Problems solved by technology

[0003] Taking the open source Openstack platform as an example, the virtual disk formats mainly include unformatted (RAW) and QCOW2 formats. Among them, when the virtual machine uses the RAW format as storage, the IO efficiency is the highest, but it also occupies the largest space. When downloading from the mirror node Template mirroring takes the most time

Abstract

The present invention discloses a method and apparatus for improving transmission efficiency of a virtual machine template. The method comprises: after generating a virtual machine template, generating a corresponding template description file for the virtual machine template, wherein a range of all non-zero byte blocks in the virtual machine template is recorded in the template description files; and before downloading the virtual machine template, acquiring the template description file corresponding to the to-be-downloaded virtual machine template, analyzing the range of all the non-zero byte blocks of the to-be-downloaded virtual machine template, downloading and obtaining each non-zero byte block, and forming the to-be-downloaded virtual machine template with the non-zero byte blocks obtained by downloading. According to the method and apparatus for improving the transmission efficiency of the virtual machine template provided by the present invention, transmission consumption during a process of downloading the virtual machine template can be reduced, and transmission time of the virtual machine template can be greatly reduced, so that the transmission efficiency is improved.

Description

technical field [0001] The invention relates to a virtual disk technology, in particular to a method and a device for improving the transmission efficiency of a virtual machine template. Background technique [0002] Virtualization platforms such as Vmware, XenCenter, OpenStack, etc. generally have the concepts of image nodes and computing nodes. The image nodes mainly store virtual machine templates and provide download services for computing nodes, such as HTTP services. [0003] Taking the open source Openstack platform as an example, the virtual disk formats mainly include unformatted (RAW) and QCOW2 formats. Among them, when the virtual machine uses the RAW format as storage, the IO efficiency is the highest, but it also occupies the largest space. When downloading from the mirror node Template mirroring is also the most time-consuming. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a method and devic...
