OK.  The reason I asked was that there was a problem with some older versions 
of Xen when weird stuff would happen if domUs were using network services 
that were running in dom0...  I can't remember what error this gave, but it 
seemed worth ruling out.

If you set dom0_mem on the the command line and don't use any ballooning, do 
you still get this problem?
