-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 is (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 together with the previous forms a unique key identifier
- 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 previous 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- MD status: SCHEDULED,BUILD,DONE,FAILED,SUPERSEDED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 creation depends on a net creation
- 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_items: dictionary with extra elements created that need to be deleted. e.g. ports, volumes,...
- 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
