NIC Passthrough for pfSense VM

Recommended Posts

Hello all,


I'm trying to create a pfSense VM on one of my Unraid boxes, but I can't get passing through the NIC to work.


Error message:

internal error: qemu unexpectedly closed the monitor: qxl_send_events: spice-server bug: guest stopped, ignoring 2023-07-02T19:10:29.604731Z qemu-system-x86_64: -device {"driver":"vfio-pci","host":"0000:11:00.0","id":"hostdev0","bus":"pci.1","addr":"0x0"}: vfio 0000:11:00.0: failed to setup container for group 40: Failed to set iommu for container: Operation not permitted


System Devices:



I've tried this with PCIe ACS override disabled, downstream, multi-function, and both; same error every time.



Please let me know what other information is needed to figure this out. Thanks.
