Hello! I am trying to install a ubuntu VM running HiveOS (a mining software, not really important) with a GTX 1050 Mobile GPU passthrough and it seems to be failing. When I try to start the VM (here is the XML: https://pastebin.com/RKXkyuzDz ) it says internal error: Unknown PCI header type '127' for device '0000:01:00.0' and fails to start. PCIe override is set to both. In system devices it lists my GPU as this ( https://pastebin.com/Wgt6hqjj ) and the GPU is set to bind to vfio at boot and its in its own IOMMU group. My syslinux.cfg entry that I boot from is https://pastebin.com/t163kQ4T . I could not get GPU passthrough to work on proxmox either. Sometimes I can get it to not have that error but then the server display freezes up and I Cant access the webui anymore. I do have a iGPU inside the server that is set as the primary GPU it says when loading in. Here is my system log https://pastebin.com/DwqJ48sF . I have tried multiple vBIOS for my card and I have this problem every time. I have also had this error https://pastebin.com/CHkQf2b7 . I belive the problem may be that its switching between the iGPU and dGPU so when it freezes up its because it turned off the iGPU to use the dGPU hence why the UI freezes but I'm not sure because I cant figure out how to disable that feature in the bios as its Asus and EXTREMLY restricted. Any idea why I cant get GPU passthrough to work? Other people seem to have gotten it to work but a ton of other people are having issues it seems aswell. Thanks!

I have also tried to blacklist the nvidia, nouveu, and radeon drivers in the blacklist.conf.
