Abstract
A virtual machine memory overcommit system includes an initialization memory, a device memory, at least one processor in communication with the initialization memory and the device memory, a guest operating system (OS) including a device driver, and a hypervisor executing on the at least one processor. The hypervisor is configured to expose the initialization memory to the guest OS of a virtual machine, initialize the guest OS, and expose the device memory to the guest OS. The device driver is configured to query an amount of memory available from the device memory and report the amount of memory available to the guest OS.
