AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using fe80::d6f5:efff:fe0f:cd00. Set the 'ServerName' directive globally to suppress this message
That effectively means: "Apache cannot determine what the virtual hostname is supposed to be for an interface it's running on." In this case, the interface in question is whichever one has / had fe80::d6f5:efff:fe0f:cd00 as it's address at the time the error was logged. To fix it, you'll need to set the hostname somewhere. Either in /etc/hosts which will allow you to set it only for the IP address in question, or in Apache's config where it will become the default hostname used as a last resort. Until this is fixed, oVirt won't reliably know what the hostname is for a given connection and therefore SSO, and the web UI, will fail.

This module is for load balancing. It's not required by oVirt. You may want to consider disabling it until you get the web UI working on the server to reduce the chances of it causing problems while you troubleshoot. The rest are just status messages from Apache's startup. -Patrick Hibbs On Sat, 2022-04-09 at 15:47 +0000, louisb@ameritech.net wrote:
This has not been easy to say the least I've been working on this for months and have done several re-installs from scratch to include the OS/RHEL 8.5. Below is a snap shot of the logs, I don't understand what they are trying to tell me about the error, any help is greatly appreciated.
