2.2. Red Hat Virtualization Hypervisor
A Red Hat Enterprise Virtualization environment has one or more hosts attached to it. A host is a server that provides the physical hardware that virtual machines make use of. Red Hat Enterprise Virtualization Hypervisor hosts run an optimized operating system installed using a special, customized installation media specifically for creating virtualization hosts. Red Hat Enterprise Linux hosts are servers running a standard Red Hat Enterprise Linux operating system that has been customized after installation to permit use as a host. Both methods of host installation result in hosts that interact with the rest of the virtualized environment in the same way, and so, will both referred to as hosts.
