In the embodiment of the invention, a user can submit an application for configuring the virtual machine at a client of the terminal for configuring the virtual machine. Specifically, an OA system for configuring the virtual machine is provided on the terminal, a user submits a requirement for configuring the virtual machine by logging in the OA system, and an administrator logs in the OA system and confirms a configuration work order submitted by the user.
