Virtualization method, apparatus and system

Abstract

Embodiments of the invention provide a virtualization method, apparatus and system, which realizes hardware virtualization. The method comprises the steps of generating a data access message, wherein the data access message carries a virtual machine identifier and virtual address information, the virtual machine identifier is used for identifying a virtual machine which generates the data access message, and the virtual address information is a virtual address of to-be-accessed data in the virtual machine; sending the data access message to a memory controller; and determining a physical memory address of the to-be-accessed data in a memory device according to the virtual machine identifier and the virtual address information by the memory controller. By adding the virtual machine identifier to the data access message, direct access to memory resources is realized, a tedious management process of memory resource access by software in the virtualization system is removed, and a base is provided for dynamic allocation of virtual machine resources.

Description

technical field [0001] The embodiments of the present invention relate to the computer field, and in particular, to a virtualization method, device and system. Background technique [0002] At present, there are various loads in the data center, and it is difficult for a single hardware structure to meet the demands of diverse loads efficiently and at low cost. In order to efficiently use data center resources, it is necessary to maximize the dynamic allocation of all hardware resources of data center servers. Virtualization Technology (Virtualization Technology, VT) is a main technology that can make full use of hardware resources. [0003] Virtualization technology refers to the ability to virtualize a set of hardware into multiple sets of hardware on a complete computer hardware platform, and provide them to multiple independently running software systems (usually operating systems, such as Windows, Linux, Unix, Mac, etc.) as an independent operating environment, these ...

AI Technical Summary

Problems solved by technology

[0004] At present, most virtualization technologies realize system-wide virtualization through software, resulting in unsatisfactory virtual machine performance.

For example, the virtualization of the processor is realized through the task scheduling of the VMM, and each virtual machine switch will bring a certain performance loss; Buffer, TLB) is missing, resulting in system performance loss, and the memory controller cannot perceive the virtual machine, making it difficult to optimize memory access scheduling according to the virtual machine
