theone Posted March 6, 2021 Share Posted March 6, 2021 (edited) I am trying to passthrough an NVIDIA GPU by choosing it in the VM setup page s but get ERROR when starting the VM: internal error: qemu unexpectedly closed the monitor: 2021-03-06T13:18:27.827439Z qemu-system-x86_64: -device vfio-pci,host=0000:01:00.0,id=hostdev0,x-vga=on,bus=pci.4,addr=0x0,romfile=/mnt/disk3/Documents/Installed Utilities/Hardware Drivers/Computer - unRaid/HP.Quadro2000.1024.111018.rom: vfio 0000:01:00.0: group 1 is not viable Please ensure all devices within the iommu_group are bound to their vfio bus driver.

Try to pass the audio part too: [10de:0be9] 01:00.1 Audio device: NVIDIA Corporation GF106 High Definition Audio Controller (rev a1) Try enable acs override (pcie_acs_override=downstream or pcie_acs_override=downstream,multifunction). Try to move the gpu into a different slot. Edited March 6, 2021 by ghost82 Quote Link to comment
theone Posted March 6, 2021 Author Share Posted March 6, 2021 I did try passing through the audio as well didn't help. Are there any possible side effects for overriding ACS? My motherboard is x10sll and I have the 8 port sata on the other slot so I cannot move the gpu to any other slot. Quote Link to comment

theone Posted March 6, 2021 Author Share Posted March 6, 2021 should I start with downstream and if not then try the other options - multifunction or both? or it doesn't matter? Quote Link to comment
