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

Subject: [libvirt-users] virtio channel socket bind error
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
netstat -nax | grep appl_port
unix 2 [ ACC ] STREAM LISTENING 15302258 /tmp/appl_port
1) Can some one please have a look and help me fix this.
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.
Dmesg shows below denied message for connect mode.
