The good news is that libvirt is working again (I must have done a 
git-pull in the middle of an update).  Thus, I am not seeing the large 
numbers of RTR-ADVERT.

Yes, I am seeing the new log message and I have a question about that.  
Every time a new virtual network interface is started, something must be 
doing some type of broadcast because all of the dnsmasq instances (the 
new one and all the "old" ones) suddenly wake up and issue a flurry of 
RA packets and related syslog messages.  To kick the flurry off, there 
one of the new "unsolicited" syslog messages from each dnsmasq instance.

Is this something you would expect?  Is this "normal?"  The libvirt 
folks they are not doing it.
