Hello everyone. I'm having trouble creating an instance on Openstack Pike. All the services responsible for creating the instances are "UP", but when I run the "openstack server create" the instances get the error status ... When I run "openstack server show" + the name of the newly created instance, field "fault" I get the following error:

{u'message ': u'No valid host was found. ', u'code': 500, u'created ': u'2018-11-10T15: 04: 05Z'}

Does anyone have any idea what's going on?

Thank's for the attention of the community.

It means that none of your compute hosts has sufficient resources to run the instance, or the right architecture, or other properties imposed by the flavor and the image metadata. You may find details in the log files for the placement service and the nova-scheduler, in particular if debug loggin is enabled.

A common problem is unability of compute nodes to register with the Placement service. Run the command nova-status upgrade check to see if this is the case.

I have this result: Check: Resource Providers Result: Warning
Details: There are no compute resource providers in the Placement service but there are 2 compute nodes in the deployment. This means no compute nodes are reporting into the Placement service and need to be upgraded and/or fixed.
