Detailed Description
The invention is further described below with reference to the figures and examples.
Fig. 1 is a flowchart of a method for implementing virtual machine template breakpoint resume issue through an agent according to the present invention.
Referring to fig. 1, a method for implementing virtual machine template breakpoint resume issue by using an agent according to an embodiment of the present invention includes the following steps:
s1: formulating a rule of cutting the template file of the virtual machine into file blocks, a rule of uploading the file blocks to the proxy server and a rule of downloading the file blocks from the proxy server by the receiving host;
s2: receiving an instruction of a host computer for initiating downloading of a virtual machine template;
s3: the file server cuts the virtual machine template file into file blocks according to the virtual machine template file cutting rule;
s4: the file server uploads the cut file blocks to each proxy server, and each proxy server prestores the uploaded file blocks;
s5: receiving file blocks downloaded by a host computer on each proxy server, saving a downloading state during interruption when downloading interruption occurs in the downloading process, and continuing downloading the downloading state during interruption after downloading is resumed;
s6: and the receiving host machine completes the downloading of all the file blocks, and the file blocks are automatically combined into a complete virtual machine template file in the receiving host machine.
Referring to fig. 2, in the method for implementing breakpoint resume of a virtual machine template by proxy according to the embodiment of the present invention, a file server stores an original virtual machine template file, the proxy server receives a file cut block of the virtual machine template file uploaded by the file server, a receiving host is a physical machine that needs to receive the virtual machine template file and deploy a virtual machine, and the receiving host completes downloading of the file cut block by the proxy server and then combines the file cut block into a complete virtual machine template file.
Specifically, in the method for implementing breakpoint resume and issue of the virtual machine template by proxy according to the embodiment of the present invention, when the virtual machine template file is cut into file chunks, uniform cutting is performed according to the size of the file; the file blocks are relatively uniformly uploaded to all the proxy servers, the receiving hosts download the file blocks from all the proxy servers in turn, and when the number of the receiving hosts is multiple, all the receiving hosts download the file blocks from all the proxy servers in turn. The file server cuts the virtual machine template file into a plurality of file blocks at intervals of a fixed size, and each file block is provided with a unique identifier and a block number of the file; and after the receiving host finishes downloading all the file blocks, the receiving host automatically combines the unique identification and the block number identification of the file carried by the file blocks into a complete virtual machine template file. The file server uploads different file blocks to each proxy server in turn, and performs balanced distribution according to the residual storage space of the proxy servers, and each proxy server distributes 60% of partial memory space to store the uploaded file blocks.
Specifically, in the method for implementing virtual machine template breakpoint resume issuing by proxy according to the embodiment of the present invention, a receiving host and each proxy server perform network verification, predict a download rate, alternately download file chunks on each proxy server according to a principle that a proxy server with a high download rate preferentially downloads, different receiving hosts at the same time download different file chunks on different proxy servers, and the receiving host preferentially downloads file chunks stored in a memory of the proxy server; when the downloading is interrupted in the downloading process, the downloading state during the interruption is stored in the database of the proxy server, the downloading state comprises file block information during the interruption and the position mark which is transmitted and completed, and the downloading information before the interruption is loaded and continuously downloaded after the downloading is resumed.
The method for realizing the virtual machine template breakpoint renewal issue through the proxy also comprises the steps that each receiving host acquires the virtual machine template information before the downloaded file is cut into blocks, and each receiving host synchronously carries out the personalized setting of the virtual machine while downloading the file blocks. When the network is interrupted during the personalized setting of the virtual machine, the personalized setting of the virtual machine is carried out again when the network is recovered.
Referring to fig. 3, a VMware vCenter Server manages a plurality of vspheres, each vSphere is based on a physical machine, and needs to run a plurality of virtual machines on the vSphere, and there are two ways for deploying a new virtual machine in the conventional method, that is: directly uploading a system ISO mirror image, and directly installing by creating an empty virtual machine mounting mirror image; the other mode is that a virtual machine template file prepared in advance through a vCenter is directly deployed into a virtual machine through personalized setting; the former is long in manual operation and time consumption, the latter is simple and convenient to operate and standard in deployment result, but vSphere under vCenter is distributed in a plurality of servers, template transmission time is long, and therefore downloading of virtual machine template files is achieved by a method of achieving breakpoint resume issuing of virtual machine templates through agents, and deployment of virtual machines is conducted simultaneously.
The vCenter is used as a file server, a virtual machine template file is prepared in the vCenter in advance, a plurality of Virtual Machines (VM) are created under the vCenter to serve as proxy servers, and vSphere serves as a receiving host. The vCenter splits a virtual machine template file into file blocks and uploads the file blocks to a proxy server, partial file blocks of a virtual machine template are pre-stored in a memory according to 60% of the memory size of the proxy server, when a plurality of vSpheres initiate an instruction for deploying the virtual machine through the template, the vSpheres alternately download the virtual machine template file blocks and preferentially download the file blocks in the memory, and preferentially acquire virtual machine template information before downloading the template, so that personalized setting of the virtual machine is synchronously performed while the template is downloaded. If network interruption occurs in the process of deploying the virtual machine through the template, the personalized setting of the virtual machine is carried out again when the network is recovered, and the transmission state before the network fault is carried by the rear-end template transmission to continue downloading until the deployment of the virtual machine is completed.
In summary, in the method for implementing breakpoint resume and issue of a virtual machine template by proxy according to the embodiment of the present invention, a proxy server is provided, so as to upload a virtual machine template file in blocks, and a plurality of receiving hosts are simultaneously connected to the proxy server to implement simultaneous downloading of file blocks, thereby avoiding the transmission bandwidth occupied by downloading a large file and increasing the downloading speed; meanwhile, the interruption of downloading is kept, and the downloading can be continued after the downloading is resumed, so that the downloading efficiency is improved.
Although the present invention has been described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
