fred.konrad@greensocs.com - Jan. 7, 2013, 6:41 p.m.
From: KONRAD Frederic <fred.konrad@greensocs.com>

Here the virtio-serial-s390 is modified for the new API. The device
virtio-serial-s390 extends virtio-s390-device as before. It creates and
connects a virtio-serial during the init. The properties are not
modified.
