Hi, Thx for your hint. I've tried this instead : <channel type='unix'> <source mode='bind' path='/opt/omnivision_1.agent'/> <target type='virtio' name='omnivision_1.agent'/> <address type='virtio-serial' controller='0' bus='0' port='2'/> </channel> Then, when starting the Guest I get a pop up window showing this error message : Error starting domain : internal error : process exited while connecting to monitor Quemu-kvm –chardev socket id=channel1,path=/opt/omnivision_1_agent,server,nowait Failed to bind socket : Permission denied
Did I miss something ?

A channel with that name is special. It's guest agent socket that libvirt automatically connects to once domain is starting up. You need to provide a different name and everything should just work.
