3.6 Deploying Oracle VM Agent

You can use Oracle VM Manager to configure the deployment of Oracle VM Agent. See the Oracle VM Manager User’s Guide for information on configuring Oracle VM Agent with Oracle VM Manager.

3.7 Oracle VM Agent API

An application programming interface (API) is available for Oracle VM Agent. You can use the Oracle VM Agent API to perform a number of actions on guests and on the Oracle VM Server. The Oracle VM Agent API uses the XML-RPC protocol. To see a list of the XML-RPC functions available, enter the following URL in a web browser:

https://hostname:8899/

The hostname refers to an Oracle VM Server. A list of methods and parameters are displayed.

See the XML-RPC protocol specification for more information on how to use

XML-RPC.

The following sections give examples of common Oracle VM Agent API functions. The examples are not extensive, but serve to give you an idea of how to use the API.
