Sorry, the name of the type is incorrect, should be
'types.VmPlacementPolicy'. So the complete example should be like this:

  vm = vms_service.add(
    vm=types.Vm(
      ...
      placement_policy=types.VmPlacementPolicy(

        hosts=[
          types.Host(name='host-01')
        ]
      )
    )
  )
