To pass through IGD to guest, user need to add following lines in Xen config file: gfx_passthru=1 pci=['00:02.0@2'] Besides, since Xen + Qemu upstream is requiring seabios, user also need to recompile seabios with CONFIG_OPTIONROMS_DEPLOYED=y to allow IGD pass through successfully: 1. change CONFIG_OPTIONROMS_DEPLOYED=y in file: xen/tools/firmware/seabios-config 2. recompile the tools I have successfully boot Win 7 and RHEL6u4 guests with IGD assigned in Haswell desktop with Latest Xen + Qemu upstream.
