Dear Jose Manuel, The setup that you are proposing will indeed pose a problem. The reason being that OpenNebula assumes an exclusive use of the resources, so the capacity calculus will be render useless, and this will end up in poor placement decisions. Moreover, all the OpenNebula instances will use the same "one-id" notation for VM names, and so some conflicts may arise when two OpenNebula try to deploy VMs with the same ID on the same host.
We are currently working on High Availability for OpenNebula, and also in multi-tier deployments, which will improve ONE's feature set and also its scalability.
