The point of the impl quoted above is

 - The use of Dnsmasq is a private implementation detail that must remain
   hidden from applications using libvirt, so an alternate DNS/DHCP
   impl can we switched in without breaking apps using it
 - It provides applications a programmatic API for controlling the
   address assignment, because you cannot assume login access to
   the OS running dnsmasq.
 - It ensures the configuration of the network is fully specified in
   a single place, so can be guarenteed identical across all machines
   using the same XML configuraiton.

For all these reasons, we explicitly do not use a configuration file with
dnsmasq - indeed we explicitly disable it, and do not intend to support
its use.
