Title:
  Instance action event for live-migration is missing

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  We have the instance action and action event for most of the instance
  operations, exclude: live-migration. In the current master code, when
  we do live-migration, the instance action is recorded, but the action
  event for live-migration is lost.

  Version: Master

  Bug Details:

  Migrate the server:

  After Live-Migrate, the instance action has been recorded but the action event is missing:
