Do you mean autoballooning of dom0?  Before you've started and destroyed any 
guests then I'd guess this is normal - dom0 will have been sized to use all 
available memory.  From Xen's PoV the memory is not free because dom0 
currently owns it; dom0 will free it to Xen before starting a domU when 
autoballooning is active.

Or did you mean something else?
