q57 (chipset Q57) PCH support VT-x and VT-d. I afraid that H57 don't support VT-d because INTEL enable this function in our product if this true.

My quastion is:
What Gigabyte mean enabled Virtualization Technology? This is full virtualization VT-x and VT-d or only VT-x.
May by Gigabyte GAQ57M-S2H full suport this technology, but in bios I saw the same options that can I see i my motherboard H57M-USB3.

Please help, Gigabyte what is truth? This is fake in Gigabyte products?

I am afraid that I really can't help you with this one. I would suggest that you query this with GGTS and see what they say. You could try PMing runn3R(moderator) also, he might know.

I found the solution this problem - sold H57 .

OK, but trully is:
Motherboards:
H57M-USB3 don't support VT-d (virtualization I/O)
GA-Q57M-S2H support VT-d (on technical specyfication - didn't test this)

Intel DQ57TM supprot VT-d (test OK)

As you say if the board doesn't support it then you don't have a chance. Just another case of a bit more investigation before purchase would have save a lot of trouble.
