Interesting. That should have been installed as a dependency. I'll look into why it's missing. Was your test platform F28, or something else?

For the sake of gathering information, I'll build with this patch applied and try it to see if libvirt's functionality is still there (what's supposed to happen is that libvirt will monitor all DHCP traffic, and grab the IP address of the guest out of the DHCP response, then use that IP to build additional iptables rules).
