(RHSA-2022:6551) Important: Red Hat Virtualization security update

The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. 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 ovirt-node-ng packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. 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: redhat-release-virtualization-host (4.5.2), redhat-virtualization-host (4.5.2), redhat-virtualization-host-productimg (4.5.2). (BZ#2070049, BZ#2093195)
