Of the three possible parameter combinations for virtio_queue_set_host_notifier_fd_handler: - assign=true/set_handler=true is only called from virtio_device_start_ioeventfd - assign=false/set_handler=false is called from set_host_notifier_internal but it only does something when reached from virtio_device_stop_ioeventfd_impl; otherwise there is no EventNotifier set on qemu_get_aio_context(). - assign=true/set_handler=false is called from set_host_notifier_internal, but it is not doing anything: with the new start_ioeventfd and stop_ioeventfd methods, there is never an EventNotifier set on qemu_get_aio_context() at this point. This is enforced by the assertion in virtio_bus_set_host_notifier. Reviewed-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Michael S.
