The oVirt project is excited to announce the general availability of oVirt 4.4.1 , as of July 8th, 2020.

This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics, as compared to oVirt 4.3.

Important notes before you install / upgrade

Please note that oVirt 4.4 only supports clusters and data centers with compatibility version 4.2 and above. If clusters or data centers are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended).

Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported.

For example, the megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See the users’ mailing list thread on this at )

What’s new in oVirt 4.4.1 Release?

This update is the first in a series of stabilization updates to the 4.4 series.

This release introduces a new monitoring solution that provides a user interface to oVirt DWH collected data using Grafana. This allows admins to track inventory, monitor performance and capacity trends, and easily identify and troubleshoot resources issues. Grafana is installed and configured during engine-setup and includes pre-built dashboards that are based on the data collected by the ovirt_engine_history PostgreSQL Data Warehouse database (BZ#1777877).

In oVirt 4.4.1 the maximum memory size for 64-bit x86_64 and ppc64/ppc64le VMs is now 6TB. For x86_64 this limit is applied also to VMs in 4.2 and 4.3 Cluster Levels.

You can now use CentOS Stream as an alternative to CentOS Linux on non-production systems.

This release is available now on x86_64 architecture for:

  • Red Hat Enterprise Linux 8.2
  • CentOS Linux (or similar) 8.2
  • CentOS Stream (tech preview)

This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for:

  • Red Hat Enterprise Linux 8.2
  • CentOS Linux (or similar) 8.2
  • CentOS Stream (tech preview)
  • oVirt Node 4.4 based on CentOS Linux 8.2 (available for x86_64 only)

oVirt Node and Appliance have been updated, including:
