What I see in this conversation is that we are talking about multiple different user classes.

Infra-operator needs as much info as possible, so if it is a vendor driver that is erring out, the dev-ops can see it in the log.

Tenant-operator is a totally different class of user.  These guys need VM based logs and virtual network based logs, etc., but should never see as far under the covers as the infra-ops *has* to see.

So, sounds like a security policy issue of what makes it to tenant logs and what stays "in the data center" thing.  

There are *lots* of logs that are being generated.  It sounds like we need standards on what goes into which logs along with error codes, logging/reporting levels, criticality, etc.

Security by cloud obscurity?

I agree we should evaluate information sharing with security in mind.
However, the black boxing level we have today is bad for OpenStack. At a
certain point once you've added so many belts and suspenders, you can no
longer walk normally any more.

Anyway, lets stop having this discussion in abstract and actually just
evaluate the cases in question that come up.
