Cannot add network devices using PCI Passthrough from QEMU hypervisor
0%
Description
When running pfSense as a VM in QEMU you are unable to use PCIe passthrough of network devices.
For example, you cannot pass through a PCIe Wireless card to pfSense to create a Wifi Access point. Nor can you dedicate NICs to pfSense - you have to create a bridge.
This problem is caused by a bug in freeBSD (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=243640)
The fix is to make sure you pick up the latest kernel once freeBSD implement it.
Steps to reproduce
Install pfSense in Proxmox
Configure PCIe passthrough per instructions here: https://pve.proxmox.com/wiki/PCI_Passthrough
Update ID.conf in /etc/pve/qemu-server with:
hostpci0: 03:00,pcie=1,rombar=0
machine: q35
(Note the PCIe device ID will be different. Get that from lspci)

Update to details above:
Passing through the PCIe-based WiFi is necessary for a proxmox hypervisor because proxmox deliberately does not support wifi NICs due to issues with bridge networks.

There is nothing actionable for us here. It's a problem in FreeBSD that must be addressed upstream.

We can't keep open duplicate entries for everything in the FreeBSD PR system, even if they might be relevant to certain people.
Note that I set this to "Needs Patch" that while it is a closed state, also indicates that it isn't rejected, but must be solved via outside/upstream action.
