[ovirt-users] Problems Installing oVirt 4.5 on Centos Stream 9

Good evening all, *High level goal:* We are preparing to upgrade our hosting OS to Centos Stream 9, and update to the latest oVirt patch level. We are running with a standalone engine. The immediate goal is to stand up a brand new engine on bare metal running CentOS 9. Once the new engine is configured, the engine database will be migrated from the current system production engine to the new to-be production engine and upgraded. After successful engine upgrade, we will be commissioning a new host and then upgrading the hosts in sequence. *Problem:* When installing the ovirt standalone engine, there is a requirement to follow the instructions at https://www.ovirt.org/download/install_on_rhel.html . I found I had to enable both epel and crb (formerly powertools) (both undocumented) before I could complete this step. After following those instructions with the necessary pieces I had identified as missing, I returned to section 3.2 Enabling the oVirt Engine Repositories. The next step is: [root@ovirt2 administrator]# *dnf install -y centos-release-ovirt45* Last metadata expiration check: 0:12:58 ago on Sat 20 Aug 2022 09:50:00 PM CDT. Package centos-release-ovirt45-9.1-2.el9s.noarch is already installed. Dependencies resolved. Nothing to do. Complete! Following this, The commands to enable the repositories all return "Error Unable to find a match: xxxx" Sample: [root@ovirt2 administrator]# *dnf module -y enable javapackages-tools* Last metadata expiration check: 0:03:31 ago on Sat 20 Aug 2022 09:50:00 PM CDT. Error: Problems in request: missing groups or modules: javapackages-tools [root@ovirt2 administrator]# *dnf module -y enable postgresql:12* Last metadata expiration check: 0:07:43 ago on Sat 20 Aug 2022 09:50:00 PM CDT. Error: Problems in request: missing groups or modules: postgresql:12 Please advise. *David Johnson*
