Thank you very much, Pasi , for your help.
Just a novice question -
when I build xen-4.0.0 (from here http://bits.xensource.com/oss-xen/release/4.0.0/xen-4.0.0.tar.gz) , it
downloads pvops kernel , is there any way I can use
my own pvops kernel instead of this ?
Regards,
Onkar

Yes, Fedora's kernel is pvops, since pvops is in upstream kernel.org kernels.

Just grab latest kernel from kernel.org and build with Xen pvops options enabled.
