Abstract

The invention provides a virtual machine creation method, comprising the following steps of: receiving a request for creating a virtual machine, extracting the target template information in the request; searching the corresponding template according to the target template information; creating a snapshot of the target template, and setting the snapshot as a virtual disk of the virtual machine, and generating the configuration information of the virtual machine. The invention also provides a virtual machine creation system for realizing the above method, and a virtual machine resetting method and a virtual machine resetting system. With the adoption of the virtual machine creation method, the virtual machine creation system, the virtual machine resetting method and the virtual machine resetting system provided by the invention, the time for creating and resetting the virtual machine can be shortened, and the influence on normal operation of the created virtual machine caused by repeated real-write operations in the creation process can be avoided.

Description

technical field

[0001] The present application relates to the technical field of computer data processing, in particular to a method and system for creating a virtual machine, and a method and system for reinstalling a virtual machine. Background technique

[0002] Virtualization technology refers to the combination of software and hardware to divide a physical server into several isolated virtual machines, each of which can run programs independently without affecting each other. Virtualization technology makes physical resources more fine-grained, so that physical server resources can be more fully utilized and cost saved. In addition, virtualization technology turns the operation of physical server hardware into software operation, making deployment, modification, disaster recovery, etc. more convenient. Compared with running multiple applications on a single machine, using a virtual machine, the environment seen by the application and the Consistent on the physical serv...
