xen 3.4.2, dom0( jeremy's pvops kernel=A02.6.31.6), domU( vanilla=20 kernel 2.6.32 with paravirt enabled), distribution( ubuntu 9.10 )

It does not work well

what is the problem??
I think current s= ystem is quite stable, newtork, disk, and so on.
Is there anyone who kn= ow this or has experience??
