Title:
  many codepaths do not pass image_meta to libvirt blockinfo APIs

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  This bug reported a problem with the finish_migration method not
  passing image_meta to the libvirt blockinfo APIs

  https://bugs.launchpad.net/nova/+bug/1389850

  On closer inspection there are a great many codepaths which don't pass
  image_meta to the libvirt blockinfo APIs. Essentially every single one
  of these is a bug which needs fixing, otherwise the user requested
  disk bus will not be honoured in those scenarios.

  The best fix is to stop making the image_meta parameter be optional,
  with a None default. Make it compulsory and do not provide a default
  value. This way all callers are forced to pass it, which should reduce
  the scale of the problem
