Title:
  Powervm driver does not support IBM i

Status in OpenStack Compute (Nova):
  Confirmed

Bug description:
  Rationale:
      Currently OpenStack does not support IBM i in powervm driver. Although the underground virtualization mechanism of IBM i is the same as current supported PowerLinux in PowerVM, IBM i instances can not be deployed correctly.

  Overview:
      To support IBM i in powervm, the implementation of the enhancement will be based on current powervm implementation, which includes IVM managed system, single VIOS support and logical volume support. It enrolls a difference in image meta to distinguish IBM i image and Power Linux/AIX. PowerVM will distinguish OS type based on image meta to generate partition accordingly.

  Use Cases:
       1. Create new IBM i instance based on file-based IBM i image.
       2. Start IBM i instance.
       3. Stop IBM i instance.
       4. Create snapshot on a IBM i instance.
       5. Delete an IBM i instance.

  Design:
      The changes for IBM i supporting are within powervm of Nova, which may include:
       1. Specify partition property lpar_env for IBM i instance.
       2. Specify partition property ipl_source as b for IBM i instance.
       3. Specify LPA_PROFILE_ATTRIBUTES load_source_slot and console_slot for IBM i instance.
       4. Specify partition keylock position as norm during powering on IBM i instance.
       5. Check lpar_started status for IBM i instances according to refcode and running state.
