oVirt is free, open-source virtualization management platform. It was founded by Red Hat as a community project on which Red Hat Enterprise Virtualization is based. It allows centralized management of virtual machines, compute, storage and networking resources, from an easy to use web-based front-end with platform independent access. KVM on x86 64 architecture is the only hypervisor officially supported, but there is an ongoing effort to support PPC and ARM architectures in the future releases.
