True, xenner is also required for KVM. I have used xenner module successfully for my old FC8 (DomU) and it worked fine. On your advice I have tried to created RamDisk without xenner but no luck.

This seems sound, i am using Latest FC10 kernel -2.6.27.7-134.fc10.i686.PAE as DomU and Latest kernel 2.6.21.7-5.fc8xen on FC8 (Dom0). Ideally FC10 pv_ops kernel should have these modules support, either built-in or as module.

Yes you got exactly right,  logically it should work, but its not working.

I am checking fresh installation via virt-install on another box with same setup. I will post results here.
