Oracle VM

Oracle VM is a platform, and its various components are discussed briefly in the subsequent sections. As we work through the rest of the book, we will install and configure these components.

Oracle VM Manager

Oracle VM Manager is installed on a physical machine which is eventually used to manage the Oracle VM Server pools. This is the WebUI interface, developed with Oracle's ADF. We will be using it to manage our Oracle VM platform. So this management console, which we can access in the cloud, is essentially the interface we will use to administer our Oracle VM platform for tasks such as:

• Creating VMs from media, template, and other resources

• Importing and exporting ISO files

• Performing live migration

• Creating and managing VMs and VM templates

• Creating and managing (shared) storage

• Other admin tasks such as shut down, restart, and so on

Oracle VM Server

VM Server is a physical server which is installed with a very thin layer of Linux, and complemented with the Xen hypervisor technology. The VMs are then installed on this layer, thus effectively consolidating and aggregating multiple platforms, such as Windows and Linux on Oracle VM Server.

Oracle VM Agent

This is installed with Oracle VM Server and essentially communicates with the Oracle VM Manager to manage the VMs in variety of ways. Now let's take a quick look at the Oracle VM Architecture in the following illustration:
