Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.

The following packages have been upgraded to a later upstream version: cockpit-ovirt (0.14.11), imgbased (1.2.12), redhat-release-virtualization-host (4.4.2), redhat-virtualization-host (4.4.2). (BZ#1875362, BZ#1878045)
