I tried changing my default network to remove the <dhcp> section, 
restarted the network, and rebooted a guest to try and acquire an 
address from DHCP - it failed. 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 think 
it's possible that dnsmasq sometimes isn't terminated if libvirtd crashes)
