Oracle VM

■Oracle VM Server: A self-contained virtualization environment designed to provide a lightweight, secure, server-based platform for running virtual machines. Oracle VM Server is based upon an updated version of the underlying Xen hypervisor technology, and includes Oracle VM Agent.

■Oracle VM Agent: Installed with Oracle VM Server. It communicates with Oracle VM Manager for management of virtual machines.

Figure 1–1, "Oracle VM Architecture" shows the components of Oracle VM.
