I think an administrator on OS "X" is already familiar with the firewall capabilities on his/her OS and so having a new, less-capable abstraction instead of the firewall s/he already knows is not a benefit. If these were instead hooks in libvirt that called sample scripts per-OS, administrators could easily do whatever they want to do when an interface is brought up, brought down, or migrated. They could then also make full use of their firewall capabilities and customize completely as needed.
