Again, the error message could use improvement, say "machine does not
support hot-plugging CPUs".

I can't help to wonder why this is an error, though.  What's the
difference to successfully returning an empty list?  David, you added
the command, can you explain?

By the way:

    ##
    # @query-hotpluggable-cpus:
    #
    # TODO: Better documentation; currently there is none.

The TODO is three years old, and the command four.  Can we resolve it,
please?
