You can have an OpenNebula installation in each cluster, and then manage both using OpenNebula Zones [1]. > 2- can I make Virtual storage from these 2 clusters, i.e. combine the hard > disk of all nodes in the 2 clusters to form virtual storage? > 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. > 3- can I make Virtual Ram from these 2 clusters, i.e. combine the main > memory of all nodes in the 2 clusters to form virtual Ram? > 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...
