I haven't been following the thread, but has the discussion been about  
memory limits of Xen?

Am I going to face any issues wanting to run some CentOS 5.x x86_64  
boxes with 16 or 32 GB memory as Xen hosts with up to 10 or 12 GB  
memory CentOS 5.x x86_64 domUs ?

Furthermore, am I going to encounter issues running CentOS 5.x i386  
boxes with 8 GB memory trying to run CentOS 4.x i386 domUs with 3.5 or  
4GB memory?
