Abstract
Memory assigned to a virtual machine is reclaimed. A resource reservation application running as a guest application on the virtual machine reserves a location in guest virtual memory. The corresponding physical memory can be reclaimed and allocated to another virtual machine. The resource reservation application allows detection of guest virtual memory page-out by the guest operating system. Measuring guest virtual memory page-out is useful for determining memory conditions inside the guest operating system. Given determined memory conditions, memory allocation and reclaiming can be used control memory conditions. Memory conditions in the virtual machine can be controlled with the objective of achieving some target memory conditions.
