Everything but nova is on a VM running on RHEL 6.4 and KVM (RHEV). I have one nova node that refers back to the "all the rest" VM running on hardware that supports KVM.

Dashboard is doing a login, authenticated by keystone. The request from the browser that fails is this:

GET /dashboard/admin/ HTTP/1.1
Host: rhopenstack.example.com
User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:21.0) Gecko/20100101 Firefox/21.0

That triggers an internal request to the nova API daemon:

GET /os-simple-tenant-usage?start=2013-06-01T00:00:00&end=2013-06-25T10:52:36.348852&detailed=1 HTTP/1.1

I don't understand what you mean by "nova usage". I'm quite sure that the installation instructions from Red Hat are missing something, so far they proved not to be exact. Many copy-and-pastoes, etc. Very entertaining. Anyway, I have no idea *what* needs to be done to make the nova API daemon return the tenant_usage data. I can't use the dashboard to create any objects...
