Embodiment 1

[0041] Such as figure 1 As shown, the present invention provides a method for online migration of multi-disk virtual machines to different storage pools, including:

[0042] S1. Construct a disk tree for each active state disk to be migrated of the virtual machine and a plurality of snapshot disks corresponding to each active state disk to be migrated, and each disk tree includes at least the active state disk to be migrated Multiple snapshot disks generated by state disks are used to record the generation time sequence of multiple disks in the disk tree;

[0043] S2, migrate the memory snapshot file, and migrate the memory snapshot file of the virtual machine boot disk to the target storage pool of the boot disk; wherein, the boot disk is the disk where the virtual machine operating system is located;

[0044] S3. Determine the target storage pool corresponding to each active disk to be migrated, and migrate multiple disk trees to the corresponding target storage pool accord...

Embodiment 2

[0083] Such as Figure 5 As shown, the technical solution of the present invention also provides a device for online migration of a multi-disk virtual machine to a different storage pool, including:

[0084] The disk tree construction module 101 constructs a disk tree with each active state disk to be migrated of the virtual machine and a plurality of snapshot disks corresponding to each active state disk to be migrated, and each disk tree includes at least the Multiple snapshot disks generated by active disks to be migrated are used to record the generation time sequence of multiple disks in the disk tree;

[0085] The memory snapshot file migration module 102 migrates the memory snapshot file, and migrates the memory snapshot file of the virtual machine boot disk to the target storage pool of the boot disk; wherein, the boot disk is the disk where the virtual machine operating system is located;

[0086] The disk tree migration module 103 determines the target storage pool ...

Abstract

The invention provides a method for migrating a multi-disk virtual machine to different storage pools on line, which comprises the following steps of constructing a disk tree by using each to-be-migrated active state disk of the virtual machine and a plurality of snapshot disks correspondingly generated by each to-be-migrated active state disk, and recording the generation time sequence relationship of a plurality of disks in the disk tree; migrating the memory snapshot file; determining a target storage pool corresponding to each to-be-migrated active state disk, according to the generation time sequence relationship of the to-be-migrated disks in the disk tree, migrating the plurality of disk trees to corresponding target storage pools respectively. The invention further provides a device for migrating the multi-disk virtual machine to different storage pools on line. According to the method, the problems of low virtual machine migration resource utilization rate and low migration efficiency caused by the prior art are effectively solved, the to-be-migrated disk can be migrated to different target storage pools according to actual conditions during virtual machine disk migration,and the virtual machine migration efficiency and reliability are effectively improved.

Description

technical field [0001] The invention relates to the field of virtual machine disk migration, in particular to a method and device for online migration of a multi-disk virtual machine to different storage pools. Background technique [0002] With the rapid development of cloud computing technology, more and more companies have introduced virtualization management systems for providing basic functions of cloud computing. These virtualization management systems are deployed on servers so that all virtual machines can Share the server's resources. [0003] When the load of the host where the virtual machine is currently located is too large, the resources are insufficient, or the current environment needs to be developed and maintained, it is usually necessary to migrate the virtual machine to another host or storage to reduce the pressure, or wait for the current environment maintenance to be completed before the virtual machine migrate back. [0004] Moreover, virtual machin...
