I would like to set up a Linux machine, being able to run Windows via Xen in parallel to play some games. According to http://wiki.xensource.com/xenwiki/XenFaq 7.3 the usage of 3D graphics in DomU is not possible. But point 3 of section 7.3 says that IOMMU would enable this feature. Since VT-d is Intel's equivalent to IOMMU, I would like to buy a mainboard supporting this technology.
Now it is hard to point out which chipsets support VT-d. The appropriate VT-d doc of Xen ( http://lxr.xensource.com/lxr/source/docs/misc/vtd.txt ) only references some sample mainboards and machines, these only seem to be such with Q35 chipset / vPro.
A vmware presentation ( http://communities.vmware.com/servlet/JiveServlet/download/702997-1574/N... Slide 15) says, that Seaburg and Bearlake chipsets would support VT-d - but Bearlake would not only include Q35, but also P35, X38, ...
So please could someone lighten up this a bit?
