Before we get sidetracked too far into the OVS vs. Linux Bridge bikeshed,
let's reflect on the fact that DVR is *not* enabled by default in
DevStack. Nor is nova-network's multi_host enabled by default.

So in all cases, someone looking at the innards of Nova-Network or
Neutron or looking to create a "production-like" DevStack 
will be consulting documentation for configuration details.
