Currently the Quickstart page on kylo.io describes the process for using the downloadable virtual machine as:
Download Kylo Sandbox for VirtualBox
In VirtualBox: File | Import Appliance
Start VM and allow up to 10 minutes to start services
From web browser: Kylo Ops Manager | Kylo Feed Manager
Application login: dladmin/thinkbig, Sandbox OS login: root/kylo
Step 3 is incorrect, or at least misleading - the services within the virtual machine have to be manually started via Ambari.
