Tim,
thanks for your vision. Reducing load average on Rabbit is a good reason to
use cells. Technically RPC is a kind of bottleneck on large number of
hypervisors but I think dividing cluster on small peaces is just increasing
number of bottlenecks. May be it's better improve RPC mechanism (in term

Your configuration looks right to me. Seems a browser or plugin issue. Can you
try browsers like google chrome and firefox.

Tim,
We currently run a bit more than 20k hypervisors on a single cell. We had
three major problems with getting this large: RPC, DB and scheduler. RPC is
solvable by getting away from the hub-spoke topology that brokered
messaging forces you into, AKA, use 0mq. DB was overcome by a combination
of
Got it. By RPC I was referring to RabbitMQ in particular. That's also the
rationale that Rackspace presented at the Portland summit.

Chris,
Great to see further improvements are in the pipeline. The cinder support for
cells in Havana is a very welcome development.
For our Grizzly instance, we're also seeing some issues around flavors /
availability zone definition along with some ceilometer functions.
It would be good to h

Not just RPC, but RPC is a big one. Cells gives the ability to split up and
distribute work. If you divide hypervisors int

The CMS farm was the further ahead and encountered problems with the number of
database connections at around 1300 hypervisors. Nova conductor help

At CERN, we're running cells for scalability. When you go over 1000 hypervisors
or so, the general recommendation is to be in a cells configuration.
Cells are quite complex and the full functionality is not there yet so some
parts will need to wait for Havana.

I've really interested in cells but unfortunately i can't find any useful
use cases of them.
For instance I have 4 DCs and I need single entry point for them. In this
