It's always a little tricky to ask questions like this on mailinglists
of "competing" projects. Readers would have to detect whether it is a
trolling attempt or not. 

I cannot fathom, how many productive installations of OpenStack exist
today. That's why it might be very difficult to find people or
organisations that switched from OpenStack to OpenNebula.

At the same time, I'm interested in OpenStacks general architecture
(which I found after a few clicks under
http://nova.openstack.org/nova.concepts.html). 

What I like about Nova is, that it support UML from the beginning.
That's something I'd like to see in OpenNebula as well (or OpenVZ or
LXC for that matter). 
Furthermore, as an OpenNebula user I'm interested in Swift and whether
it can be integrated into OpenNebula as storage for VMs.

At the moment there seems to be no reason to change from OpenNebula to
OpenStack. And the only reason why Nasa and Rackspace have not
considered OpenNebula as their new platform might be the effort that
already went into the various components from which OpenStack was
"composed". 

I like, that OpenNebula doesn't want to impose certain constraints on
the users regarding his or her infrastructure. It integrates itself
very well into existing setups. As a good toolkit should do.

Kind regards,
