[Bug 956655] Re: libvirt dnsmasq causes runaway chain reaction

[Martin Pool]

mbp at joy% cat /var/run/nm-dns-dnsmasq.conf
server=10.0.3.1
server=192.168.178.1
server=10.0.3.1
server=192.168.178.1


I think this is an interaction between a few things that are themselves reasonable:

 - network-manager depends on dnsmasq, and makes it the default nameserver  in /etc/resolv.conf
 - lxc also sets up a dnsmasq for the guest, forwarding to the host 
 - lxc(?) inserts into dhclient.conf 
   ./dhcp/dhclient.conf:prepend domain-name-servers 10.0.3.1;
 - so the host ends up querying the guest, which loops back to the host

This might be just something in my own set up, and obviously I can avoid
it here, but it does look like it could bite others.
