Embodiment

[0017] On Yunhai OS, first create a source virtual machine, install the operating system on it, and deploy application software in the system, take a snapshot of the source virtual machine, and perform homologous copying of the generated snapshot files. Related commands of the source virtual machine, set the snapshot file of the source virtual machine as the image of each target virtual machine. Thereafter, when the target virtual machine starts to read data, it obtains the point-in-time information of the source virtual machine snapshot, and then reads the data of the source virtual machine according to the information to start. For increments of virtual machine changes after startup (input or output of data), additional storage guarantees the personalization of the application. Use this method to quickly deploy the same virtual machine system in Yunhai OS, which not only simplifies the work content, but also saves disk space.

Abstract

The invention provides a method for deploying a virtual machine rapidly in a smart cloud OS (operating system). In the method, terminal Linux commands and a mode of homologous snapshots are used for deploying the virtual machine rapidly. The invention has the following technical scheme as follows: on the smart cloud OS, at first, a source virtual machine is created, an operating system is installed in the source virtual machine, application software is deployed in the system, then the source virtual machine is snapshot, multiple copies of a snapshot file are copied, corresponding UUID (universally unique identifier) numbers are separately given to the snapshot files through executing the corresponding commands in distributed storage, the snapshots of the source virtual machine are set as the mirror images of other virtual machines, and thus, the same rapid deployment of the virtual machines is finished through the method of homologous mirror images. By using the method, work content is simplified, work risks are avoided, and the disk space is greatly saved as the homologous files are used.

Description

technical field [0001] The invention relates to computer technology related to the application of the Linux operating system, in particular to a method for quickly deploying a virtual machine in Yunhai OS. Background technique [0002] In recent years, the rapid development of information technology and the advent of the era of cloud computing have prompted the migration of large-scale applications to cloud computing platforms. Yunhai OS, as a representative product of cloud computing, often encounters the following problems when deploying application environments: Multiple virtual machines require Deploying the same application, including installing the operating system and application software, is undoubtedly a very cumbersome task for the implementers. First, the workload is heavy. In addition, there are too many repetitive tasks, and repeated deployment During the process, it is very likely that due to the negligence of the operator, a certain parameter or a certain conf...
