So here I again installed the tools
make install-tools PYTHON_PREFIX_ARG= (here I had not undone the step
which I did in previous compile make install-tools)  and rebooted in
this new Xen-4.0.1
and pv-ops Dom0 kernel
I can see xm help with options coming but if I type
xm info then

 I see following output

xm info
Error: Unable to connect to xend: No such file or directory. Is xend running?

Here I as root did /etc/init.d/xend start
but even after that I got the same message

xm info
Error: Unable to connect to xend: No such file or directory. Is xend running?

So what is missing in the above step?
