"no valid host was found" can mean that (a) your compute nodes are not properly registered with your controller, or (b) that you are trying to start an instances that requirements more resources (e.g., memory, cpu, disk) than are available in your environment...
What is the output of
nova service-liston your system (you must run this command with admin credentials)?I've seen such message, when the provisioned instance requires too many resources, that obviously not always available on any of compute nodes.
when i run
nova service-listit lists below nova-conductor, nova-cert,nova-scheduler, nova-consoleauth, nova-compute with status enabledI am unable to put all data here as comment.
I have enough resources to launch a instance. I dont think problem with resources
