When you start your domain and then dump its XML it will look like this:
<channel type='pty'>
<source path='/dev/pts/12'/>
<target type='virtio' name='arbitrary.virtio.serial.port.name'/>
<alias name='channel0'/>
<address type='virtio-serial' controller='0' bus='0' port='2'/>
</channel>
So one end of the channel is inside the domain under
/dev/virtio-ports/arbitrary.virtio.serial.port.name and the other one is
under /dev/pts/12 in the host. Therefore running:
(guest) cat /dev/virtio-ports/arbitrary.virtio.serial.port.name
(host) echo "Hello world" > /dev/pts/12
will do all the magic. You can use any tool that is able to work with
unix domain sockets. I personally use socat [1].
