[idata]

Hi.

Does this chip support I/O Virtualization?

Have some one here using this feature with this chip?

Im using Xen.

Thanks!!!

According to the following website, this processor support only (VT-x) but not (VT-d).

Just a update.

There is been a lot of forums that say that chip manufactures don't update their docs about what features their products have.

I speak by chat with a technical guy from Intel about this same question:

Do this chip support vt-d?, he check the same web page u point me Adolfo_Intel(appreciated your time for aswering) and the say answer "No".

Well, reading xen maillist I found same person saying that he have some 5600 chips with vt-d enable.

Them I decide to enable and see what happen:

I just need to verify if this works, but this is good news, I had read other forums and people with this same message:

(XEN) Intel VT-d DMA Passthrough not supported.

And they could pass some devices to ther HVM, I will give more details once I test my win2k3 machine.

Thanks!!!

Hi I had back.

Sucessfully could pass my USB port to my HVM running windows xp pro, the same behaviour as other MoBo, It just support USB 1.1, but for what I need is good.

MoBo: SuperServer 5026T-TB

U had to enable the vt-d optio into the BIOS, xen 3.4.3 from gitco, u have to enable the kernel before:

kernel /xen.gz-3.4.3 dom0_max_vcpus=2 dom0_vcpus_pin dom0_mem=1024MB iommu=1

I would try windows 2k3 and win 7 and let u know.

Again, lack of info from Intel, see u!!!
