25 This is thread that interacts with a VIM. It processes TASKs sequentially against a single VIM.
26 The tasks are stored at database in table vim_actions
27 The task content is (M: stored at memory, D: stored at database):
28 MD instance_action_id: reference a global action over an instance-scenario: database instance_actions
29 MD task_index: index number of the task. This together with the previous forms a unique key identifier
30 MD datacenter_vim_id: should contain the uuid of the VIM managed by this thread
31 MD vim_id: id of the vm,net,etc at VIM
32 MD action: CREATE, DELETE, FIND
33 MD item: database table name, can be instance_vms, instance_nets, TODO: datacenter_flavors, datacenter_images
34 MD item_id: uuid of the referenced entry in the previous table
35 MD status: SCHEDULED,BUILD,DONE,FAILED,SUPERSEDED
36 MD extra: text with yaml format at database, dict at memory with:
37 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
38 find: (only for CREATE tasks) if present it should FIND before creating and use if existing. Contains the FIND params
39 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
40 sdn_net_id: used for net.
42 interfaces: used for VMs. Each key is the uuid of the instance_interfaces entry at database
43 iface_id: uuid of intance_interfaces
46 created_items: dictionary with extra elements created that need to be deleted. e.g. ports, volumes,...
47 created: False if the VIM element is not created by other actions, and it should not be deleted
48 vim_status: VIM status of the element. Stored also at database in the instance_XXX
49 M depends: dict with task_index(from depends_on) to task class
50 M params: same as extra[params] but with the resolved dependencies
51 M vim_interfaces: similar to extra[interfaces] but with VIM information. Stored at database in the instance_XXX but not at vim_actions
52 M vim_info: Detailed information of a vm,net from the VIM. Stored at database in the instance_XXX but not at vim_actions
53 MD error_msg: descriptive text upon an error.Stored also at database instance_XXX
54 MD created_at: task creation time
55 MD modified_at: last task update time. On refresh it contains when this task need to be refreshed
