Virtual machine template mirror image storage method based on fusion architecture cloud platform

Abstract

The invention relates to the field of cloud computing virtual machine template storage, and discloses a virtual machine template mirror image storage method based on a fusion architecture cloud platform, which comprises the following steps: adding SSD hard disks at all node hard disks, and storing template mirror images into the SSD hard disks when the template mirror images are stored; and if theSSD hard disk is not added at the node hard disk of the cloud platform, storing a mirror image template copy at each node hard disk when the template mirror image is stored. According to the virtualmachine template storage method provided by the invention, the template data is scheduled and stored in the SSD hard disk, so that the template access speed is increased; meanwhile, the template is stored in each node, the data reading pressure of a single template is reduced, the virtual machine of the node can directly read the template mirror image data of the machine, cross-node reading is notneeded, the IO path is shortened, the reading efficiency is improved, and the startup storm of the virtual machine is effectively relieved.

Description

technical field [0001] The invention relates to the field of cloud computing virtual machine template storage, in particular to a virtual machine template image storage method based on a fusion architecture cloud platform. Background technique [0002] With the advent of the cloud computing era, the use of virtualization technology is inevitable. Virtualization technology enables the abstraction of originally fixed and difficult-to-scale physical resources into configurable virtual resources using software. This flexible approach also breaks the original physical boundaries, and the computing resources and storage resources required by virtual machines are distributed in different physical nodes. In a virtualization environment, there are two ways to clone a virtual machine, template linked clone and full clone. The linked clone virtual machine depends on the original template, and the new virtual machine image will only write new data, while the full clone Cloning will co...

AI Technical Summary

Problems solved by technology

The virtual machine is running and distributed on all hyper-converged nodes, but the template image will only be stored on the node with the number of copies (generally 3). When the virtual machines on other nodes start, they need to access the node with the template copy through the network, so the template storage Reading performance bottlenecks will restrict the performance of virtual machines on the cloud
