I installed devstack and trying to create stack with 'wordpress' template(same URL for both fields) " https://raw.githubusercontent.com/openstack/heat-templates/master/hot/F20/WordPress_2_Instances.yaml%22 (https://raw.githubusercontent.com/ope...) (using dashboard). but I got stack creation status "failed" for the reason "No valid host was found".I thought that it came for not enough memory so changed flavor to (tiny to)medium.But I got same error. plz guide me how to resolve the issue.

Thanks
