In the latest devstack (pulled on 7/3/14), you cannot access an instance's noVNC console on the horizon dashboard after you launched the instance. If you look at the logs, you will find:

This was noted in the following forum post: https://ask.openstack.org/en/question/33966/vnc-in-the-dashbaord-says-failed-to-connect-to-server-code-1006-the-set-up-is-by-devstack-on-ubuntu-1204-with-kvm/
The problem is in line 228:
instance.info_cache = objects.InstanceInfoCache(context)
It should be corrected to:
from nova.objects import instance_info_cache
...
instance.info_cache = instance_info_cache.InstanceInfoCache(context) |
