This is a xen-x86 limitation for all guests together. Originally, it was 
planned that more than 4GB of system memory would only be supported for 
64 bit hosts (e.g x86-64), but there is an effort afoot make PAE 
extensions work in xen so that regular x86 hosts could support more than 
4GB. As far as I know, it is not functional yet.
