Can you do "ps -AlF | grep dnsmasq" at a > time when you see this behavior, and send that. Perhaps there was > another dnsmasq hanging around listening on that interface?

I sometimes suspect dnsmasq doesn't get restarted at all, although libvirtd/network does. Another "workaround" seems to be eg. range 192.168.1.0/24; 192.168.1.1/24 at interface; leases 192.168.1.1-192.168.1.1. This is from ISC DHCPd where you have to provide leases for pool with static (IP:MAC) hosts. Thanks, Zdenek
