Some answers inline. > If I "disable" the device on the kernel line with pciback.hide=(04:01.0), > this seems to work according to logging. However the device is still visible > with lspci in Dom0. Is this normal ? yes, that is normal > I am still not 100% convinced that my motherboard is VT-D compatible (BIOS > ?) However if I read other posts , the output of > '/sys/hypervisor/properties/capabilities' and '/proc/cpuinfo' should ensure > that the system is VT-D capable. Latest BIOS is installed. > Is there any tool to 'proof' my system is VT-D capable ? There are BIOS options that you may need to turn on if you haven't already. the ouput of 'xm dmesg' should have a like IOMMU enabled > Any suggestions are welcome ! Once you see the IOMMU enabled, you can run: xm pci-list-assignable-devices to see the devices that you can pass through. like others have suggested, make sure you follow http://wiki.xensource.com/xenwiki/VTdHowTo You may want to install a newer version of Xen, such as Xen 3.3.1 when it releases or simply run xen unstable or testing.
