The Flowvisor service is responsible for slicing the network, therefore, guaranteeing the isolation of the experimentation.

Installation

Setting up a Virtual Machine

1. Generate a new Xen VM and access its console. (TEST)

Login with the root user

To create the virtual machine which will host the flowvisor, run in your terminal the commands below. Pay attention to substitute the "XXX" for your Island ID and the "YYYY" for your Institution acronym.

The first command will create the virtual machine and the second one will start up the VM and login in console mode.

We will use the Flowvisor version 0.8 for this tutorial.
