11) Enable VNC Proxy

1. /etc/init.d/vncap restart

Note: There are a few networking issues within virtualbox:

You must restart the proxy after every connection/disconnect for it to accept additional connections.
VNC only works with Chrome, there is a bug preventing the virtualbox network from working with firefox.

The VNC Proxy is a gateway into your backend infrastructure. It allows secure connections, without user interaction.
