Abstract
A system includes at least one memory device, at least one processor in communication with the at least one memory device, a guest operating system (OS) associated with a device driver, and an out-of-memory (OOM) handler executing on the at least one processor. The OOM handler is configured to locate a memory device of the at least one memory device, send an out-of-memory request to the device driver that is associated with the memory device, and receive a response from the memory device. The device driver is configured to query an amount of unusable device memory, request to plug the unusable device memory, and report the previously unusable device memory as now usable memory.
