networks are not specified introduce an error says the NetworkID is needed

[Jeffrey Guan]

Dear all,

when I run the following command to create a stack,
heat stack-create -f test.yaml jeguan

I received the following error:

[root@jeguan]# heat event-list jeguan
| oam_group | 985b0250-f581-49e4-8b3e-934a8c699df2 | Error: Resource CREATE failed: Error: Resource CREATE failed: BadRequest: Multiple possible networks found, use a Network ID to be more specific. (HTTP 400) (Request-ID: req-30534876-6a02-4abf-acc7-e9476df95625) | CREATE_FAILED | 2016-01-27T10:29:32Z |

Some parts of the test.yaml:
  testOAM:
    type: OS::Nova::Server
    properties:
      image: {get_param: image}
      flavor: {get_param: flavor}
      key_name: {get_param: key_name}
      user_data_format: RAW
      user_data: |
        #!/bin/python
        list1={"node1": 1, "node2": 2, "node3": 3}
        for k in list1
          echo list1[k] >> test.out

However, I see some example(https://github.com/double12gzh/demo_templates/blob/master/kilo_summit_heat_beyond_the_basics/example1_provider_environment/server_with_volume.yaml) for OS::Nova::Server shows that the networks are needed.

Thanks,
Jeffrey

I don't think it's a bug, if don't specify the network, nova will choose the 'available' network, but if there are some public or private network the user can see, then nova doesn't know to choose which one, then nova will ask you to specify one.

Thank you so much for your answer.
