Hi All,
  My intent is to make virtio unix channel work. I could configure the
XML and launch VM and could see the port in /dev/virtio-ports
    <channel type='unix'>
      <source mode='bind' path='/tmp/appl_port'/>
      <target type='virtio' name='appl_port'/>
      <address type='virtio-serial' controller='0' bus='0' port='1'/>
    </channel>
When I see on the host, the unix socket is already binded and is in
listening state.
echo "test this" > /tmp/appl_port
bash: /tmp/appl_port: No such device or address
Try this:

   echo "test this" | socat - UNIX-CONNECT:/tmp/appl_port

You can't write to socket files the way you write to normal files.
