Red Hat Virtualization (RHV) is an x86 virtualization product produced by Red Hat,[2] based on the KVM hypervisor.[3] 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.[4] Some of the technologies of Red Hat Virtualization came from Red Hat's acquisition of Qumranet.[5] Other parts derive from oVirt.[6] Before 2016, up to version 3.x product was named Red Hat Enterprise Virtualization (RHEV).

RHV supports scheduling policies that define the logic by which virtual machines are distributed among hosts.[7]

RHV supports up to 400 hosts in a single cluster and no limit for the maximum number of virtual machines.[8] It also support hot plugging virtual CPUs[9] also allows to run unlimited guest machine in comparison with RHEL which is limited to 4 guest machines.[10]

RHV solution is based on two primary software components[11]

  • Red Hat Virtualization Manager (RHV-M)
  • Red Hat Virtualization Hypervisors or hosts: Red Hat Enterprise Linux or RHV Host (RHV-H)
