That doesn't make sense to me. virtio channel can have a name, but
isa serial cannot, that name wouldn't make sense.
That's the reason why libvirt just doesn't deal with isa-serials as an
interface to guest agent. My point is, we need a way in a array of
<serials/> to find the correct one that qemu-ga is going to listen to.
Also, how would you
identify to which serial port to attach in the guest-agent?
Right now, qemu-ga has -p switch, that allows you to pass the path it
should listen to. In this case:
qemu-ga -m isa-serial -p /dev/ttyS0
should do. I'm no *BSD-ian, but I bet it can be configured in their
startup scripts.
So the only question is, how to mark the correct <serial/> in the domain
XML.
