- 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
