I did a clean install of oVirt manager 4.4.10 on a clean Rocky Linux 8.9. I have found I get through installing and running "engine-setup" successfully without errors. The manager web site errors on "500 internal server error" but the Grafana site works without a problem. I seem to be missing one step or one configuration setting. I'm working with Rocky Linux 8.9 and oVirt 4.4.10 partially to plan for migration, but also because I have older hardware at home I am using to sandbox with. I also plan to test upgrading from CentOS 7.9 with oVirt 4.3.10, so I want to make sure I have a solid installation method Rocky Linux 8.9 and oVirt 4.4.10. (my current method for installing CentOS 7.9 with oVirt 4.3.10 works flawless on hardware, and VMs). When following the documentation for installing oVirt standalone manager on Enterprise Linux on the oVirt web site: https://www.ovirt.org/documentation/installing_ovirt_as_a_standalone_mana... There’s a section specific to "RedHat derivatives" – specifically Rocky Linux https://www.ovirt.org/download/install_on_rhel.html I followed the steps to the best of my ability. Here are the specific steps I took: installed Rocky Linux - minimal install, added "system tools" when that boots up I run these commands in this order: dnf distro-sync --nobest dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm dnf module -y enable javapackages-tools dnf module -y enable pki-deps dnf module -y enable postgresql:12 dnf module -y enable mod_auth_openidc:2.3 dnf module -y enable nodejs:14 dnf install -y https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/x86_64/ovirt-engine-app... (this package gets installed when you run the command: dnf install ovirt-engine-appliance ) dnf install ovirt-engine -y engine-setup I found the documentation says to run adding repos first then install release 4.4 RPM but the Java repo errors out, so I install the RPM first. I could do that last and enable Java afterwards like this: ... everything else... dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm dnf module -y enable nodejs:14 Again, to summarize: I have followed the documentation to the best of my ability and the process succeeds, but it always fails on 500s on trying to launch the manager. The Grafana web site works fine. I should note on the same system I can install CentOS 7.9 and oVirt 4.3.10. It succeeds and works flawlessly. Like I said earlier, I must be missing one step or one configuration setting. Thanks in advance for any help you can provide.
