Xen-based virtual machine deployment system and Xen-based virtual machine deployment method

The invention belongs to the field of quick virtual machine deployment systems, discloses an Xen-based virtual machine deployment system and an Xen-based virtual machine deployment method and solves the problem that an existing quick Xen virtual machine deployment system cannot meet large-scale cloud environment requirements and fails to dynamically change IP (internet protocol) addresses and software environments of virtual machines. According to demands of users, a JSP webpage server, a Tomcat webpage server and an MySQL database are combined to serve as a front end of a front-end system and a management system, a front-end server is in interaction with the users and sends different instructions to load servers by means of adoption of a Livbirt control library for communication according to configuration parameter information of user demands acquired from interaction, and the front-end system selects increment mirror images in a mirror image template library and carries out one-key deployment of different operating systems and one-key deployment of virtual machines for different applications by means of virtual machine increment for deployment; the IP addresses of the virtual machines are automatically configured according to the information of user demands. On the basis of the different deployed operating systems and the deployed virtual machines for different applications, life cycles of the virtual machines can be controlled by the users; in addition, the software environments of the virtual machines can be changed dynamically.
