It seems you've runned into a typical misunderstanding of the xen 
architecture.

If you use "top" or other system monitorings on Dom0 then you just (!!!) 
measure the Dom0 parameters / load. Dom0 is just ONE of the xen domains, 
"just" privileged".

There are different ways to get out the machine load out from xen - i.e. 
xentop.

You might compare "top" and "xentop" results on your Dom0 for understanding 
the difference.
