[libvirt-users] Using unix-type channel ....

[Jean-Pierre Ribeauville]

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 ?

Regards,

J.P.

This won't fly. 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.
