Actually no, I don't think so, I think I use the nova-network.

The documentation http://docs.openstack.org/havana/install-guide/install/apt/content/ says:

Configuring Networking can be one of the most bewildering experiences you will 
encounter when working with OpenStack. To assist in this we have chosen the 
simplest production-ready configuration for this guide: the legacy networking 
in OpenStack Compute, with a flat network, that takes care of DHCP.

This setup uses "multi-host" functionality: the networking is configured to be 
highly available by splitting networking functionality across multiple hosts. 
As a result, there is no single network controller that acts as a single point 
of failure. Because each compute node is configured for networking in this 
setup, no additional networking configuration is required on the controller.

(Chapter 5: Enabling Networking)

and I have installed the nova-network package.

I've downloaded my entire /etc to http://xgm.de/upload/etc/ if you or anyone 
else wants to have a look! Yes, these "123" are the actual passwords, it's 
just from a VM on my local computer.  ;-)

Thanks a lot!

Florian
