Hi all-

I'm trying to run some examples from mistral-extral in order to demo Mistral functionality to my team. I'm using Mistral 0.1.1 cloned from GitHub on Oct 27th 2014.

I'm attempting to run the nova_actions example under mistral-extra/examples/v2/openstack by doing the following:

Create workbook:

mistral workbook-create nova_actions.yaml

Create a context.json file with the following contents:

{
   "vm_name": "mistral-vm",
   "image_ref": "098d6493-b47f-4e9b-a5d2-dae38b1eecc3",
   "flavor_ref": "3",
   "nics": ["e05abe4f-5279-4970-8403-7f9296c306d2"]
}

Create execution:

mistral execution-create nova_actions.create_vm context.json

This command successfully returns to show that the execution is running, but it quickly fails with the following log messages: paste.openstack.org/show/135410

I can see no errors in nova logs. As a matter of fact, I'm not seeing calls pertaining to this tasks showing up in nova-api log.

Here is my workbook definition as defined by nova_action.yaml:

---
version: '2.0'

name: nova_actions

workflows:
  create_vm:
    type: direct
    input:
      - vm_name
      - image_ref
      - flavor_ref
      - nics
    output:
      vm_id: $.vm_id

    tasks:
      create_server:
        action: nova.servers_create name={$.vm_name} image={$.image_ref} flavor={$.flavor_ref} nics={$.nics}
        publish:
          vm_id: $.id
        on-success:
          - check_server_exists

      check_server_exists:
        action: nova.servers_get server={$.vm_id}
        publish:
          server_exists: True
        on-success:
          - wait_instance

      wait_instance:
        action: nova.servers_find id={$.vm_id} status='ACTIVE'
        policies:
          retry:
            delay: 5
            count: 15

My environment variables are set as the following:
