Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
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: imgbased (1.0.20), redhat-release-virtualization-host (4.2), redhat-virtualization-host (4.2). (BZ#1590664)

- Previously, if systems were configured to skip Logical Volume Manager (LVM) clusters, imgbased sees output that is unrelated to the Logical Volumes that are being queried.
As a result, imgbased failed to parse the output, causing Red Hat Virtualization Host updates to fail.
In this release imgbased now ignores output from skipped clusters enabling imgbased LVM commands to return successfully. (BZ#1568414)
- Starting from version 4.0, Red Hat Virtualization Hosts could not be deployed from Satellite, and therefore could not take advantage of Satellite's tooling features.
In this release, Red Hat Virtualization Hosts can now be deployed from Satellite 6.3.2 and later. (BZ#1484532)
