Thanks for the tip. Fedora xen rpm worked. Previously i was using source packages. But what is the solution if i use source package? I renamed the file xen-evtchn to evtchn in modules folder and did depmod , it didn't work. Anything i need to change in source files ?

Latest Fedora xen-3.4.2 rpms should take care of that. If you installed from source, then that's likely your problem. -- Pasi </blockquote></div>
