That error message is unfortunately misleading (and it has been improved in Icehouse). It appears when the security group is not found in Neutron - I suspect because it requires a UUID instead of a name. (This has also been improved in Icehouse.) So you could try passing a UUID or get_resource on a security group defined in the template.

However the security_groups property is optional, and if you leave it off I imagine the port ends up in the default security group, so just removing it might be the first thing to try.

Hi Zane,

Thanks for the answer . I commented out the security_group , No mu instance creation is successfull.

 instance0_port0:
    type: OS::Neutron::Port
    properties:
      network_id: { get_param: private_net_id }
     # security_groups:
      # OS::Neutron::SecurityGroup
    # - default
need a one more favor from you .. could you pleae refer me the guide from which I can create and understand the templates in heat , So that I can learn to create my own templates.

it will be a great help for me.. Thanks again for your reply :)
