Remember, when you added a FlexiScale Server to a deployment nothing was actually created. If you want FlexiScale to actually "build" a server, you must first click the Provision link under Actions.

Confirm that you want to provision a server and click the Provision button.
You see the state of the server change from "unprovisioned" to "stopped." At this point, FlexiScale is provisioning the necessary hardware resources to support your server when it is launched.
At this point no server has been launched.
