| 32 | Limit paravirtualized user domains to 512GB of RAM. | |
| 33 | ||
| 34 | The Xen tools and crash dump analysis tools might not support | |
| 35 | pv-domains with more than 512 GB of RAM. This option controls the | |
| 36 | default setting of the kernel to use only up to 512 GB or more. | |
| 37 | It is always possible to change the default via specifying the | |
| 38 | boot parameter "xen_512gb_limit". | |
