[Xen-devel] PV Guest and PCI Passthrough, no more than 3.5GB Ram?
Hi everyone, I can''t seem to get PCI pass through to map devices outside of the 4GB memory range. I am booting Dom0 with iommu=pv and Domu with iommu=soft, is there some sort of setting change to make this work?

Let me start working on it today if nothing else preempts me. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
