Red Hat Enterprise Linux OpenStack Platform uses the Red Hat Enterprise Virtualization (RHEV) hypervisor, which is based on the open source KVM hypervisor. The distribution became available in June 2013 and runs on any hardware certified for Red Hat Enterprise Linux (RHEL).
Each release of the Red Hat Enterprise Linux OpenStack Platform aligns with an open source community release of OpenStack and a stable release of the Linux operating system (OS). Red Hat tests and certifies the OpenStack and Linux releases for hardware and software compatibility and performance. Red Hat also provides security and bug fixes for the platform and provides advanced virtualization and networking features for cloud deployments.
