dhcp-agent network namespace does not have a default route, can't use
upstream dns
Status in OpenStack Neutron (virtual network service):
Fix Released
Status in neutron grizzly series:

Bug description:
The network namespace that dnsmasq runs in does not have a default
route on creation (to the router for that network) and as such trying
to use an upstream nameserver fails.

I have added the default route on only 1 of the namespaces, the
10.0.129.0/24 one but all others do not have them and can therefore
not resolve their upstream servers.
