Proxmox-VE 7.x: Enable PCI passthrough for I226-V Ethernet network devices, with non-passthrough exceptions for specific ports (tested with CWWK's CW-MBX-AD12 2.5Gbps 6-port mini-PC).

Some notes:

  • Disable Above 4G in BIOS, otherwise vfio-pci (on the host) will panic all the time when turning off the Opnsense VM, and the only way to get off the problem is to hard-reset the host entirely.
  • On Opnsense Guest, go to the Web GUI, option System -> Settings -> Tunables, click "Add", and add the virtio_console_load=YES config Make sure QEMU Guest Agent is disabled.

Various slow-ish portable Shell utilities for JSON values (all depending on `jq`)
#!/bin/sh
##
# Sets properties in a JSON object.
#
# Properties are given in the format `KEY[:TYPE]=VALUE`, as a var-arg argument to the function.
# `TYPE` is optional; if not provided, the value will be simply serialized to string, regardless
# of its format. But if a type is informed, some conversion and validation occurs prior to
# assignment. Type names are case insensitive. Accepted types:
