You mean to say a kernel that was for pv-ops sources would run like a
normal Dom0 kernel (no pv-ops)
what is the difference between a Dom0 kernel which runs on Xen and
pv-ops Dom0 kernel.
Both run on Xen.If I am not mistaken then pv-ops Dom0 kernel is built
using jeremy's tree and is itself a para virtualized Dom0 kernel.
Where as in case of non pv-ops Dom0 kernel they are not para
virtualized i.e. normal Dom0 kernel which runs on Xen is
HVM.Correct me if I am wrong.

Well thanks for the guide.What this link mentions is if I understand
correctly is to compile a kernel the Debian way.
What my understanding upto now about Xen is If I just install
Xen-4.0.1 on my system then (and I do not compile a Kernel with Xen
options for Dom0) then Xen won't work.So what I am curious to know is
how can I or how should I go to compile a kernel so that when I
install Xen
I can use Dom0 also.

Or do I not need to go through this painful process and simply
installing Xen and making changes in Grub (no new Dom0 kernel)
to use xen.gz with the kernel which was installed from the Ubuntu CD
is sufficient.
