[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. 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.
