I used virt-manager on Fedora to spin up the 5 needed Ubuntu 14.04
hosts, then set up the ssh keys to start playing with ansible on the
control host.
The bin/hosts script uses the virsh command to generate the list
of hosts in /etc/hosts format (so you can simply append it to the
hosts file in your control host).
