I want the network to start automatically with libvirtd but "without" dnsmasq. I 
haven't say anything about starting it with net-start. I've just put those two 
commands to show you that merely starting the netwrok "causes" dnsmasq to start 
too, hence I had talked about the thing being hardcoded.
