Abstract
This guide documents the concepts, components, and technologies used in a Red Hat Enterprise Virtualization environment. It is intended as a conceptual exploration rather than a task orientation guide. It should be read to gain a deeper understanding into how Red Hat Enterprise Virtualization works. The Technical Reference guide will cover the interactions the Red Hat Enterprise Virtualization manager and hypervisors have with existing infrastructure including directory services, storage devices and existing installations of Red Hat Enterprise Linux or previous versions of Red Hat Enterprise Virtualization.
