Red Hat Enterprise Virtualization (RHEV) is a virtualization solution based on Red Hat Enterprise Linux. Its advanced functionalities allow enterprises to centrally manage their virtual environments while reducing the cost and complexity of large deployments.
Components
The RHEV platform consists of the following components:
Red Hat Enterprise Virtualization Manager which allows system administrators to view and manage virtual machines via a single graphical user interface.
Hosts running Red Hat Enterprise Virtualization Hypervisor or Red Hat Enterprise Linux where virtual machines are hosted.
Interfaces
The Red Hat Enterprise Virtualization Manager includes an Administration Portal and a User Portal.
The Administration Portal is designed for setting up, configuring, and managing the Red Hat Enterprise Virtualization environment.
The User Portal allows users to start, stop, reboot, and connect to virtual machines.
Storage domains
The RHEV platform uses the following storage domain types:
Data domains store virtual disks, templates and snapshots. A data domain cannot be shared across different data centers. A data domain can be organized by using NFS, SAN (iSCSI/FCP-connected storages), or a local storage of a virtualization host.
ISO domains store ISO files used to install and boot operating systems and applications for the virtual machines. An ISO domain can be shared across different data centers. An ISO domain can only be organized by using NFS.
An export domain is used to copy or move images between data centers and RHEV Manager installations. An export domain can be moved between data centers. However, it can only be active in one data center at a time. An export domain can use NFS or SAN (iSCSI/FCP-connected storages).
