  53           Limit paravirtualized user domains to 512GB of RAM.
  54
  55           The Xen tools and crash dump analysis tools might not support
  56           pv-domains with more than 512 GB of RAM. This option controls the
  57           default setting of the kernel to use only up to 512 GB or more.
  58           It is always possible to change the default via specifying the
  59           boot parameter "xen_512gb_limit".
