It looks like you still have incompatible versions of things installed.

The configuration library changed during grizzly. The old version and new
version cannot be used together in the same program because they both try
to modify different copies of a global variable. The exception you're
getting is, I think, due to the fact that the API service loads the
keystone middleware to handle authentication. You have a version of the
middleware that uses oslo.config, and a version of ceilometer that uses the
older oslo-incubator version of the configuration library.

The ceilometer team is small, so we have limited capacity to support "old"
versions (especially pre-incubated versions). We do intend to support
grizzly, but can only offer moderate help with folsom. The g2 release
tarballs *should* be compatible at the communication layer with folsom
versions of the other components, but it looks like you can't install them
into the same Python installation as the other services.

You can separate ceilometer code from the other services a couple of
different ways. The simplest would be to use a separate VM to run
ceilometer. That would let you follow all of the normal instructions, and
ensure that you don't have mismatched versions of libraries. The other way
is to install ceilometer into a virtualenv. That would take more care,
since you need to ensure that the virtualenv does not look at the globally
installed site-packages. I haven't tried doing this, so I can't provide
more detailed steps, and you will likely need to experiment a bit to get it
right.

The one piece of ceilometer that does *need* to be installed in the same
location as the other services is the plugin for the nova compute agent. We
spent a fair amount of time making sure there was a version of that plugin
compatible with folsom, so we believe it should work. However, if you are
just testing ceilometer, or not using it for billing instance-hours, you
could skip deploying that piece entirely.
