From: Archana Singh <archus(a)linux.vnet.ibm.com&gt; Socket server gets closed for VM's serial console connection if its not readable instead writeable. This is due to fact that _is_vm_listening_serial(...) only call _test_output if its readable and not on writeable. Adding libvirt.VIR_STREAM_EVENT_WRITABLE solve the issue. Also added libvirt.VIR_STREAM_EVENT_HANGUP event so that in case of hangup also console gets connected.

Hi Archana, With this patch, the test_model hangs and I need to kill the process.
