We also hope that using onos.py will make ONOS development easier and more fun.

Configuring your development VM (or server)

This document assumes that you already have a VM or server  (we recommend Ubuntu 16 LTS) where you can compile ONOS, preferably using buck (or possibly with Maven - see below.)

ONOS java processes tend to consume a huge amount of memory. In order to run an ONOS cluster in a single VM, you should allocate a large amount of RAM to that VM. We recommend 2-4 GB (or more if you have it) for each ONOS node that you intend to run. You can see how much memory and CPU ONOS's java processes are using by running top - if you start using swap space, the performance of ONOS and Mininet will suffer greatly!

Next, use Mininet and onos.py to start up a virtual ONOS cluster and data network:
