title: How to simulate a SDN network using VMs (Virtual Box)?
body: <p>I am trying to simulate a SDN network using VMs as hosts (Virtual Box). Any ideas?</p>
  
  <p>An example: Two VMs running Ubuntu Server and One VM running an Open vSwitch and a controller</p>
  
  <p>The examples that I already found are people using Mininet (but the virtual hosts are too basic for my experiment). I also tried to attach an external host to the Mininet but I think that I made some wrong configuration because the ARP requests do not reach the hosts.</p>
  
  <p>Thank you guys!</p>
