March 3, 20233 yr Hello everyone. I have a problem with the "GPU Passthrough". Previously I had an Gigabyte motherboard and I had no problem but I upgraded to an MSI motherboard with 2 PCIE 4Gen. Since my change I am no longer able to do GPU/PCIE PASSTHROUGH. I currently have an MSI MPG X570S EDGE MAX WIFI motherboard (MS-7D53) Error: ( qemu-system-x86_64: vfio: Cannot reset device 0000:2d:00.1, depends on group 35 which is not owned. ) Do I need to change the motherboard or is there something I can do in the bios/unraid options? (French to english with google)

When selecting the devices in the VM you need to have all parts. so for my 2060 I would need to select the GPU 82:00.1 the audio and the other two pci devices .2 & .3 even thou there is not a usable Usb/serial ports on the card. attach the full diags file as Squid requested.
