You've still got the RHEL support issue though - what will RedHat themselves 
support you doing with the system if you install a 3rd party Xen setup?    
I'd be surprised if they'd support > 4 RHEL guests, unless you've paid for 
extra licenses.  I'm not sure exactly how their licensing terms would handle 
this.

Does RHEL actually limit the number of guests you can create, or is it just 
that they'll only *support* up to 4 RHEL guests?  i.e. could you maybe create 
arbitrary numbers of CentOS or Ubuntu guests?

Cheers,
Mark
