Abstract
A system memory is partitioned into a first paged partition for a first operating system and a second paged partition for a second operating system. The first paged partition is mapped into a first virtual memory partition, and the second paged partition is mapped into a second virtual memory partition. A subset of pages within the second virtual memory partition is marked as reclaimable by the first operating system to produce a set of marked pages. Responsive to a request by the first operating system for further memory, at least one reclaimable page selected from the set of marked pages is swapped out to a storage file, and the first operating system writes to the at least one reclaimable page.
