Virtual machine mirror image template uploading method of shared memory of cloud platform

Abstract

The invention relates to the field of cloud computing, and particularly relates to a virtual machine mirror image template uploading method of a shared memory of a cloud platform. The method comprisesthe following steps: firstly, requiring a mirror image service component to provide a mirror image uploading API on the shared memory, wherein the API request parameter contains the metadata information of a mirror image source; then calling the mirror image uploading API to perform data persistence on the metadata information of the mirror image source; sending the id of a mirror image, the sizeof the mirror image and path parameters of the mirror image source to mirror image uploading service where a host of the mirror image source is located; and finally creating an original file of the mirror image by the mirror image uploading service according to the id and the size of the mirror image, then converting a magnetic disk file of the mirror image source onto the original file of the mirror image, and accomplishing the mirror image template uploading after the conversion is accomplished. By adoption of the virtual machine mirror image template uploading method, the network transmission time of mirror image uploading on the shared memory is shortened; and the virtual machine mirror image template uploading method can be used on virtual machine mirror images.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method for uploading a virtual machine image template shared by a cloud platform. Background technique [0002] With the development of storage systems, more and more distributed and centralized storage systems and devices have emerged. In the process of using the cloud platform, the local storage system has gradually evolved into a distributed storage system, NAS and other storage, which can improve the reliability and stability of the stored data on the cloud platform, and facilitate the dynamic migration of virtual machines. The traditional way of packaging a virtual machine into a mirror image on the cloud platform is to first convert the virtual machine into a disk file, and then call the mirror component service to transfer the disk file through the network from the mirror source through the mirror component network. In a shared storage system, this puts a certai...

The traditional way of packaging a virtual machine into a mirror image on the cloud platform is to first convert the virtual machine into a disk file, and then call the mirror component service to transfer the disk file through the network from the mirror source through the mirror component network. In the system of shared storage, this puts a certain pressure on the network transmission of the image component, and also increases the time for image upload
