We are unable to create an instance. We are getting below errors . On the Controller Node: *nova-api.log:* HTTP exception thrown: No instances found for any event HTTP exception thrown: Quota exceeded for instances: Requested 1, but already used 10 of 10 instances

nova-conductor.log NoValidHost: No valid host was found. There are not enough hosts available.

Failed to compute_task_build_instances: No valid host was found. There are not enough hosts available.

nova-compute.log PortBindingFailed: Binding failed for port 41151c02-9e02-49f7-8101-226c2bb3c1a6, please check neutron logs for more information

Hi Megha, 1) This is a very generic log, you need to find out more specific log. Please enable debug logs for nova, add debug=true in /etc/nova/nova.conf and restart the nova-api service and see what exact error you see. 2) I can see nova is failing because there is some error in neutron and its asking you to check neutron logs. "nova-compute.log PortBindingFailed: Binding failed for port 41151c02-9e02-49f7-8101-226c2bb3c1a6, please check neutron logs for more information" So please check your neutron logs for more information. Post your neutron-server logs for that duration.
