Hi!

IOMMU should be enable in the BIOS. Double check that 🙂

Also please share your grub config to see if it's correctly written.

After playing with it more, the issue appears to be passing multiple devices of the same type. In this case RADEON WX7100. If I take it down to one card it works as expected. If I add more than 1, pick any quantity, then I run into the issue.

The issue goes away once I reboot the host, and then I can assign a card, but the second the VM reboots the error comes back
