Hi everyone,
I am trying to pass through a PCIe USB card to my VM, and I am following Spaceinvader One's guide, which is super helpful. The problem now is I can't split the PCIe USB card to its own IOMMU group, and checkbox in front of it is gray out so I can't bind vfio at boot.
What I have tried so far:
+ In the VM setting, I tried all three PCIe ACS override modes (downstream, multi-function, both), and none of the modes will split my PCIe USB card to its own IOMMU group.
+ I try all different available PCIe slot on my motherboard, all the same thing.
+ The card itself is good. If I plug a mouse receiver/USB disk into my PCIe card, the unraid will pick up correctly.
