Hi Mel,

Thank you for your response.

I am facing issues with the instance console (vnc) in the openstack dashboard, Most of the time I shelve the instance and unshelve the instance to get the console.

But there are some VM's I created which are not working even after shelve/unshelve.

I have used the same director to deploy a total of a central and 2 edge sites.

This issue is happening on a single edge site.

Cold Migration also helps in some situations.

With regards,

Swogat Pradhan

When you say "instance console" are you referring to an interactive
console like VNC or are you talking about the console log for the instance?

If it's the interactive console, if you have a console open and then
migrate the instance, that console will not be moved along with the
instance. When a user requests a console, the console proxy service
establishes a connection to the compute host where the instance is
located. The proxy doesn't know when an instance has been moved though,
so if the instance is moved, the user will need to request a new console
(which will establish a new connection to the new compute host).

Is that the behavior you are seeing?
