In a mini-os domain A, I start a thread allocating an event channel:

err = evtchn_alloc_unbound(remote_domid, experiment_handler, NULL, &port);

and registered a handler. The err value is 0. The thread normally exits.

 

While in another mini-os domain B, I start a thread binding that event channel:

err = evtchn_bind_interdomain(remote_domid, remote_port, experiment_handler2, NULL, &port);

and send a event:

err = HYPERVISOR_event_channel_op(EVTCHNOP_send, &event);  Both err is 0. The thread normally exits.

 

but in the domain A, the event handler is not called.

 

What is wrong with it?

 

Thanks,
