Problems solved by technology

[0002] As an open source cloud computing management platform, OpenStack has practical applications in many practical projects. The virtual machine snapshots of the OpenStack platform are managed by the Glance service project used to implement mirroring services. The Glance service project creates and restores snapshots. Due to the Glance service The project cannot save the snapshot chain, and cannot create multiple snapshot branches. It is not perfect in the snapshot function of the cloud host, and cannot achieve a more complete management of the snapshot of the cloud host.
At the same time, it takes a long time to save the snapshot created for the virtual machine to the storage backend of the Glance service project; in addition, when the number of snapshots is large, it will take up a large amount of storage space in the storage backend of the Glance service project

Abstract

The invention discloses a method and a device for managing virtual machine snapshots of an OpenStack platform. The method comprises the steps that when a snapshot creating request for a system disk and a data disk of an OpenStack platform virtual machine is received, a snapshot of the system disk of the virtual machine is created in the storage rear end where the system disk of the virtual machineis located, and the snapshot of the data disk of the virtual machine is created in a cloud hard disk; and recording snapshot of the system disk of the virtual machine and attribute information of thesnapshot of the data disk in a database. The snapshot of the system disk is created in the storage rear end where the system disk of the virtual machine is located, and the snapshot of the data diskis created in the cloud hard disk, so that the data pressure of the Grance service project can be reduced, and less storage space of the storage rear end of the Grance service project is occupied. Dueto the fact that the attribute information of the snapshot is recorded in the database, the snapshot recovery virtual machine can be conveniently adopted according to the snapshot chain.

Description

technical field [0001] The present application relates to the field of cloud computing, and in particular, to a method and apparatus for managing snapshots of virtual machines of an OpenStack platform.
