Open Stack

I've got the same problem.

When I try to connect to the instance using VNC through the dashboard, 
I've got this error. I then went in /var/log/nova/nova-xvpvncproxy.log 
and it contains nothing related to any attempt to get connected to any 
instance. It seems this nova-xvpvncproxy process doesn't notice anything.


When I try to connect using VNC through virt-manager, it works.
