If you want to avoid ballooning failures, the option may be useful, but as
long as your dom0 doesn't really allocate all that memory (so that the
balloon driver can't grab it anymore) there should be no problem omitting
it. (256Mb for dom0 would be questionable at least - I'd certainly not set it
to this small a value.)
