Quick modularized assembling method, device and system of virtual machine disk mirror image

Abstract

The invention provides a quick modularized assembling method, device and system of a virtual machine disk mirror image. The quick modularized assembling method of the virtual machine disk mirror image comprises the following steps: receiving a virtual machine disk mirror image request; according to the type of an operating system and assembly description information, obtaining assembly information corresponding to the virtual machine disk mirror image request in an assembly database; according to an assembly identifier, detecting whether an assembly corresponding to each assembly identifier has a conflict or not; and if the assembly corresponding to each assembly identifier does not have the conflict, obtaining the assembly from an assembly memory pool according to an assembly storage position, and assembling the assembly into a virtual machine disk mirror image file corresponding to the virtual machine disk mirror image request. The quick modularized assembling method of the virtual machine disk mirror image can assembly the virtual machine disk mirror image in an assembly form, saves the file storage space, and improves the assembling flexibility of the virtual machine disk mirror image.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device and system for quickly assembling a virtual machine disk image modularization. Background technique [0002] With the development of computer technology, computing resources have been greatly enriched and integrated. However, with the increase of available computing resources, the problem of underutilization of resources has become increasingly serious. Taking computing resources of a traditional data center as an example, the utilization rate of a central processing unit (Central Processing Unit, CPU for short) is less than 20%. Therefore, efficient integration and utilization of resources has become a very important issue. [0003] In order to improve resource utilization, virtualization technology is proposed in computer technology. Virtualization technology is a resource management technology that adds a virtualization layer between the physical hardware ...
