Abstract
Techniques are described for enabling a virtual machine to be presented with an amount of available guest memory, where a hypervisor or other privileged component manages the mapping of the guest memory to either volatile memory (e.g., RAM) or to secondary storage (e.g., SSD). This enables volatile memory to be effectively oversubscribed to on host computing devices that have a limited amount of total available volatile memory but which are running multiple virtual machines. For example, each virtual machine on the device can be presented as having access to the total amount of available RAM that is available on the device. The hypervisor or other virtualization component then monitors the usage of the memory by each virtual machine and shapes which portions of the guest memory for that virtual machine are mapped to RAM and which portions are mapped to secondary storage, such as SSD.
