title: Change Hostname Vagrant
body: <p>I've setup two vagrant VMs of ubuntu - one for slave and one for master.I frequently get confused after logging into the vagrant VM using <strong>vagrant ssh</strong> which machine I'm in. What do I call this green string in the screenshot and how do I change this this for both slave and master machines like ubuntuslave and ubuntumaster?</p>
