An update for openvswitch2.11, ovirt-ansible-repositories, ovn2.11, and python-ovirt-engine-sdk4 is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7 and Red Hat Virtualization Engine 4.3.

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.

Bug Fix(es):

• Previously, during RHHI-V deployment of 3 hosts using ovirt-ansible-hosted-engine-setup, the Self-Hosted Engine was added to the default cluster, but the additional 2 hosts were not added. In this release, deployment with ovirt-ansible-hosted-engine-setup successfully adds all hosts to the cluster. (BZ#1855283)

• Previously, when creating large numbers of virtual machines (~2300 VMs), the associated Data Centers became unresponsive, and the hosts did not have Storage Pool Managers (SPM). With this release, large scale deployment of virtual machines succeeds without errors. (BZ#1849558)
