Re: [libvirt] [PATCHv2] Always add 'console' matching the 'serial' device

We have been formatting the first serial device also as a console device, but only if there were no other consoles. If there is a <serial> device present in the XML, but no serial <console>, or if there isn't any <console> at all but the domain definition hasn't gone through a parse->format->parse round-trip, the <console> device would not be formatted. Change the code to always add the stub device for the first serial device.
