i have a clean install as of today and wanted to pass through my GTX 1660Ti to my VM, ive noticed that it is sharing one group, i remember in an older version of Unraid i was able to find a option in the settings that i could move the GPU tp its own group, but im not longer able to find this, ive attached the immou group below

Settings, VM Manager, PCIe ACS override

Enable ACS override

 

yeah now im having the issue with this error.

 

internal error: qemu unexpectedly closed the monitor: 2019-06-08T18:18:28.170773Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,id=hostdev0,bus=pci.0,addr=0x3: vfio 0000:01:00.0: group 14 is not viable Please ensure all devices within the iommu_group are bound to their vfio bus driver.

 

i know the 1660Ti is a bit weird and has its own USB bus controller 

 

 

IOMMU group 14:[10de:2182] 01:00.0 VGA compatible controller: NVIDIA Corporation TU116 [GeForce GTX 1660 Ti] (rev a1)

[10de:1aeb] 01:00.1 Audio device: NVIDIA Corporation Device 1aeb (rev a1)

[10de:1aec] 01:00.2 USB controller: NVIDIA Corporation Device 1aec (rev a1)

[10de:1aed] 01:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1aed (rev a1)

 

i just want the one VM to work with this card. Space Invaders video is no help at this point because the 1660ti is the only card i know with this usb controller.

 

Did you pass through all devices in group 14 to the VM
