I've reinstalled ovirt 4.4 on my server remotely via cockpit terminal. I'm able
to access the ovirt admin screen remotely from the laptop that I used for the install.
However, using the same URL I'm unable to gain access to the admin screen.
Following the instruction in the documentation I've modified the file:
/etc/ovirt-engine/engine.conf.d/99-custom-sso-setup.conf, to reflect the DNS name and I
enter in the IP address. But I'm still unable to access the screen from the server
console.
What else needs to change in order to gain access from the server console?
Thanks

I'm seeking help with my issue related to display the ovirt UI Web Admin Screen on my
server. I'm very puzzled by this because I can display the UI on a remote machine
with no issue. I install ovirt on my server remotely connected to the server via ssh, I
had no issues performing the install. As I said earlier I'm able to bring up the
Admin UI remotely on the same machine that was connected remotely.
What really puzzle me is that, I'm able to bring up the UI remotely but not on the
server console. They both are using the same release RHEL 8 and Firefox. When I try to
bring up the UI on the server console I get the following message:
404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is
temporarily unavailable.
I confirmed that all of the installed files are stored on the server, where should I start
looking?
My Server has four/4 network adapters installed with different IP addresses assigned. My
DNS has the domain entered for each network adapter all pointing to the same server. My
DNS entry for ovirt is "AAAABBBB.1234.net" specified four/4 time with a
different IP address for each network adapter.
Does the install of ovirt latch to a specific network adapter and IP Address?
Could this be a permission issue on the server? I'm using the same account and UID on
both server and workstation.
What ever it might how do I start the debugging process to create a solution?
I'm very new to ovirt and Linux so I'm trying to learn.
Thanks

httpd is configured (keeping its default) to listen on 0.0.0.0 (all
addresses) (and this is why it does manage to give you a 404 answer).
It still might be related to your specific networking configuration, though.
As a start (and IMO also always) I'd give each IP address its own
different name, and use the name provided to engine-setup for the
question about the machine's FQDN for the address you want to use the
web interface for. When connecting from a different machine, your
stack probably automatically connects to the correct address (perhaps
due to routing/firewalling/whatever?). When running locally, all can
work.
That said, I can't tell why it does not work - I think it should have,
as-is. Might be something else? E.g. we are quite picky about name
resolution, both forward and backward. Perhaps some of your PTR
records are wrong?
Did you change anything on the machine other than configuring
networking and running engine-setup? Perhaps changed apache httpd's
configuration?
Could this be a permission issue on the server? I'm using the same account and UID
on both server and workstation.
Unlikely.
What ever it might how do I start the debugging process to create a solution?
You can start by checking logs - both /var/log/httpd/* and
/var/log/ovirt-engine/* .
I'm very new to ovirt and Linux so I'm trying to learn.
Good luck!
May I note, that most experienced Linux/Unix sysadmins do not install
browsers on their servers, do not have GUIs there, etc., and so your
case is rather unique. If it's only for "ease of use", perhaps you
should give up and connect only from a remote browser. Running a
GUI/browser on a server is generally not recommended - it's a ton of
software that's often less security-scanned/audited, you risk
connecting to rogue websites, etc. If it's for a technical reason -
because you need some functionality and that's the only way - feel
free to ignore.
Best regards,

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.

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.

Interestingly, I was able to load the ovirt web console remotely with no issues. however,
the issue that I've been experiencing is when I try to load the web console when
logged on the the server.
Can you help me understand the difference?

Have you checked with 'curl' if any error is generated ?

I got things working.
Thanks so much for your help.
Thanks

I figured it out. set the username to root, and pswd that you use for the root. Set the
alternate sign in to the server's IP, then it should work.
