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