The Red Hat Enterprise Virtualization platform consists of one or more Hypervisors (or hosts) and at least one Manager. The virtual machines (or guests) are hosted on the Hypervisor. The system and all of its components are managed through Red Hat Enterprise Virtualization Manager.
Red Hat Enterprise Virtualization Manager
RHEV-M acts as a centralized management system that allows system administrators to view and manage virtual machines and images. The Red Hat Enterprise Virtualization Manager provides a comprehensive range of features including search capabilities, resource management, live migrations and provisioning.
The Red Hat Enterprise Virtualization Manager is able to manage hosts running Red Hat Enterprise Virtualization Hypervisor and Red Hat Enterprise Linux 5.4 or newer
Red Hat Enterprise Virtualization Hypervisor
RHEV-H is a thin virtualization layer deployed across the server infrastructure. It is based on Kernel-based Virtual Machine (KVM), which is a core component of the Linux kernel.
The Red Hat Enterprise Virtualization Hypervisor is a stand-alone Red Hat Enterprise Linux installation developed specifically for use with Red Hat Enterprise Virtualization. It is also possible to configure Red Hat Enterprise Linux 5.4 or newer to be used as a host. Red Hat Enterprise Linux hosts can be used concurrently with Red Hat Enterprise Virtualization Hypervisors.

How the management system works
The Red Hat Enterprise Virtualization Manager platform consists of one or more Hypervisors (or hosts) and at least one Manager. The virtual machines (or guests) are hosted on the Hypervisor. The system and all of its components are managed through Red Hat Enterprise Virtualization Manager Manager.
Red Hat Enterprise Virtualization Manager Manager provides a graphical user interface to administer the physical and logical resources within the virtual environment infrastructure. It can be used to manage provisioning, connection protocols, user sessions, virtual machine pools, images and high availability/clustering. The Red Hat Enterprise Virtualization Manager 2.1 runs on Windows 2003 server in clustered mode, with active-standby configuration and 2.2 version runs on windows 2008 R2
Red Hat Enterprise Virtualization Manager Hypervisor or Red Hat Enterprise Linux Host runs the virtual machines on Red Hat Enterprise Linux with KVM virtualization technology. It also includes a resource optimization layer that allows for improved virtual machine interactivity and management.
