Virtual machine creating method and device for virtual machine creation

Abstract

The invention discloses a virtual machine creating method and a device for virtual machine creation. The virtual machine creating method includes invoking virtual machine creation steps and performing the invoked virtual machine creation steps, wherein after every time an invoked virtual machine creation step is successfully performed, the next virtual machine creation step which needs to be invoked is determined based on a predetermined sequence of the virtual machine creation steps. According to the virtual machine creating method and the device for the virtual machine creation, each virtual machine creation step is invoked separately, after the invoked virtual machine creation step is performed successfully, the next virtual machine creation step is invoked, and therefore a fault can be located accurately, the situation that all the steps need to be preformed again in the case of a creation failure is avoided, and efficiency of the virtual machine creation can be improved; and moreover, even when a virtual machine creating process needs to be adjusted, only a part of the steps needs to be amended, workloads can be effectively reduced, the complexity in the virtual machine creation process is lowered, and maintainability and scalability can be improved.

Description

technical field [0001] The present invention relates to the computer field, and in particular, relates to a method and device for creating a virtual machine. Background technique [0002] In cloud computing, the use and allocation of computing resources basically revolves around virtual machines. By integrating existing software and hardware resources, creating different configurations and types of virtual machines for rent to users, this application scenario has become a basic feature of cloud computing. The creation of a virtual machine is a complex and tedious process that requires interaction with multiple subsystems. For example: making an image file for a virtual machine, configuring the network card, bandwidth, CPU, memory, etc. of the virtual machine. Any problem in each link will directly affect the creation result of the virtual machine, and eventually cause the virtual machine to be unavailable. [0003] The whole process monitoring and exception handling of th...
