Cloning virtual machine

Workflow clone_vm defines the process of creating a new VM based on existing VM which was created using bootable volume (and may have other additional volumes). It's also a good example of using sub-workflows in one workflow.

To run the example:

1. Create sub-workflows clone_volume.yaml and boot_vm_from_volume.yaml:

   mistral workflow-create clone_volume.yaml
   mistral workflow-create boot_vm_from_volume.yaml

2. Create workflow clone_vm.yaml:

   mistral workflow-create clone_vm.yaml

3. Create input.json file containing workflow input parameters as follows:

   {
     "vm_name": "new_vm",
     "flavor_ref": "1",
     "source_root_vol_id": "1969299a-4c45-4900-bfe0-5ac65c1f2211",
     "root_vol_name": "new_root_vol",
     "root_vol_size": 1,
     "additional_volumes": [
       {
         "vol_name": "new_user_vol_1"，
         "vol_size": 1,
         "source_vol_id": "94391f69-a2f7-4406-b602-86e0b421d519"
       },
       {
         "vol_name": "new_user_vol_2"，
         "vol_size": 1,
         "source_vol_id": "262b37ab-86f1-4be5-ada2-645898400584"
       }
     ]
   }

4. Start workflow:

   mistral execution-create clone_vm input.json

5. Get execution status by using execution id from the previous command output:

   mistral execution-get <execution_id>

6. Make sure that a virtual machine with a bootable volume and two additional volumes has been created successfully. It can be done by opening Horizon UI or using Nova client (python-novaclient).
