oVirt 4.4.7 Release Notes

The oVirt Project is pleased to announce the availability of the 4.4.7 Fourth Release Candidate as of June 17, 2021.

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 8.4 (or similar) and CentOS Stream.


Starting from oVirt 4.4.6 both oVirt Node and oVirt Engine Appliance are based on CentOS Stream.

Please note that if you are upgrading oVirt Node from previous version you should remove CentOS Linux related yum configuration. See Bug 1955617 - CentOS Repositories should be removed from yum.repo.d when upgrading to CentOS Stream For more details.

To find out how to interact with oVirt developers and users and ask questions, visit our community page. All issues or bugs should be reported via Red Hat Bugzilla.

The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release should not to be used in production, and it is not feature complete.

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.

Known issues

How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1

Due to [Bug 1837864] - Host enter emergency mode after upgrading to latest build,

If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.7 you may get your host entering emergency mode.

In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts:

  1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted).
  2. Reboot.
  3. Upgrade to 4.4.7 (redeploy in case of already being on 4.4.7).
  4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place.
  5. Only if not using oVirt Node:
    • run “dracut –force –add multipath” to rebuild initramfs with the correct filter configuration
  6. Reboot.

What’s New in 4.4.7?

Release Note

oVirt Engine WildFly

  • BZ 1938101 Rebase on Wildfly 23

    oVirt Engine now requires WildFly 23

oVirt Engine Data Warehouse

  • BZ 1966574 Update the required Grafana to 7.3 in ovirt-dwh

    Required Grafana version changed from 6.7 to 7.3.

oVirt Engine

  • BZ 1963748 [RFE] Upgrade to EAP 7.4 in RHV 4.4.7

    Red Hat Virtualization 4.4.7 now requires EAP 7.4

  • BZ 1966145 Remove version lock on specific ansible version and require ansible 2.9.z >= 2.9.21 in ovirt-engine

    ovirt-engine in RHV 4.4.7 requires ansible 2.9.z higher than 2.9.20. Also in RHV 4.4.7 version for specific ansible version has been removed, because correct ansible version shipped in RHV channels.

  • BZ 1938101 Rebase on Wildfly 23

    oVirt Engine now requires WildFly 23


  • BZ 1964522 Allow both automatic detection of IP version available as well as manual configuration

    To solve issues in mixed Pv4/IPv6 setups following changes has been done:

  1. A new option pool.default.socketfactory.resolver.detectIPVersion

    to enable/disable automatic detection of IP protocol has been


    • By default set to true

    • Automatic detection of IP versions has been improved to use

      the default gateway IP addresses (if a default gateway has

      IPv4/IPv6 address, A/AAAA DNS records are used to resolve LDAP

      servers FQDNs)

    • If automatic detection is disabled, then administrators need

      to set properly below options according to their network setup

  2. A new option pool.default.socketfactory.resolver.supportIPv4

    to enable/disable usage of IPv4 has been introduced:

    • By default set to false (automatic detection is preferred)

    • If set to true, type “A” DNS records are used to resolve LDAP

      servers FQDNs

  3. Existing option pool.default.socketfactory.resolver.supportIPv6

    is used to enable/disable usage of IPv6

    • By default set to false (in previous versions it was enabled)

    • If set to true, type “AAAA” DNS records are used to resolve

      LDAP servers FQDNs

So by default automatic detection of IP version using the default gateway addresses is used, which should work for most of the setups. If there is some special mixed IPv4/IPv6 setup, where automatic detection fails, then it’s needed to turn off automatic detection and configure IP versions manually as a part of /etc/ovirt-engine/aaa/<PROFILE>.properties configuration for specific LDAP setup.


oVirt Engine Data Warehouse

  • BZ 1948418 [RFE] Add memory, and CPU sizes to Hosts/Virtual Machines Trend dashboard


added to hosts and vms trend dashboards 2 panels. one withe the total memory size, and one with the total cpu cores.

  • BZ 1849685 [RFE] Handle PKI renew for grafana

    engine-setup now allows renewing the certificate also for grafana when it is set up on a separate machine from the engine.

  • BZ 1952424 [RFE] Add Data Source variable to all dashboards

    Feature: Add the option to select Data Source for all dashboards.


This way we can navigate easily if there are several different engines (with different dwh).

oVirt Engine

  • BZ 1958081 [RFE] Enable ramfb for mdev with display=on

    When a vGPU is used and nodisplay is not specified, an additional framebuffer display device is added to the VM now, allowing to display the VM console before the vGPU is initialized. This allows display console access during boot, instead of having just a blank screen there as before this change.

This works only on cluster levels >= 4.5. It is possible to disable the feature by setting VgpuFramebufferSupported Engine config value to false.
