I used fc20 and built the libvirt rpms from source. libvirt-guests was 
not running when updating from 2.2.0 to libvirt 2.3.0. I switched 
systems and retried on fc23 after rebuilding libvirt 2.2.0 and 2.3.0 
from source. On this system I cannot reproduce the behaviour.
You are correct that the behaviour I got does not match with the 
requires directive. So my guess is that my old fc20 might still have 
some systemd problem which has been fixed in newer fc versions.
