Summary
Red Hat Bug Fix Advisory: Red Hat Virtualization Host (redhat-virtualization-host) 4.3.9 async

Notes

Topic
An update for redhat-virtualization-host is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7.
Details
The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host. 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. Includes fixes for CVE-2018-14404. Changes to the redhat-virtualization-host component: * The Red Hat Virtualization Host could not be deployed successfully on systems with an AMD Epyc CPU. In this release, Red Hat Virtualization Host deployment is successful. (BZ#1796967)
