[openstack-dev] [Network] Devstack+Quantum without namespaces

It appears that when I configure Devstack with Q_USE_NAMESPACES=False on a single-nic box, the resulting routing configuration is given two default routes (the original route and one added by quantum l3 agent for the floating ip range) and that prohibits external connectivity.  This addition happens as soon as the l3 agent is started, and the subsequent configuration of tempest will fail (due to a lack of external connectivity) where package installation is required.  Manually deleting the route added by quantum restores connectivity on the host, though private ip connectivity is lost. 

I apologize if I am missing something in the docs, but is there a way to reliably bring up devstack+quantum without namespaces?  Is a second nic required?  Note that this doesn't have to be production-grade (the docs are clear that running the l3 and dhcp agents on the same node is discouraged), as my goal here is only for a usable test environment.

Thanks in advance,
