I think that what Fui Fui Wong refers to as a cluster is a vmware cluster - equivalent to to a resource pool in XCP - a group of machines of similar cpu spec which allow you to do HA and live migration etc. 
 
 The number of clusters/resource pools that can be handled by XCP is more a question about the management software rather than XCP itself - the hosts themselves don't know anything about the other resource pools. So how many resource pools can you have - unlimited I guess. How many can you manage from one app? That depends on the management software.

  I seem to recall seeing something in the XCP roadmap about eventually federating clouds, but it's still one cloud per set of hardware.

Hi,   
  
are u mean that currently, XCP does not support multiple cluster in a single cloud. 
  
Thanks,
