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". |
