This is thread that interacts with a VIM. It processes TASKs sequentially against a single VIM. |
| 22 |
|
The tasks are stored at database in table ro_tasks |
| 23 |
|
A single ro_task refers to a VIM element (flavor, image, network, ...). |
| 24 |
|
A ro_task can contain several 'tasks', each one with a target, where to store the results |
