Red Hat Virtualization (RHV) is an x86 virtualization product produced by Red Hat, based on the KVM hypervisor. Red Hat Virtualization uses the 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 or FreeIPA domain. Some of the technologies of Red Hat Virtualization came from Red Hat's acquisition of Qumranet. Other parts derive from oVirt. Before 2016, up to version 3.x product was named Red Hat Enterprise Virtualization (RHEV).
RHV support scheduling policies that defines the logic by which virtual machines are distributed amongst hosts.
RHV support up to 400 hosts in a single cluster and no maximum number of virtual machines. It also support hot plugging virtual CPUs also allows to run unlimited guest machine in comparison with RHEL which is limited to 4 guest machines.

- Red Hat Virtualization Manager (RHV-M)
