The oVirt project is excited to announce the general availability of oVirt 4.5.5, as of December 1st, 2023.

Important notes before you install / upgrade

If you’re going to install oVirt 4.5.5 on RHEL or similar, please read Installing on RHEL or derivatives first.

Suggestion to use nightly

As discussed in oVirt Users mailing list we suggest the user community to use oVirt master snapshot repositories ensuring that the latest fixes for the platform regressions will be promptly available.

This oVirt 4.5.5 release is meant to provide what has been made available in nightly repositories as base for new installations.

If you are already using oVirt master snapshot you should already have received this release content.
