If this were an error, it would say ERROR instead of DEBUG. Is anything not working?

Me too.

We enabled Nova Debug=True option, and we see similar in our logfile.

and it seemed that the policy check took a few seconds to complete.

Why do you think it's an error?

I just want to understand wy this policy check (os_compute_api:os-extended-server-attributes) failed.

cshen gravatar imagecshen ( 2017-06-09 16:24:41 -0500 )edit

Extended server attributes like the hypervisor host of an instance are not visible to normal users. This is by design, and I guess it's enforced by policy. Run openstack server show as admin and as normal user and compare the outputs.

Thanks Bernd. You're right. os-extended-server-attributes is an admin api. Need admin role.
