Works flawlessly. Linux works fine with the igd assigned as primary (pc machine type and igd using slot 2). Linux doesn't work in UPT mode for me. That is more a guest driver issue though. The i915 driver of older kernels Oopses. The i915 driver of recent kernels (4.4.5+) loads fine on q35, but fails to drive my monitor, no matter whenever I enable the opregion or not. For pc an additional kernel patch is needed (which hopefully lands upstream soon) to reach feature parity (as-in: no Oops on load) with q35. For windows UPT mode is the only thing supported by the drivers. Needs the opregion enabled to show something on the connected display. Works fine on both pc and q35, in parallel with a emulated display, and you can configure things as you want (mirror, expand desktop, use only one of the displays).
