Hanging dnsmasq was either the case or it has been fixed in 0.8.4. 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,
