Updated redhat-virtualization-host packages that fix several bugs and add various enhancements are now available.

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.

Includes GlusterFS fixes for CVE-2018-1088, dhcp fixes for CVE-2018-1111, kernel fixes for CVE-2018-1087, and kernel fixes for CVE-2018-8897.
