This document provides information about using OpenNebula's oneprovision tool to provision clusters in a cloud environment. It includes an example of a provision template that specifies details like the driver, project, OS, and networking. It outlines commands for creating and managing provisioned clusters, hosts, datastores and networks. These include listing, deleting, power control and SSH access for hosts. The goal is to demonstrate how to provision resources and hosts on demand using OpenNebula.
