You can have an OpenNebula installation in each cluster, and then manage
both using OpenNebula Zones [1].

Using the shared FS storage model [2], OpenNebula can work with an
underlying distributed FS, it is "transparent" to OpenNebula and it doesn't
have to configured. In this thread [3] you will find some experiences from
other users. However, I would consider this approach only to combine the
storage within each cluster, because of performance.

I'm not aware of any hypervisor that will allow you to do that, and I can't
even start to image the awful performance you would get using RAM shared
over the internet...
