4GB of RAM may be the maximum your kernel got - assuming its a x86,
you may need special code to support more than 4GB of RAM. 

So, as Xen manages your RAM, and it seems like it does not support
more than 4gb (does anyone else :) ?), you should contact some 
xen-developers asking for support, and wait for the next release.
