Controller nodes
The following services are new for Controller nodes. Add them to your Controller role.
| Service | Reason |
|---|---|
|
| Service for the internal instance of the Image service (glance) API to provide location data to administrators and services that require it, such as the Block Storage service (cinder) and the Compute service (nova). |
Compute nodes
By default, 17.1 Compute nodes run the OS::TripleO::Services::NovaLibvirt service. However, if you perform the RHOSP upgrade with the Compute nodes running the OS::TripleO::Services::NovaLibvirt service, the virtual machine instances appear as shut off. To prevent this issue, all Compute nodes that are on RHEL 8.4 must run the OS::TripleO::Services::NovaLibvirtLegacy service, and the container image must be based on UBI-8.
After the RHOSP upgrade, if you want to upgrade your Compute nodes to RHEL 9.2, your Compute nodes must run the OS::TripleO::Services::NovaLibvirt service and the container image must be based on UBI-9, or your virtual machine instances appear as shut off.
For more information about upgrading the operating system on Compute nodes, see Upgrading all Compute nodes to RHEL 9.2 and Upgrading Compute nodes to a Multi-RHEL environment.
