+config XEN_BALLOON
+        bool "Xen memory balloon driver"
+        depends on XEN
+        default y
+        help
+          The balloon driver allows the Xen domain to request more memory from
+          the system to expand the domain's memory allocation, or alternatively
+          return unneeded memory to the system.

+config XEN_SCRUB_PAGES
+        bool "Scrub pages before returning them to system"
+        depends on XEN_BALLOON
+        default y
+        help
+          Scrub pages before returning them to the system for reuse by
+          other domains.  This makes sure that any confidential data
+          is not accidentally visible to other domains.  Is it more
+          secure, but slightly less efficient.
+          If in doubt, say yes.
