Hi all,
Can anything be done to resolve the below?
I've purchased a couple of USB3 PCIe cards in the hopes of passing them thru to a couple of VM's, however they landed in an IOMMU group with other devices.
I've tried all empty PCIe slots, same result, they land in group 14. I did stub out 1106:3483, to the extent I get the choice to pass-thru a card to a VM, however the power on throws this exception:
"qemu-system-x86_64: -device vfio-pci,host=06:00.0,id=hostdev0,bus=pci.0,addr=0x8: vfio 0000:06:00.0: group 14 is not viable Please ensure all devices within the iommu_group are bound to their vfio bus driver."
Group details:
IOMMU group 14:

Is this a dead end?
