That's not enough - please check/share all files there. Thanks.

From the log, it seems like dwh db was not included, which probably means
that it was either remote (dwh on a separate machine) or you passed
'--scope=files --scope=db'
when taking the backup. If latter:

1. Where did you find instructions to do this? This should be fixed.

2. Please try again, either without --scope, or with --scope=all, or
'--scope=files --scope=db --scope=dwhdb'.

If it's former (dwh+its db are on a separate machine), then the
documentation is not yet up-to-date - please see also:

I am only aware of:

https://github.com/oVirt/ovirt-ansible-collection/tree/master/roles/hosted_engine_setup#make-changes-in-the-engine-vm-during-the-deployment

The code moved there recently - before that, it was in:

https://github.com/oVirt/ovirt-ansible-hosted-engine-setup

There are a few examples scattered around the net, in this mailing
list, bugzilla, etc. One I wrote myself recently is
"required_networks_fix.yml" mentioned there (and included inside
examples/).
