 In order to successfully run Mirantis OpenStack under VirtualBox, you need to:
 - download the official release (.iso) and place it under 'iso/' directory
-- run "./launch.sh" (or "./launch\_4GB.sh", "./launch\_8GB.sh" or "./launch\_16GB.sh" according to your system resources). It will automatically pick up the iso and spin up master node and slave nodes

 If there are any errors, the script will report them and abort.
