Hi Neelakantam,

I was just referring to running nova-network in a linux VM using the same
instructions as installing nova-network on a bare-metal linux server.  This
isn't very flexible though, and may not meet you needs depending on use
case (e.g., you can have different VMs being routers for different tenants).

In the Folsom-3 iteration, we will be working on an improved L3 model for
quantum that will be more flexible, enabling a model where all tenants use
a single linux device as their gateway, or a model where each tenant get
their own VM acting as a router (as well as other use cases).
