A method, system, and physical machine for reading and writing user data in a virtualized environment

Abstract

Embodiments of the present invention provide a method, system, and physical machine for reading and writing user data in a virtualized environment, wherein the method includes: detecting whether each virtual machine has a user data read and write request; collecting the user data read and write requests of each virtual machine, Add the read request to the read request queue, and add the write request to the write request queue; when the correspondence between the first request address and the second request address in the read request queue and / or write request queue meets the preset condition , adjust the request queue corresponding to the first request address according to the request queue adjustment method corresponding to the preset condition; call the previous request in the request queue with relatively high priority, and send the called request to the server storing user data request. The embodiment of the present invention greatly reduces the reading and writing pressure of the communication interface of the physical machine and the server storing user data, and improves the reading and writing efficiency of user data.

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
