Description

The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor.

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). (BZ#1669357, BZ#1669365, BZ#1684986, BZ#1711193, BZ#1717250, BZ#1726917)

Security Fix(es):
