[libvirt] [PATCH 3/3] Create a console stub for the first serial device
The <console> alias for the first <serial> device was only
formatted when there were no consoles.
After removing this alias manually, a round-trip via XML
would add it again. However this was not the case when
it was removed and a virtio console was hotplugged.
