Problems solved by technology

[0003] Since the existing migration tool can only perform merge format conversion for each image file of the virtual machine disk, that is to say, after the image format conversion of the virtual machine disk, each disk corresponds to an image file, and each disk is finally a mirror image. When migrating to a new virtualization platform, the chain structure of the original virtual machine disk image file on the original virtualization platform cannot be maintained

Embodiment 1

[0091] Embodiment 1: Migration of virtual machines between the same storage system of the same manufacturer and different platforms

[0092] refer to Figure 6 , this embodiment elaborates the process steps of the cutover and migration of the virtual machine from the XEN platform to the KVM platform. This embodiment is the migration of the virtual machine between different platforms and the same storage system to maintain a chain relationship, including:

[0093] 1) Select a virtual machine: First, select a virtual machine that needs to be migrated under the original virtualization platform. The name of the virtual machine is testVM. Click the browse button provided on the interface to view the XML file, disk, etc. of the virtual machine Basic Information.

[0094] 2) Conversion configuration: Then the system automatically lists the disk node chain information of the virtual machine under the original virtualization platform. For example, the virtual machine shown in this exa...

Embodiment 2

[0097] Embodiment 2: Migration of virtual machines between different platforms and different storage systems of the same manufacturer

[0098] refer to Figure 7 , this embodiment elaborates the process steps of the cutover and migration of the virtual machine from the XEN platform to the KVM platform. This embodiment is the migration of the virtual machine between different platforms and different storages to maintain a chain relationship, including:

[0099] 1) Select a virtual machine: First, select a virtual machine that needs to be migrated under the original virtualization platform. information.

[0100] 2) Conversion configuration: Then the system automatically lists the disk node chain information of the virtual machine under the original platform. For example, the virtual machine shown in this example is a chained virtual machine. The original disk node chain contains 4 files in VHD format. The actual size of the file from the root node to the leaf node is 40G, 10G,...

Embodiment 3

[0103] Embodiment 3: Virtual Machine Switching between Different Vendors, Different Platforms and Different Storage Systems

[0104] refer to Figure 8 , this embodiment elaborates the process steps of virtual machine cutover and migration from XEN platform to KVM platform. Specify the target repository, specify which nodes participate in the merge and which nodes maintain chain flexible configuration, including:

[0105] 1) Select a virtual machine: First, select a virtual machine that needs to be migrated under the original virtualization platform. information.

[0106] 2) Conversion configuration: Then the system automatically lists the disk node chain information of the virtual machine under the original platform. For example, the virtual machine shown in this example is a chained virtual machine. The original disk node chain contains 4 files in VHD format. The actual size of the file from the root node to the leaf node is 40G, 10G, 5G, 2G. The list also shows the locat...

Abstract

The invention discloses a virtual machine migration method and device, and electronic equipment. The method includes: selecting a virtual machine to be migrated from the original virtualization platform; obtaining the original disk of the virtual machine in the original virtualization platform Node chain information; according to the original disk node chain information, configure the target disk node chain information; based on the target disk node chain information, convert each file in the original disk node chain of the virtual machine, so that the The virtual machine is migrated from the original virtualization platform to the target virtualization platform.

Description

technical field [0001] The present invention relates to virtual machine migration technology, in particular to a virtual machine migration method and device, and electronic equipment. Background technique [0002] Many enterprises, education, medical and other institutions have their own cloud desktops. In the initial stage of the resource pool cloud data center, based on a series of factors such as cost ease of maintenance and solution limitations, only a more mature virtualization solution may be selected. In the mid-to-late stage, driven by various requirements such as high performance and solution optimization, it is necessary to completely or selectively migrate some virtual machines in the original virtualization platform to the new virtualization platform. This involves the migration of virtual machines between different virtualization platforms. The current migration solution is to use the existing migration tools to export the image, perform forced image format con...
