<div>I am assuming source mode is for the host. Bind means server and connect would mean client.</div>
<div><br>
</div>
<div>The other part is still pending.</div>
<div>On host, when I run cat it gives no such device or address </div>
<div><br>
</div>
<div>Or a python program to bind the socket (in my case /tmp/appl_port) it gives </div>
<div>'unable to connect to virtio-serial port. Error: %s', error(111, 'Connection refused'))</div>
<div><br>
</div>
<div>Am I missing something?</div>

<div>Hi All,</div>
<div> 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</div>
<div><br>
</div>
<div>
<div> <channel type='unix'></div>
<div> <source mode='bind' path='/tmp/appl_port'/></div>
<div> <target type='virtio' name='appl_port'/></div>
<div> <address type='virtio-serial' controller='0' bus='0' port='1'/></div>
<div> </channel></div>
</div>
<div><br>
</div>
<div>When I see on the host, the unix socket is already binded and is in listening state.</div>
<div><br>
</div>
<div>
<div>echo "test this" > /tmp/appl_port</div>
<div>bash: /tmp/appl_port: No such device or address</div>
</div>
<div><br>
</div>
<div>
<div>netstat -nax | grep appl_port</div>
<div>unix 2 [ ACC ] STREAM LISTENING 15302258 /tmp/appl_port</div>
</div>
<div><br>
</div>
<div>1) Can some one please have a look and help me fix this.</div>
<div>2) if I don't set source mode to 'bind', it gets set to 'connect' in xml and VM fails to boot up. I would like to understand the different types of source mode.</div>
<div>Dmesg shows below denied message for connect mode.</div>
