A remote mirror file transmission method, device and system

Abstract

The embodiment of the invention discloses a remote transmission method, device and system for a mirror image file. The method comprises the following steps: creating remote communication connection with a browser, receiving attribute information through the communication connection, wherein the attribute information is attribute information of a local file of the browser, simulating according to the attribute information to obtain a disk mirror image file, after receiving a disk read-write request to the disk mirror image file from a virtual machine, converting the disk read-write request into a file read-write request, transmitting the file read-write request to the browser through the communication connection, receiving the read-write result data fed back by the browser through the communication connection, and feeding back the read-write result data to the virtual machine. During the whole process, the communication function of the browser is utilized, a novel protocol demand is not required to be added, and authorization operation of a user to the simulated disk mirror image file is not required, so that the transmission operation can be simplified, and the requirement for the communication protocol can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for transmitting remote image files Background technique [0002] A disk image (image) file is a separate file that stores all the data content and data structure representing a storage medium or device, and copies the source storage medium sector-to-sector, so the data structure and data content of the device can be copied . A remote image file is also a disk image file. Compared with a local disk image file, a remote image file refers to a form in which the actual location of the disk image file is not in the local area. A CD image file is a specific form of a disk image file. [0003] A virtual machine (Virtual Machine, VM) is one or more virtualized computer systems divided on a physical device. A virtual machine monitor (Virtual Machine Monitor, VMM) is a program that controls a virtual machine in a virtual environment and provid...

Problems solved by technology

[0007] Using the CIFS protocol to mount remote files to the local solution requires the cloud management system to support the CIFS protocol. When using it, the user also needs to provide authorization for the mounting behavior, so the operation is cumbersome and the requirements for the protocol are high.
