System and method for quickly constructing virtual machine in large-scale scene of network target range

Abstract

The invention discloses a system for quickly constructing a virtual machine in a large-scale scene of a network target range. The system mainly comprises a network target range platform and a virtualmachine scheduling module which are deployed at a network target range control node, and a virtual machine management module and a quick construction module which are deployed at a network target range computing node. According to the method, when a user starts a network target range scene topology, virtual machines with the same dependence software are dispatched to the same computing node preferentially, and CDROM equipment is added to the virtual machines when the virtual machines are started; repeated software packages are filtered according to the rapid construction information of the virtual machine, dependent software packages are downloaded, and an iso file is generated; and a CDROM path mounted on the virtual machine is modified after the virtual machine is started, and virtual machines with the same information is quickly constructed on the same computing node to share one iso file. According to the method, agent-free construction of the virtual machine in a large-scale sceneof a network target range can be realized, various initialization files can be supported, and network congestion is avoided.

Description

technical field [0001] The invention relates to a system and method for quickly building a virtual machine in a large-scale scene of a network shooting range, and belongs to the field of network technology. Background technique [0002] Some virtual machine templates based on the basic operating system and some tools or other software will be prefabricated in the cloud platform environment of the network range. The network range platform will form a network topology scene based on these templates and software. When the scene topology is started, it needs to be generated according to the virtual machine template. Virtual machine, but the virtual machine needs to assume different roles in different locations of the network topology, and the installed software is also different. When starting the network shooting range scene, different software needs to be dynamically installed according to the network location of the virtual machine to realize different roles. [0003] Rapid b...

Problems solved by technology

[0004] For the rapid construction of virtual machines in large-scale scenarios of network shooting ranges, the existing solutions have the following shortcomings: 1. The cloudinit software needs to be installed in the virtual machine in advance; 2. The rapid construction script can only be downloaded after the completion of network initialization; 3. It can only transmit fast Build scripts, fast build dependent software packages need to be downloaded through quick build scripts; 4. The virtual machine network needs to be able to communicate with the shooting range platform, otherwise it is impossible to download the fast build dependent software; 5. When a large number of virtual machines start, they will connect to The data service obtains the quick build script, and when executing the quick build script, it will connect to the shooting range platform to download dependent software packages at the same time, which will cause network congestion and eventually cause the quick build to fail
