Hi,

As I see this is an issue hard to get help on, I'll ask it otherwise:

Alternatively to backup and restore, is there a way to migrate an oVirt-manager installation to other machine? We're trying to move the manager machine since the current physical machine is getting short of resources, and we already have a prepared physical host to migrate it to.

If there's an alternative way to migrate it, I'd be very grateful if someone could shed some light on it.

Thanks.

Hi,

I'm restoring a full ovirt engine backup, having used the --scope=all
option, for oVirt 4.3.

I restored the backup on a fresh CentOS7 machine. The process went well,
but when trying to log into the restored authentication system I get the
following message which won't allow me to log in:

    The provided authorization grant for the auth code has expired.

What does that mean and how can it be fixed?

Can you please check also this thread:

https://lists.ovirt.org/archives/list/users@ovirt.org/thread/YH4J7GG7WLOLUFIADZPL6JOPDETJ23CZ/

What version was used for backup, and what version for restore?

For backup, version 4.3.8.2-1.el7 of ovirt-engine-tools-backup was used.

For restore, version 4.3.10.4-1.el7 of ovirt-engine-tools-backup was used.

Did you have a 3rd-party CA cert installed?

I am using a custom LetsEncrypt certificate in apache. I have this certificate configured in httpd and ovirt-websocket-proxy, but it's exactly the same certificate I have configured in the oVirt installation that was backed up (as I understand it, it's not the same case than the one described in the link - I might be wrong). So I copied the same certificate on the other side too.

Please verify that it was backed up and restored correctly, or manually
reinstalled after restore.

As per the logs, both processes ended correctly, no errors showed up. I also run the 'engine-setup' command on the restored machine, and it ended with no errors/warnings.

I'm attaching an engine.log of the restored node in case it helps, from the moment I restart the engine and try to log in.

Thanks for any help regarding this, as I can't figure out what else could be happening.

Nicolás

Good luck and best regards,
