The DeltaCloud driver for OpenNebula is an implementation based on the OGF OCCI API for the DeltaCloud Framework that RedHat is developing.

When using the driver for OpenNebula, the credentials passed in response to the HTTP 401 authentication challenge should be your OpenNebula user and password.

The address, in which the OCCI server is listening, needs to be defined in an environment variable called OCCI_URL.

The Flavor parameters such as memory, cpu, storage, even the network configuration, can be defined in the OCCI templates that OpenNebula offers. In this way, each administrator can set the configuration that better fills his requirements.
