The oVirt project is excited to announce the general availability of oVirt
4.4.6 , as of May 4th, 2021.

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

Rebase on CentOS Stream

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

You can still install oVirt 4.4.6 on Red Hat Enterprise Linux 8.3,  CentOS
Linux 8.3 or equivalent but in order to use cluster level 4.6 you’ll have
to wait for 8.4 to be available.

Please note that existing oVirt Nodes updating to 4.4.6 will automatically
be based on CentOS Stream.
