However, I have noticed one thing. Simon Kelley had me add a little "instrumentation" to dnsmasq trying to pursue this large number of RTR-ADVERT messages. I am going to do a little more instrumentation.
What I have noticed is that there seems to be a broadcast of something whenever a network is started so that all dnsmasq instances (one per started network) go into "flurry" mode with issuing RA packets and syslog messages.
Does anyone know if something in libvirt is doing that?
libvirt itself doesn't do anything directly that would cause that; I'm guessing it's a side effect of creating the bridge, or adding an IP address - perhaps either the bridge module or the IP stack is sending around some sort of notification that the topology has changed.
