Hello all,
I have a question if it is possible to connect 2 Openstack clouds to use
the ressources together?
We have a Mitaka installation at our site and we have colleagues who
also have a mitaka installaton at their site which are both independent
at the moment. We want to create a site-to-site vpn tunnel between our 2
management networks (with openvpn) so that both installations can see
each other, and we searching now for a possibility to connect both together.
Is there already some way to connect both controllers so the users of
the one site can also use the resources of the other site and start
instances there from their controller on the other controller?
How is this done in large installations when 2 clouds should be
connected to each other? Is this even possible?
Quick overview of various ways to do related things here:

In short, you can run up another nova-api running nova-cells to be a
"parent" of the two installations. Then your users (and horizon) can
connect to that and see all the resources.

Pretty advanced usage though, so you might want to become fast friends
with the "Large Deployment Team", many of whom run this configuration :)
