Method and system for scheduling virtual machine quick start and physical machine capacity expansion in shooting range

Abstract

The invention discloses a method and system for quick start-up scheduling of a virtual machine and capacity expansion of a physical machine in a shooting range. The invention numbers each physical machine in the cluster and the image file on which the virtual machine depends, sets the numbers of all the physical machines in the cluster within a numerical range, and calculates an addressing value according to the image number when requesting to start the virtual machine , determine the number of the physical machine based on the addressing value, and perform resource judgment to determine the physical machine for finally creating the virtual machine. The present invention can dispatch the same type of image to the same physical machine with a high probability to perform virtualization, thus avoiding the traffic storm caused by irregular random scheduling, and specifying the image to be virtualized multiple times on a physical machine does not need to download the image repeatedly files, which optimizes the user experience compared to random scheduling. The present invention can expand the capacity of the hotspot image, ensuring that the newly added physical machine only executes the virtualization of the current hotspot image with a high probability, and does not affect the normal use of other images.

Description

technical field [0001] The invention relates to a method and system for quick start-up of a virtual machine in a shooting range and expansion of a physical machine, and belongs to the fields of virtual network platforms and computer software. Background technique [0002] The network shooting range is a test platform that simulates the real cyberspace offensive and defensive combat environment through virtualization technology, and can support combat capability research and weapon equipment verification. The virtualization of the shooting range is mainly the instantiation process of the network nodes in the shooting range. Instantiating each network node means using a specific image to create an available virtual machine on a physical machine. [0003] From the perspective of virtualization, the architecture of the shooting range is as follows: figure 1 shown. Among them, the control system: receives the user's operation instructions, such as the shooting range instantiati...

Problems solved by technology

[0005] The existing solutions have the following problems: 1. The scheduling strategy for specifying image virtualization is not related to the image itself. For the image, the process of scheduling a physical machine to perform virtualization is random, and it needs to be downloaded from the image center before actual virtualization. The size of the image file is usually several G when the image file is uploaded locally. The random image download of each physical machine will easily cause the traffic in the network to become a bottleneck; 2. Because the scheduling policy is not related to the image, it is easier to schedule the start of the virtual machine The physical server that downloads the image, the physical server needs to download the image first to perform actual virtualization, the process of downloading the image takes a long time, and the user experience is not good; 3. For the frequently used hotspot image, it is impossible to add hardware devices to it, thus Targeted optimization
