The ``-I (--default-iallocator)`` option specifies the default
334
instance allocator. The instance allocator will be used for
335
operations like instance creation, instance and node migration,
336
etc. when no manual override is specified. If this option is not
337
specified, the default instance allocator will be blank, which
338
means that relevant operations will require the administrator to
339
manually specify either an instance allocator, or a set of nodes.
