To be clear, unique hostnames are not a must. Unique certnames are, which by default are based on hostnames, but they don't have to be. You can programmatically generate those using something like UUID (Which is what Foreman uses for cloud provisioning). See the following for more info on UUIDs: http://en.wikipedia.org/wiki/Universally_unique_identifier
