| 57 | Limit paravirtualized user domains to 512GB of RAM. |
| 58 | |
| 59 | The Xen tools and crash dump analysis tools might not support |
| 60 | pv-domains with more than 512 GB of RAM. This option controls the |
| 61 | default setting of the kernel to use only up to 512 GB or more. |
| 62 | It is always possible to change the default via specifying the |
| 63 | boot parameter "xen_512gb_limit". |
