These days, I have focused on deploying a cluster with 1 controller node and 1 compute node. When following the steps in Launch an instance part of openstack install-guide-rdo, I can't launch the instance of cirros. Here are some import logs from my controller node and compute node.

/* nova-compute.log on compute node*/

NoValidHost: No valid host was found. There are not enough hosts available.

I am pretty confused with the error, and google even can't give me an answer. Please someone who can tell how to get it work?

P.S. All the configurations is the same to, and I use two CentOS 7 virtual machines to deploy controller node and compute node.

It sounds that policy.json in Nova does not allow you to create port on external network So: -are you using Keystone admin user? -can you create new Neutron network (not external one) and try to boot VM using that one? -yeah, check /etc/nova/policy.json

I haven't changed the /etc/nova/policy.json, so it's empty. Does it matters?

Well, after I have changed the neutron.conf, the instance finally stared. So ... what is the reason?

/* neutron.conf */
auth_strategy = noauth


Oh my, I finally address it. After reviewing my nova configuration carefully several times, I found that something important is missed...

When Nova has problems with ports, I would search the neutron server log for the port ID.
