Method and device for virtualizing cloud platform to deploy virtual machine, electronic equipment and medium

Abstract

The invention discloses a method and device for virtualizing a virtual machine on a virtualized cloud platform, electronic equipment and a readable storage medium. The method comprises the following steps: mapping storage spaces from different storage devices for computing nodes of the virtualized cloud platform in advance; determining the disk space capacity of the virtual machine according to the configuration file of the virtual machine, wherein the virtual machine is mounted on the target computing node; generating a mirror image logic disk for the virtual machine based on the disk space capacity and each storage space of the target computing node; and storing the same data in each disk space of the mirror image logic disk. The disk space position of the configuration file is modified to be the mirror image logic disk, and the mirror image logic disk provides disk space for the virtual machine, so that data of the virtual machine can be directly written into multiple disk spaces of the mirror image logic disk at the same time, the probability of interruption of virtual machine service operated by the virtualization platform can be reduced, the possibility of data loss of the virtual machine is reduced, and it is ensured that virtual machine services can be stably and reliably operated on the virtualized cloud platform.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, electronic device and readable storage medium for deploying a virtual machine on a virtualized cloud platform. Background technique [0002] In the era of cloud computing, more and more businesses will be deployed on the cloud. Specifically, most businesses will choose to run their servers on the cloud in the form of virtual machines, which brings great challenges to business deployment and operation and maintenance. convenient. [0003] It is understandable that the disks of the virtual machines running on the virtualization cloud platform will inevitably fail. Since the virtual machine business deployed on the virtualization platform by related technologies has a single copy of the virtual disks used by the virtual machines, in After the disk fails, the virtual machine cannot run normally, not only will not lose data, but also affect the normal op...

Problems solved by technology

[0003] It is understandable that the disks of the virtual machines running on the virtualization cloud platform will inevitably fail. Since the virtual machine business deployed on the virtualization platform by related technologies has a single copy of the virtual disks used by the virtual machines, in After the disk fails, the virtual machine cannot run normally, not only will not lose data, but also affect the normal operation of the business on the virtual machine

Moreover, even with dual copies, it is impossible to switch the business to another copy without shutting down the virtual machine when there is a problem with one copy, which will bring business interruption to the business deployment of the virtualization platform. risk
