A long time ago I was annoyed by all the logging produced by dnsmasq and searched the standard/sample dnsmasq.conf for an option to reduce the logging, but all I saw were options to *increase* it! I guess I didn't look far enough. It would be nice for libvirt to take advantage of this, but since the logging levels of other parts of libvirt are handled in libvirtd.conf and qemu.conf, maybe it would be better to add the option there rather than making it a part of the config for each network. (on the other hand, it might be nice to be able to have more verbose logs for some networks than for others). Does anyone have an opinion about this? Maybe we could have a "dhcp_quiet" option in libvirtd.conf? (alternately I guess we could a <log> element to networks, but that would require something sufficiently generic that it would also be useful if someone decided to, e.g., write a network driver that used the ISC dhcpd instead of dnsmasq).
