What error are you getting in the Windows device manager? If you're getting error 43, you have to mask your hypervisor either by disabling the hypervclock (check part 4 on aw's guide <http://vfio.blogspot.ca/2015/05/vfio-gpu-how-to-series-part-4-our-first.html>) or by spoofing your hv_vendor_id (as explained here <https://www.reddit.com/r/VFIO/comments/479xnx/guests_with_nvidia_gpus_can_enable_hyperv/>). The former can have a pretty noticeable impact on your performance, though, so you'll probably want to go with the second option if you're ok with using a nightly build of qemu.
