792 | to reduce the memory size of the system. This is accomplished | |
793 | by allocating pages of memory and put them "on hold". This only | |
794 | makes sense for a system running under VM where the unused pages | |
795 | will be reused by VM for other guest systems. The interface | |
796 | allows an external monitor to balance memory of many systems. | |
797 | Everybody who wants to run Linux under VM should select this | |
798 | option. | |
