Virtual machine mirror image generating method and device based on software preinstallation in cloud environment

Abstract

The invention discloses a virtual machine mirror image generating method and a device based on software preinstallation in cloud environment. The virtual machine mirror image generating method and the device based on the software preinstallation in the cloud environment comprise that softwares which are uploaded by users are received and dependency of the uploaded softwares are checked, operating system configuration information which is submitted by the users is received and analyzed to obtain analysis results of the operating system configuration information. Basic environment which is necessary to install an operating system based on the software preinstallation technology is generated according to the analysis results of the operating system configuration information. A virtual machine start is started by using a virtual machine start configuration file in the generated environment and a monitoring progress is started at the same time. An operating system installation program is operated in the virtual machine and the operating system is installed in a non-interactive mode. Meanwhile, the monitoring progress judges whether the installation of the operating system is wrong or accomplished or not. When the installation of the operating system is wrong, the virtual machine is closed and temporary files in the basic environment are cleaned and internet protocol (IP) address is returned to an IP address pool. The virtual machine mirror image generating method and the device based on the software preinstallation in the cloud environment can solve defects of an existing manner, wherein the defects of the existing manner are insufficient in flexibility, low in speed, serious in source consumption and the like.

Description

technical field [0001] The invention belongs to the field of cloud computing, and more specifically relates to a method and system for generating a virtual machine image based on software pre-installation in a cloud environment. Background technique [0002] With the development of cloud computing, cloud computing applications are becoming more and more diverse, and these applications all depend on the encapsulation of software by virtual machine disk images. Due to the vastly different needs of users, in order to meet the needs of users, the customized service of virtual machine image has become an indispensable part of each cloud computing platform. [0003] The existing virtual machine image customization can basically be divided into two categories: [0004] Modify the existing template: This method is to select an original virtual machine image on the cloud platform to start a virtual machine. After the user logs in to the virtual machine, he installs software on the v...
