Abstract
A system for memory management for Virtual Machines (VMs), including a host computer system running a host operating system (OS); at least two Virtual Machines (VMs) running on the host computer system, wherein each of the VMs has a Guest OS supporting a guest file system with execution-in-place that allows code execution without an intermediate buffer cache; a hypervisor configured to control the VMs; and a thin provisioning block device configured to store shared pages and formed of at least one delta file. The hypervisor is configured to receive a page fault, and to read the shared pages from the thin provisioning block device. The Guest OS executes the file that is stored on the thin provisioning block device.
