After migration the spicevmc backend on the destination has never been notified of the (non 0) guest_connected state. Virtio-serial holds this state information and migrates it, this patch properly propagates this information to virtio-console and through that to interested chardev backends. rhbz #725965 Signed-off-by: Hans de Goede Message-id: 1364292483-16564-11-git-send-email-hdegoede@redhat.com Signed-off-by: Anthony Liguori --- diff --git a/hw/virtio-serial-bus.c b/hw/virtio-serial-bus.c index eb7af21a02..a9cb114649 100644 --- a/hw/virtio-serial-bus.c +++ b/hw/virtio-serial-bus.c @@ -579,6 +579,7 @@ static void virtio_serial_post_load_timer_cb(void *opaque) VirtIOSerial *s = opaque; VirtIOSerialPort *port; uint8_t host_connected; + VirtIOSerialPortClass *vsc; if (!s->post_load) { return; @@ -594,6 +595,10 @@ static void virtio_serial_post_load_timer_cb(void *opaque) send_control_event(s, port->id, VIRTIO_CONSOLE_PORT_OPEN, port->host_connected); } + vsc = VIRTIO_SERIAL_PORT_GET_CLASS(port); + if (vsc->set_guest_connected) { + vsc->set_guest_connected(port, port->guest_connected); + } } g_free(s->post_load->connected); qemu_free_timer(s->post_load->timer);
