Embodiment Construction

[0036] The present invention provides a method for virtual machine image caching in a cloud computing system, which divides all computing nodes in the cloud computing system network into multiple clusters, and makes full use of the idle time of the computing nodes by sharing the virtual machine cache mirroring inside the cluster Disk resources save hardware costs and shorten virtual machine startup time. The present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] like figure 2 As shown, the method for virtual machine image caching in the cloud computing system provided by the present invention comprises the following steps:

[0038] A10. Divide all computing nodes in the cloud computing system network into multiple clusters. The division principle is that several computing nodes adjacent to the physical location of the network are grouped into one cluster. This embodiment only uses cluster 1 and cluster 2 as examples. Obvio...

Abstract

The invention discloses a caching method of a virtual machine mirror image in a cloud computing system, which comprises the following steps of: A10, dividing all computer nodes in a cloud computing system network into multiple clusters; A20, respectively arranging a sharing cache for storing corresponding virtual machine mirror image of each computer node in the cluster in each cluster; and A30, when a computation node in one cluster requires operating a virtual machine example, downloading the corresponding virtual machine mirror image to the sharing cache in the cluster, establishing a corresponding virtual machine mirror image copy in the sharing cache, and when the virtual machine example is closed, deleting the corresponding virtual machine mirror image copy from the sharing cache. According to the invention, the flow transmitted by the sharing virtual machine mirror image is limited in the cluster to the greatest extent, the mirror image copy is hung to the computation node in a shared file manner, and the example can be started without downloading the mirror image file, so that the virtual machine starting time is shortened and the expense is lowered.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a method for virtual machine image caching in a cloud computing system. Background technique [0002] Cloud Computing (Cloud Computing) is an Internet-based computing method. Data processing and storage are completed through server clusters in the cloud. Information is provided to computers and other devices on demand, so that each device can exert its maximum performance. [0003] The virtual machine-based cloud computing system is based on a unified management of physical resource pools, and uses virtualization technology to provide a virtual computing environment according to user needs. In cloud computing systems, system files and user data are usually separated. Among them, the virtual machine image refers to the disk file that encapsulates the entire operating system, and the virtual machine image copy is the image file used when the virtual machine is running, similar to the s...
