I called the xc_evtchn_notify(). But I see no message/notification in /dev/xen/evtchn (in either DomU or Dom0). I did a little research and found there might be problem with my xen-evtchn module. However it is statically compiled into my kernel and i can see the following contents in /proc/xen

ls /proc/xen/
balloon  capabilities  privcmd    xenbus    xsd_kva  xsd_port

For now I just  want to send and event and acknowledge it (later application will be built on top of this).

/dev/xen/evtchn allows a usermode program to wait for specific event
