oVirt 4.1.7 Release Notes

The oVirt Project is pleased to announce the availability of the 4.1.7 release as of November 7, 2017.

oVirt is a free open-source distributed virtualization solution, designed to manage your entire enterprise infrastructure. oVirt uses the trusted KVM hypervisor and is built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible.

This release is available now for Red Hat Enterprise Linux 7.4, CentOS Linux 7.4 (or similar).

If you’d like to try oVirt as quickly as possible, follow the instructions on the Download page.

For complete installation, administration, and usage instructions, see the oVirt Documentation.

For a general overview of oVirt, read the About oVirt page.

To learn about features introduced before 4.1.7, see the release notes for previous versions.


Don’t enable all of EPEL on oVirt machines.

The ovirt-release package enables the EPEL repositories and includes several specific packages that are required from there. It also enables and uses the CentOS SIG repos, for other packages.

If you want to use other packages from EPEL, you should make sure to use includepkgs and add only those you need avoiding to override packages from other repos.

What’s New in 4.1.7?



  • BZ 1490810 print task list to log in TooManyTasks issue
    Previously, while VDSM performed periodic monitoring and maintenance tasks, operations would occasionally become too slow or even become blocked. In this case, the internal queue became full and the periodic operations were no longer performed. A “TooManyTasks” warning appeared in the log files at a maximum rate of once every 10 seconds.

    In this release, if VDSM cannot perform its periodic operations, in addition to issuing a warning in the log files, VDSM also dumps the contents of the queue into the logs.

oVirt Engine Metrics

  • BZ 1502931 [RFE] Allow passing extra ansible opts to oVirt Metrics shell script

oVirt Engine

  • BZ 1502510 [downstream clone - 4.1.7] Rest API does not report network statistics host “data.current.tx, data.current.rx”
    The precision of rx_rate, tx_rate, rx_drop, and tx_drop of virtual and host network interfaces have been increased. Network traffic 100 times smaller can now be detected on network interface statistics.

    If traffic on the network interface is below the precision of the network interface statistics, it is not reflected in the statistics.

oVirt Hosted Engine Setup

  • BZ 1471658 [HC] Hosted engine deployment should enable gfapi access for cluster
    Feature: Enabling gfapi during HE installation

    Reason: For the HC deployment, we want the gfapi access to be enabled for the “Default” cluster during HE deployment.

    Result: You could use additional config file with:


    to enable libgfapi during HE setup

oVirt Hosted Engine HA

  • BZ 1502653 [downstream clone - 4.1.7] HE host on EngineStarting -> EngineMaybeAway -> EngineDown cycle
    This release adds caching of the OVF storage location. As the OVF storage location rarely changes, it does not need to be searched for on every monitoring loop iteration. Instead it can be saved and reused, and expired only in the case of an error. As a result, the monitoring loop execution time is decreased significantly.

Rebase: Bug Fixeses and Enhancementss
