Detail
Problem Description: An update for redhat-virtualization-host is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. 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. 2. Relevant releases/architectures: RHEL 7-based RHEV-H for RHEV 4 (build requirements) - noarch, x86_64 Red Hat Virtualization 4 Hypervisor for RHEL 7 - noarch 3. Description: 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 following packages have been upgraded to a later upstream version: imgbased (1.1.9), ovirt-node-ng (4.3.5), redhat-release-virtualization-host (4.3.5), redhat-virtualization-host (4.3.5).
