Abstract
A system includes a memory, at least one processor in communication with the memory, a guest hypervisor, and a host hypervisor executing on the at least one processor. The host hypervisor is configured to receive a request for additional memory, request the additional memory from a paravirtualized memory device, allocate the additional memory to the guest hypervisor, and report a status of the request. The status of the request is either a success status or a failure status.
