OK, I am going to slightly increase the scope of this. Simon, how
receptive are you to adding a "couple" of new options to enable/disable
some logging.
1. log-ra to enable RA logging which, by default, is disabled. This
would be its own option and not related to log-dhcp.
2. log-dhcp-renew to enable the log messages about renewing DHCP
requests which would, by default, be disabled.
The messages from both of these currently run as if they were disabled.
Since I am running/testing using dnsmasq's RA services, I first noticed
all of the RA related messages and would like them to be normally
suppressed.
Apparently other libvirt users noticed the dhcp-renew messages and don't
wish to see them either.
If you are receptive, I will do the heavy lifting but I would like to
see this in 2.64 if there is possibly enough time.
