Hello, I''ve previously been successful with Xen4 and VT-d on other systems. I am having trouble getting VT-d passthrough working to a WinXP domain with DX58SO (Q45) motherboard and i7 930 CPU. VT-d is enabled in bios, xm info shows hvm_directio capability, I have iommu=1 set, I have the devices bound to pciback on dom0 cmdline, xm pci-list-assignable-devices shows the devices as

Hello, I''m having problems with VTD on this board. The board/cpu/bios all support vt-d and I think maybe I''m just missing something? Any feedback would be much appreciated :) Output below: root@vm:~# xm create /etc/xen/vm-nine.cfg Using config file "/etc/xen/vm-nine.cfg". Error: Failed to assign device to IOMMU (0000:05:00.0@100,msitranslate=1,power_mgmt=0)
