Red Hat Enterprise Virtualization

Red Hat Enterprise Virtualization (RHEV), an enterprise virtualization product produced by Red Hat, based on the KVM hypervisor. Red Hat Enterprise Virtualization uses SPICE protocol and VDSM (Virtual Desktop Server Manager) with a RHEL-based centralized management server. It can acquire user and group information from an Active Directory service or FreeIPA Active Directory emulator. Some of the technologies of Red Hat Enterprise Virtualization came from Red Hat's acquisition of Qumranet. Other parts derive from oVirt.

Versions

Red Hat Enterprise Linux

Red Hat Enterprise Linux (RHEL) is a Linux distribution developed by Red Hat and targeted toward the commercial market. Red Hat Enterprise Linux is released in server versions for x86, x86-64, Itanium, PowerPC and IBM System z, and desktop versions for x86 and x86-64. All of the Red Hat's official support and training, together with the Red Hat Certification Program, focuses on the Red Hat Enterprise Linux platform. Red Hat Enterprise Linux is often abbreviated to RHEL, although this is not an official designation.

The first version of Red Hat Enterprise Linux to bear the name originally came onto the market as "Red Hat Linux Advanced Server". In 2003 Red Hat rebranded Red Hat Linux Advanced Server to "Red Hat Enterprise Linux AS", and added two more variants, Red Hat Enterprise Linux ES and Red Hat Enterprise Linux WS.

Red Hat uses strict trademark rules to restrict free re-distribution of their officially supported versions of Red Hat Enterprise Linux, but still freely provides its source code. Third-party derivatives can be built and redistributed by stripping away non-free components like Red Hat's trademarks, including community-supported distributions like CentOS and Scientific Linux, and commercial forks like Oracle Linux, which aim to offer 100% binary compatibility with Red Hat Enterprise Linux.
