CentOS Stream 9 support
Add support for CentOS Stream 9 to oVirt project
Name: Sandro Bonazzola
- Last updated: Mon Oct 04 2021 Sandro Bonazzola email@example.com
- Target release: oVirt 4.5.0
- Status: in progress
- Reference bugs:
- [50 %] CI - Support building oVirt project packages on CentOS Stream 9.
- Automation for builiding oVirt Node and its dependencies is in place.
- Missing automation for building oVirt Engine and its dependencies.
- [0 %] CI - Add automation for building and testing oVirt project packages on CentOS Stream 9.
- [0 %] Engine: Support clusters with CentOS Stream 9 based hosts.
- [90%] Host: provide oVirt Node based on CentOS Stream 9 and allow provisioning equivalent host based on CentOS Stream 9 or derivatives.
- oVirt Node builds are available
- oVirt Node based on CentOS Stream 9 is lacking hosted engine setup related packages due to changes in Ansible 2.11.
- Not a goal for this feature but nice to have: oVirt Engine running on CentOS Stream 9 as well.
- mock-core-configs-34.5-1 is needed in order to get CentOS Stream 9 build environment.
Due to the move from Ansible 2.9 to Ansible 2.11 the oVirt Hosted Engine Setup flow needs to be re-designed as Ansible 2.11 requires to be executed within a container.
Benefit to oVirt
oVirt will be able to run on top of CentOS Stream 9 and RHEL 9 once it will be available.
In CentOS Stream 9, RHEL 7 emulated machine are going to be unsupported. VDSM should report the host to be not compatible with cluster level < 4.4.
No CRUD operation needed in oVirt Engine.
No UX change needed in oVirt Engine.
Both ovirt-engine host/appliance and ovirt-node/hosts will require full re-install when upgrading from CentOS Stream 8 or derivatives.
We are not considering in-place upgrade in this design.
No event reporting updates needed.
Dependencies and Related Features
Dependencies not provided by CentOS Stream 9 repositories are handled within CentOS Virtualization SIG or within a repository managed by oVirt project.
ovirt-release-master package will provide the needed repository configuration.
On a plain CentOS Stream 9 system you can install the oVirt packages and their dependencies following the Install nightly snapshot guide.
