Set your BIOS and Unraid to CSM/Legacy mode. Do not use the latest Radeon drivers. Use WHQL drivers. I used 22.11.2 and it did not work, performance was sluggish. I had to use 22.5.1 WHQL driver to solve that. A lot of errors in dealing with VM are solved when you realise that when you make changes to the VM template in the GUI all former changes you made in the XML template get discarded. As soon as you click the "Update" button in the GUI the current XML gets overwritten by a standard template and you have to edit your XML setting again. Also this may help you if you are using Unraid 6.11.5:

I got a little update on my progress with the VM. After days of testing and reverting back to Unraid 6.9.2 i finally got the VM working on Unraid 6.11.5. GPU passthrough is working flawless. The main issue i had was that i was running Unraid in UEFI mode. After setting my BIOS and Unraid to Legacy mode and selecting the WHQL driver instead the latest driver for the Vega card it worked. Now i have an issue passing through my Auzentech X-Fi Forte soundcard. It was detected in the VM and i installed the driver without issues. But i get no sound output. Here is the XML of my Windows 10 VM. I coloured the soundcard in green. Did i do something wrong? <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm'> <name>Windows 10</name> <uuid>53df5502-1f19-41b4-e561-840d802c9611</uuid> <metadata> <vmtemplate xmlns="unraid"

Hello Unraid Forum, i am quite new to Unraid and had a little pain setting up my server. Finally i worked things out and now i am running a Windows 10 VM with passed through soundcard and videocard. The VM boots just fine and the log ist almost error free. My big problem is the video card performance in the VM. I installed the latest AMD video driver 21.11.2 without issues, rebooted, everything seems to be working fine. Then i installed Firefox 102.5.0esr and then the problems began. Videos will be played back at a very slow framerate about 1 Frame every 5-10 seconds, sometimes even slower. This applies to all videos and sites. I found only one repeating error in the VM log and that was: 2022-12-05T11:10:11.884707Z qemu-system-x86_64: vfio: Cannot reset device 0000:0c:00.1, no available reset mechanism. 2022-12-05T11:10:12.952898Z qemu-system-x86_64: vfio: Cannot reset device 0000:0c:00.1, no available reset mechanism. I cannot get further with my knowledge and ask the forum for help, solving the slow video performance problem. My Hardware Specs: Mainboard: Gigabyte Aourus X470 Ultra Gaming CPU: Ryzen 9 3900X RAM: 2x16 GB DDR4-3200 + 2x8 GB DDR4-3200 Video Card: Asus ROG Strix Radeon Vega 56 Sound Card: Auzentech X-fi Forte 7.1 3900x-diagnostics-20221205-1223.zip
