    migration volume failed for invalid type
    
    Boot an instance from image (create a new volume), then migrate this
    volume. When migrating, source_type and destination_type will be
    checked for validity at function
    nova.virt.block_device.DriverVolumeBlockDevice._transform().
    The valid source is volume. But source_type is
    not volume, is image in the block_device_mapping table. It causes
    migration failure.
    Actually source_type may be image snapshot and volume. At
    swap_volume, it should call the convert_volume, but not
    DriverVolumeBlockDevice.

Title:
  in-used volume can't be migrated for InvalidType

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Reproduction steps：
  1. Boot instance from image (create a new volume) , Instance spawned successfully.
  cli command:
  nova boot --flavor 1 --block-device id=b171c0ba-0532-4e38-be4d-05c291e88403,source=image,dest=volume,bootindex=0,size=20 --nic net-id=e499cc2e-c6bb-4d70-9fe8-616f5399bf49  vm1

  In the cmd，b171c0ba-0532-4e38-be4d-05c291e88403 is an image.

  2. Migrate/Retype the volume which created by step 1.
  cli command:
  cinder migrate <volume-uuid> <dest-volume-host>
  Or cmd:
  cinder retype <volume-uuid> <another-type> on-demand

  3.The volume migrate/retype failed

  4.Get error infomation in nova-compute.log :
