Xen devel - Sep 2010 - ERROR: While allocating unbound port in remote domain from Dom0

Hi,

I am trying to create an event channel and I am using the below code.

#include <stdint.h>
#include <stdio.h>

#include <xenctrl.h>
#include <xen/xen.h>
#include <xen/event_channel.h>

int main(void){

int xce_handle, src_port, dst_port, xc_handle;

int dom, remote_dom;

dom=0;
remote_dom=15;

xc_handle=xc_interface_open(); //open the hypervisor interface
printf("\n Accquired HYPERVISOR INTERFACE HANDLE: %d \n", xc_handle);


dst_port = xc_evtchn_alloc_unbound(xc_handle, remote_dom, dom); //allocate a
port on the remote domain
printf("\n Allocated the port %d \n", dst_port);

xce_handle = xc_evtchn_open(); //create a handle for event channel
printf("\n Accquired HYPERVISOR INTERFACE EVTCHN HANDLE: %d\n",
xce_handle);

src_port = xc_evtchn_bind_interdomain(xce_handle, dom, dst_port);
printf("\n Allocated the port %d \n", src_port);

return 0;

}


and I am getting the following error:

Accquired HYPERVISOR INTERFACE HANDLE: 3

*ERROR Internal error: do_evtchn_op: HYPERVISOR_event_channel_op failed: -1*

Allocated the port -1

Accquired HYPERVISOR INTERFACE EVTCHN HANDLE: 4

Allocated the port -1
