Dual NIC passthrough

[vobo70]

Hello,
I have Asrock J4105M mobo with proxmox 5.3 and Intel dual network card which I would like to pass to pfSense.

04:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (rev ff)
04:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (rev ff)

When I pass second port everything works, but first will not work (and both ports too),
VM does not start and I have got this error in proxmox dmesg:

[ 7092.974659] vfio-pci 0000:04:00.0: enabling device (0000 -> 0003)

you can try just pass 04:00 to pfsense VM

Thank for you answer;
but unfortunately when I pass 04:00 the pfSense cannot find any network interfaces ...
(it should work as it works when I pass second port only)

Hi guys, not sure if you've fixed this yet but I experienced this exact same issue with a dual NIC Intel card on Q35 with pcie=1 enabled.

The fix for me was to swap the order of the ports in the hostpci values. I added the second port as hostpci0 and the first port as hostpci1. Nothing else worked until I did this and it magically detected both ports. Really weird stuff.
