Openstack : Unable to connect to instance console at port 6080

I have a VM on virtualbox which acts as an all-in-one Openstack setup. When I spawn a VM on it the VM boots up fine but from the browser I am not able to access its console.

There are various ways to solve this issue:

1. In the latest version of devstack (as on February 2015) n-novnc is no longer a default service and needs to be added to the local.conf to enable it.
enabled_services=n-novnc  (

2. See if this helps you in tweaking manually :

3.Another geeky solution is that, you can grep the KVM process to figure out the port on which the VNC is getting channeled to and access the console.

Now use a VNC client and connect to with credentials cirros/cubswin:) you should be able to see the console.

Extra Info:
If you want to connect to the console from your host rather than from the guest, then you can use port forwarding feature of virtualbox. This youtube video proposes a solution at around 12 mins.
