Abstract

The invention provides a management device and method for a virtual machine. The management device comprises a virtual machine information acquisition unit, a memory analyzing unit and a memory mapping unit, wherein the virtual machine information acquisition unit is configured to acquire software hierarchy information of the current virtual machine, the memory analyzing unit is configured to divide a logic memory distributed to the current virtue machine into a special part and a shared part with reference to existing software hierarchy information of at least one installed virtual machine and the software hierarchy information of the current virtual machine, the memory mapping unit is configured to map the shared part to a shared section of a physical memory, and the shared section is used by the at least one installed virtual machine. The invention also provides a management method corresponding to the management device. According to the management device and method provided by the invention, a plurality of virtual machines on the same physical platform can share part of a memory, so that relative independence and isolation of the virtual machines can be maintained at the same time while memory resources are effectively utilized.

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...
