Can I run on DomU a Dom0 Kernel? So that This DomU will act as a Dom0 for other DomU on top of it?

No.  The question makes no sense since both dom0 and domU both run on top of the bare metal xen hypervisor.

It's amazing how fast people will jump on a topic and respond without actually trying to figure out what he's asking.
He asked if a DomU could act as a Dom0 which is not the right way to ask the question (obviously by the number of "no" answers with no explanations). What I think he wants to do and the OP can correct me if I'm wrong is nest his VMs and currently this is possible but only to one level. Your DomU needs to be HVM and you can run more PV DomUs in it. This will change once Xen adds hardware nesting ability in Xen. Watch the Videos that were linked by Pasi and you can see that they're working on it. KVM and VMware nest and I believe both are utilizing VM nesting in hardware.

Some people, when confronted with a problem, think "I know, I'll use Windows."
Now they have two problems.
