Abstract

Virtual machines are managed by obtaining software hierarchy information of a current virtual machine to be installed. Then logical memory assigned to the current virtual machine is divided into a private part and a shared part based at least in part upon existing software hierarchy information of at least one virtual machine already installed and the software hierarchy information of the current virtual machine. Then, the shared part of the logical memory is mapped to shared segments of a physical memory, wherein the shared segments are used by at least one installed virtual machine.

Description

technical field [0001] The present invention relates to a virtual machine, and more specifically, to a device and a method for managing a virtual machine. Background technique [0002] Recently, virtualization technology has been widely used in various application environments to improve the efficiency of IT resources and applications. Virtualization technology can allocate resources, applications and even servers to corresponding locations at any time according to needs, thereby integrating resources and improving computer availability, thereby saving 50% to 70% of total IT costs. [0003] A typical implementation of virtualization is to simulate one or more virtual computers on a physical computer, that is, a virtual machine (Virtual Machine), which is simulated by software with complete hardware system functions and runs in a completely isolated environment. A complete computer system in . Such a virtual machine, like a physical computer, carries its own guest operating...
