The RHEV 3.3 release is built on top of the open-source oVirt project, which is led by Red Hat. The new release adds support for the Red Hat Enterprise Linux 6.5 platform, improves performance and supports a wider array of systems.
The RHEV platform is one component in Red Hat’s overall virtualization and cloud efforts, which also include the open-source OpenStack cloud platform. Red Hat’s RHEV platform pre-dates the company’s involvement in OpenStack, with RHEV’s genesis coming from technology that Red Hat originally acquired from Qumranet in 2008.
