Method and system for reading and writing user data under virtual environment and physical machine

Abstract

The embodiment of the invention provides a method and system for reading and writing user data under virtual environment and a physical machine. The method includes the steps that whether every virtual machine has a user data reading and writing request or not is detected; the user data reading and writing requests of all the virtual machines are collected; the reading requests are added into a reading request queue, and the writing requests are added into a writing request queue; when the correspondence degree between first request addresses in the reading request queue and / or the writing request queue and second request addresses in the reading request queue and / or the writing request queue meets a preset condition, the request queue corresponding to the first request address is adjusted according to a request queue adjustment method corresponding to the preset condition; a request in the front of the request queue with the high priority is called and sent to a server where the user data are stored. By means of the method, reading and writing pressure of communication interfaces of the physical machine and the reading and writing pressure of the server where the user data are stored are substantially reduced, and user data reading and writing efficiency is improved.

Description

technical field [0001] The present invention relates to virtualization technology, more specifically, to a method, system and physical machine for reading and writing user data in a virtualized environment. Background technique [0002] At present, virtualization technology is accepted by more and more users. The virtualization referred to here includes end-user-oriented desktop virtualization and service-oriented computing virtualization; virtualization technology can expand the capacity of hardware and simplify software reconfiguration Through virtualization technology, a single CPU (processor) can be simulated as multiple CPUs in parallel, allowing one platform to run multiple operating systems at the same time, such as simulating two or more virtual computers on a physical computer (that is, virtual machine). [0003] There are mainly two different types of data in virtualization application scenarios: system data and user data. System data refers to the data of the op...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the embodiments of the present invention provide a method, system, and physical machine for reading and writing user data in a virtualized environment, so as to solve the problem that the communication interface of the physical machine may be difficult due to the competition between multiple virtual machines for the communication interface of the physical machine. There is a large reading and writing pressure on the server that stores user data, resulting in the problem of low reading and writing efficiency of user data
