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".
