Hi all, 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, shawn 2008-10-29 Y.

I think you need an "EVTCHNOP_unmask" invocation for the port in domain A. -- Paul S. On Wed, Oct 29, 2008 at 9:47 AM, Y.
