Hello,
IIUC, you are running this from the guest instance, to see the metadata of
this instance,
but in your working example, you get it without full URI, i.e.
/opestack/latest/metadata.json.
Its 400, Can you please try $ curl 169.254.169.254/openstack once, along
with ovn-metadata-agent.log check for nova-metadata-api logs as well to see
what request went.
Also, can you tell how your setup is deployed? such as tripleO or
killa-ansible, etc..
Regards
