| This is thread that interacts with a VIM. It processes TASKs sequentially against a single VIM. |
| The tasks are stored at database in table vim_actions |
| The task content are (M: stored at memory, D: stored at database): |
| MD instance_action_id: reference a global action over an instance-scenario: database instance_actions |
| MD task_index: index number of the task. This with the previous are a key |
| MD datacenter_vim_id: should contain the uuid of the VIM managed by this thread |
| MD vim_id: id of the vm,net,etc at VIM |
| MD action: CREATE, DELETE, FIND |
| MD item: database table name, can be instance_vms, instance_nets, TODO: datacenter_flavors, datacenter_images |
| MD item_id: uuid of the referenced entry in the preious table |
| MD status: SCHEDULED,BUILD,DONE,FAILED,SUPERSEDED |
| MD extra: text with yaml format at database, dict at memory with: |
| params: list with the params to be sent to the VIM for CREATE or FIND. For DELETE the vim_id is taken from other related tasks |
| find: (only for CREATE tasks) if present it should FIND before creating and use if existing. Contains the FIND params |
| depends_on: list with the 'task_index'es of tasks that must be completed before. e.g. a vm depends on a net |
| sdn_net_id: used for net. |
| tries: |
| interfaces: used for VMs. Each key is the uuid of the instance_interfaces entry at database |
| iface_id: uuid of intance_interfaces |
| sdn_port_id: |
| sdn_net_id: |
| created: False if the VIM element is not created by other actions, and it should not be deleted |
| vim_status: VIM status of the element. Stored also at database in the instance_XXX |
| M depends: dict with task_index(from depends_on) to task class |
| M params: same as extra[params] but with the resolved dependencies |
| M vim_interfaces: similar to extra[interfaces] but with VIM information. Stored at database in the instance_XXX but not at vim_actions |
| M vim_info: Detailed information of a vm,net from the VIM. Stored at database in the instance_XXX but not at vim_actions |
| MD error_msg: descriptive text upon an error.Stored also at database instance_XXX |
| MD created_at: task creation time |
| MD modified_at: last task update time. On refresh it contains when this task need to be refreshed |
