Re: [Xen-devel] Xen VGA graphics passthru wiki page

Hi Sergey and Pasi,

AMD RD-890 series chipset should be the first desktop chipsets to support an 
IOMMU,
if and which server chipsets also support it i don't know.

Good to know it seems to work ok, was considering to purchase that platform as 
well.

Sergey, what specific brand/type mobo do you use ?
