balloon/hotplug_unpopulated
|
|
===========================
|
|
|
|
This flag controls whether unpopulated memory ranges are automatically
|
|
hotplugged as system RAM.
|
|
|
|
- ``0``: Unpopulated ranges are not hotplugged (default).
|
|
- ``1``: Unpopulated ranges are automatically hotplugged.
|
|
|
|
When enabled, the Xen balloon driver will add memory regions that are
|
|
marked as unpopulated in the Xen memory map to the system as usable RAM.
|
|
This allows for dynamic memory expansion in Xen guest domains.
|
|
|
|
This option is only available when the kernel is built with
|
|
``CONFIG_XEN_BALLOON_MEMORY_HOTPLUG`` enabled.
