I am running on CentOS 5.4 
xen_major              : 3
xen_minor              : 1
xen_extra              : .2-194.3.1.el5

I have memory=8G and maxmem=8G in my HVM config file and I am trying balloon up 
and down between 1G and 8G. This works with x64 Windows. With x32 I see the 
change only within Windows i.e. Free memory in task manager. Xentop does not 
reflect the change. BTW, this is with the latest PV driver from James.

What is the warning message that I should be seeing on the console? I am not 
seeing anything on the console or in xend.log.
