Comment 5 for bug 1942709

Thanks for offer. As a first step it would be nice to see the following:

0) turn on the debug logging for the nova-metadata service
1) create an instance with an admin password
2) check that the admin password is visible from inside the guest via the metadata service. Provide the logs from the metadata service for this action.
3) dump the content of the instance_system_metadata table of the nova database for the uuid of the instance you created at #1)
    select * from instance_system_metadata where instance_uuid='<instance uuid>';
Feel free to sanitize the value column of the output before posting it if it contains sensitive information.

Also if you think Mirantis delivered customized Nova for you then look for any changes that might be relevant in nova/api/metadata/ directory compared to mitaka-eol[1] or liberty-eol tags upstream. If not then you can widen the search of changes in the whole nova codebase.
