Recently I updated my arch linux machine and now passthrough is not working.
I've read these archives all the way back this thread, to no avail: https://www.redhat.com/archives/vfio-users/2017-August/msg00021.html Did a complete arch reinstall and got the code 10. Have done a complete fresh clean install of Fedora 27, enabled IOMMU/vfio-pci and all seems valid, but I still am getting code 10 in windows 7 for my NVIDIA gpu. I've compared my xml to archived copies of the same VM xml and they are exact. I'm starting over and have noticed if I add in the hyperv features it crashes windows. My current xml is at the bottom. Please help! If there is more info needed please ask and I will provide it.
