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

Embodiment Construction

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] The embodiment of the present invention provides a virtual machine template image storage method based on a cloud platform of fusion architecture, such as figure 1 shown, including:

[0032] S1: Add an SSD hard disk to the node hard disk of the cloud platform, and store the template image in the SSD hard disk when storing the template image;

[0033] S2: If no SSD is added to the node hard disk of the cloud platform, when the template image is stored, an image template is stored on each node hard disk.

[0034] Specifically, see figure 2 , in the step S1, the template image storage step after adding the SSD hard disk includes:

[0035] Create a template image, and calculate the hash value of the template image;

[0036] Determine the location where the template image is stored by comparing the hash value of the template image with the hash value range of the ...

Abstract

The invention relates to the field of cloud computing virtual machine template storage, and discloses a virtual machine template image storage method based on an integrated architecture cloud platform, comprising: adding SSD hard disks to hard disks of all nodes, and storing the template images when storing the template images If no SSD is added to the node hard disk of the cloud platform, when the template image is stored, a copy of the image template is stored on each node hard disk. The method for storing a virtual machine template provided by the present invention enhances the template access speed by scheduling and storing template data to an SSD hard disk; at the same time, storing the template in each node reduces the data reading pressure of a single template, and the virtual The machine can directly read the template image data of the local machine, without the need to read across nodes, shorten the IO path, improve the reading performance, and effectively alleviate the virtual machine boot storm.

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 cloud platform of fusion architecture. Background technique [0002] With the advent of the cloud computing era, the use of virtualization technology is inevitable. Virtualization technology makes the original fixed and difficult to scale physical resources abstracted into configurable virtual resources by software. This flexible method also breaks the original physical boundaries, and the computing resources and storage resources required by virtual machines are distributed in different areas. physical node. In a virtualized environment, there are two ways to clone a virtual machine: the linked clone of the template and the complete clone. The virtual machine of the linked clone depends on the original template, and the new virtual machine image will only write new data, while the complete...
