Looking at that link, I see the board on the Intel *VT* list, NOT the *VT with Directed I/O* (aka, VT-d) list. The VT list is presumably referring just to VT-x (virtualization extensions), and they are not being listed as supporting VT-d (IOMMU).

I can't speak much about the motherboard stuff, but for the processor, if you're going Intel, ark.intel.com will tell you if a processor supports VT-d or not.

Processor support alone is not enough for VT-d. VT-d must be also supported and enabled on the chipset (and therefore, the mainboard BIOS/EFI).

It's sometimes hard to find resources if a mainboard really has a working IOMMU, that's why the list in the Xen Wiki is usually very valuable.

Hi list,

I´m planning to buy a new machine and I´ll need to have pci
passthrough working on it.

AFAIK, pci passthrough to paravirtual Linux guests would also be possible without hardware support.

Looking at Xen wiki (http://wiki.xen.org/wiki/VTdHowTo) there are
some recommended chipsets and motherboards but the list is little
outdated, I can´t find those hardware anymore.

I´m looking at Intel DZ68DB MotherBoard (Z68 chipset,
http://www.intel.com/support/motherboards/desktop/sb/cs-030922.htm)
that intel´s website claim to have vt-d support. Someone has Xen PCI
Passthrough working on this board/chipset model ?

I would like to know from the list some working PCI Passthrough
configuration with new hardware.

Best Regards,
Alexandre

Best Regards,
Felix
