Help creating instance in Openstack Dashboard

I have Open-Stack with Red Hat Linux. In the Dashboard, when I create an instance from an image or a volume, I get an error: task status not updating and stating at "scheduling", or "local host not found". Can you help resolve the problem and provide the detailed procedure to create an instance? Thanks!
