Re: [libvirt-users] virtio channel socket bind error

I got this working. I have to treat the port as char device on guest and unix socket on the host and that too as client. Thanks, -Ravi.

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, -Ravi.

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. 84616.025345] type=1400 audit(1380129082.835:210): apparmor="DENIED" operation="capable" parent=1 profile="/usr/sbin/libvirtd" pid=9804 comm="libvirtd" pid=9804 comm="libvirtd" capability=29 capname="audit_write" Thanks, -Ravi.
