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