Mostly a docs issue. The <console> element is defined to refer to the
first text console available for the guest. For Xen paravirt, this is
the xen xvc0/hvc0 paravirt console. For Xen/QEMU fullyvirt guests this
is currently defined to be the first serial port. In the very near
future I will make it possible to override this behaviour, ostensibly
to let us use VirtIO console. I hadn't considered the case that someone
might want to make the <console> match the secondary serial port, but
if practical I can try and make that work.
