July 30, 20223 yr I had everything working fine for years then I had an issue which required starting over and now I'm really struggling to get a Windows 10 VM to work. Any help and I'd be greatly appreciative. The first time I did this I remember having to do a bunch of stuff manually but my impression is that now all the settings can be done through the VM configuration and I have posted the XML that gets generated below.. The two issues I am having is that 1) The GPU passthrough video but Windows does not recognize that the graphics card is there so I am stuck at 800x600 originally with the Microsoft Generic video option but after updating Windows with the GPU listed but with a warning triangle in Device Manager and still limited to 800*600. It says Windows has stopped this devices because of problems with an error code 43 2) None of the PCI cards show up. I have two USB controllers and a sound card and none of these show up as items I can configure from the GUI. I had previously stubbed one of the USB controllers and possibly the GFX card but I deleted that line from the config as my understanding is that is no longer how it is done. I have tried with and without a GPU BIOS -- the GPU BIOS file is downloaded and edited as per the SpaceInvader video on that topic. <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm' id='23'>

July 31, 20223 yr Author Someone sent me this on and it solved the problem. For me it was #8 but this is a useful post so deserves a link in case anyone else has issues https://mediaserver8.blogspot.com/2020/07/problems-passing-through-gpu-to-unraid.html Edited July 31, 20223 yr by Naldinho
