You need to use your VBIOS. Run the ubuntu from flash drive(without install) install gcc and export your own bios. Bios from another GPU gives you this driver issue.

Post your XML VM settings and Tools->System Devices(what iommu you use), also check that iommu enabled in the bios settings. Check that you properly passthrough the GPU(bios/audio device with multifunction)

https://forums.unraid.net/topic/136621-unraid-plugin-for-igpu-sr-iov-support/ This works for intel integrated GPU or nvidia, so you can use it in multiple VM/docker containers

You can do it with the script, so when you start the VM you stop the docker container, unload drivers and disable GPU in the system, then passthrough it to VM, but simultaneously I'm not so sure. Another variant is some USB GPU(external case, or just usb tiny usb gpu for docker and iGPU(or if you have dedicated) for VM).

Just did absolutely the same. Getting vbios, then just select the gpu and hdmi audio to fvio via UI(you don't need to follow instructions with manual edit modules/grub/etc...), then I modified the /boot/syslinux/syslinux.cfg. I added: append initrd=/bzroot earlymodules=vfio-pci video=efifb:off,vesafb:off gfxpayload=text This line disables the GPU in Unraid, so I can successfully use it in VM(image will freeze after boot menu until you run a VM which is ok, so we don't use the monitor for unraid). Then just edit VM setting in xml format and add the rom file for audio. To install amd drivers correctly you should enable mutlifunction='on' to the gpu and set audio and gpu to the same bus and slot and use function=0x1 for audio, then you can install official drivers with adrenaline package. Then run. I have also a problem with GPU reset, but there is a fix for that: https://oomza.cutegay.software/inga-lovinde/RadeonResetBugFix/releases Also, VM freezes sometime, so I still investigate why does it fail(1 cpu core is 100% loaded and vm doesn't start, but all is ok in logs).

I was able to passthrough iGPU on my minisforum um790 pro with Ryzen 7940hs and 780m graphics. Just follow the instruction https://github.com/isc30/UM773-Lite-Proxmox To get the VBIOS from your gpu use vbios.c (I just run ubuntu from flash drive with "Try Ubuntu" option. Install GCC and extract the bios) For passthrough to Windows 10 guest just install it with the "Sea Bios" param from the beginning and add the rom file. If you want to passthrough to Windows 11 guest you also need to extract AMDGopDriver and use it for audio device. (I extracted it from the official bios bin file with UBU tool and then converted to the rom format with the edk2 -> EfiRom.exe)
