The oVirt project is excited to announce the availability of oVirt 4.5.0 Alpha release for testing , as of March 16th, 2022.

 

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 on top of oVirt 4.4.

Important notes before you try it

Please note this is an Alpha release.

The oVirt Project makes no guarantees as to its suitability or usefulness.

This pre-release must not be used in production, and it is not feature complete.

In particular, please note that upgrades from 4.4 and future upgrades from this alpha to the final 4.5 release from this version are not supported.
