4. open mano set up and usage

•
•

The document provides information on installing and using openMANO, an open source platform for network functions virtualization management and orchestration. It describes: 1. The requirements to run openMANO including compute nodes, storage, and OpenFlow controller. 2. The different modes openMANO can run in including normal, host-only, development, and test modes. 3. How to install openMANO either automatically through scripts or manually by downloading packages and configuring components.
