Embodiment 1

[0036] like Figure 1 to Figure 2 As shown, a method for live migration of virtual machines between cloud platform multi-clusters in an embodiment of the present invention is introduced, and the method includes the following steps.

[0037] In step S101, the first cluster copies the storage and memory of its virtual machines to the second cluster.

[0038]Before the hot migration, deploy the global network service in the first cluster and the second cluster. The global network service is a set of software-defined network components, which can realize the two-layer network intercommunication of different virtual machines between multiple clusters. In this embodiment, The global network service can ensure that the external business continues without interruption when the virtual machine is migrated between multiple clusters.

[0039] like figure 2 As shown, the first cluster and the second cluster use CPUs with different architectures, and each cluster has independent storage...

Embodiment 2

[0045] like Figure 3 to Figure 6 As shown, a method for live migration of a virtual machine among multiple clusters of a cloud platform in an embodiment of the present invention is introduced, and the method includes the following steps.

[0046] In step S201, the first cluster encrypts and compresses the storage of the preset data amount, and copies the compressed storage to the second cluster for decryption and decompression, and the first cluster copies the preset data amount to the second cluster.

[0047] Continuously copy the storage and memory of the first cluster to the second cluster. Since the storage is usually relatively large, in the process of copying the storage of the first cluster to the second cluster, the storage of the first cluster is encrypted and compressed Then copy it to the second cluster, decrypt and decompress it in the disk corresponding to the second cluster; the memory of the first cluster can be directly copied to the second cluster, so that th...

Abstract

The invention discloses a method and application for live migration of virtual machines among multiple clusters of a cloud platform, and the method comprises the following steps: a first cluster copies the storage and memory of the virtual machines to a second cluster, and the first cluster and the second cluster are deployed with global network services; and the first cluster virtualizes the CPU of the virtual machine of the second cluster into the type the same as that of the CPU of the virtual machine of the first cluster, and thermal migration is completed. According to the method, global network services can be deployed in two clusters before live migration of the virtual machines, two-layer network intercommunication of different virtual machines among multiple clusters can be achieved, and then external services of the virtual machines are continuously uninterrupted during migration; storage and memory data of clusters under CPUs of different architectures are synchronized, and virtual machines under the CPUs of different architectures are simulated to be of the same type, so that CPU instruction sets of the virtual machines started under the CPUs of different architectures are the same, and then thermal migration of the CPUs and registers is achieved.

Description

technical field [0001] The present invention relates to the field of cloud platforms, in particular to a method and application for hot migration of virtual machines among multiple clusters of cloud platforms. Background technique [0002] With the rapid development of computers, there are more and more upgraded servers in the data center, and the CPU models of each server vary widely, and the operating instruction sets supported by each server are also different. Multiple servers with different types of CPUs form a heterogeneous CPU server cluster. . Virtual machines are widely used in heterogeneous CPU server clusters. During their application, live migration of virtual machines may occur. [0003] To realize the hot and cold migration of virtual machines between multiple clusters on the cloud platform, the basic point is to migrate the disk data and memory data of the virtual machine at the source end, and to be able to rebuild a virtual machine at the target end , when...
