I followed https://docs.openstack.org/ocata/install-guide-ubuntu/ (OpenStack Installation Tutorial for Ubuntu) to install openstack in Ubuntu with one controller node and one compute node. After I installed Keystone, Glance, Nova, Neutron, and Horizon step by step, I launched an instance but failed. It stucked in scheduling for 17 hours+. I want to known how to debug and solve this problem. Thank you, my friends.

The log in controller: http://paste.openstack.org/show/601934/ (nova-api) http://paste.openstack.org/show/601935/ (nova-conductor) http://paste.openstack.org/show/601936/ (nova-scheduler)

The log in compute: http://paste.openstack.org/show/601937/ (nova-compute)

You have this error in the API log: "No cells are configured, unable to list instances". Could it be that the VM is running but Nova can't list it correctly? Check on the compute node.

Ocata Nova requires a single cell setup. I can't tell why you have no cells.

The other problem: placement API doesn't seem to be configured, so it seems that the compute node can't register its resources. Thus I guess no host found for scheduling. Placement API info.

This might be due to a problem with the installation guides: https://bugs.launchpad.net/openstack-....

I had that problem; it was the install doc bug. I did a new ubuntu build today following the updated install docs (marked UPDATED: 2017-03-27) and it works. There is a packaging dashboard error. Do a "# chown www-data:www-data /var/lib/openstack-dashboard/secret_key ; service apache2 restart".

Exactly the same problem here !! (Ubuntu 16.04 LTS + Ocata)
