There seem to be a coupe of other questions around this but no answers, so I'll ask as well.
I installed Openstack Juno via Landscape Autopilot and the Openstack Horizon dashboard shows all compute, storage and networking services active.
When I launch an instance within a project (any project, including admin) I eventually get an error, example below:
Error: Failed to launch instance "docker_test": Please try again later [Error: No valid host was found. Exceeded max scheduling attempts 3 for instance 34722fff-8e59-47a0-898d-853a5d3c8dd8. Last exception: [u'Traceback (most recent call last):\n', u' File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 2039, in _do].
I don't really know where to start with this. Any ideas?
