Method and device for resetting virtual machine user login password

Abstract

A method and apparatus for resetting a user-login password for a virtual machine are provided. The method includes: receiving a request to reset the user- login password for the virtual machine, wherein the request to reset the user-login password contains user identity information; verifying the user identity information to determine whether the request to reset the user-login password is valid; acquiring right of modifying data in a disk of the virtual machine in accordance with a preset mode when the request to reset the user-login password is valid; replacing user-login password encryption data corresponding to the user identity information stored in the disk of the virtual machine with user-login password encryption data backed up when the virtual machine was created. The invention can reset the user-login password for the virtual machine with relatively short time period and less system resources of a host. Furthermore, other users have no right of requesting reset, and the security of the virtual machine is ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to the field of information security technology, in particular to a method and device for resetting a virtual machine user login password. Background technique [0002] Currently, a server (host) equipped with virtual machine installation software can create one or more virtual machines with login passwords. For the same virtual machine created by the server, the user can log in to the virtual machine by entering the password through the terminal device, and perform a series of interactive command operations with the virtual machine. Different types of users have access to the resource files on the virtual machine. different. For example, the root user of a virtual machine under the Linux or Unix operating system has the operations of adding, deleting, modifying, and checking any resource file on the virtual machine. However, once the user forgets the corresponding virtu...

Problems solved by technology

[0004] During the research and practice of the prior art, the inventor found that the prior art has at least the following problems: the above-mentioned first method consumes a large amount of system resources of the host machine, takes a long time, and has data loss phenomenon; the above-mentioned second method This method will allow any user to enter the specific mode of the virtual machine corresponding to the user by means of a terminal device to reset the virtual machine login password, and then the security of the virtual machine cannot be guaranteed, for example, for a virtual machine under the Linux operating system , non-root users can enter the single mode of the virtual machine with the help of a terminal device to reset the virtual machine login password corresponding to the root user and obtain the authority of the super administrator account
