Embodiment Construction

[0018] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0019] The present invention provides a method for migrating virtual machine clusters based on multicast, comprising the following steps:

[0020] When the virtual machine is migrating, the migration request of the virtual machine cluster enters the task pool;

[0021] The sender obtains the information of the mapping table and calls the migration API according to the tasks of the task pool to complete the migration of the virtual machine cluster.

[0022] Wherein, the mapping table stores the mapping relationship between the virtual machine and the destination host.

[0023] Wherein, the updating method of the mapping table is as follows: the scheduler determines the destination host machine for t...

Abstract

The invention provides a virtual machine cluster migration method and system based on multicast. The virtual machine cluster migration method and system based on multicast are applied to the field of scheduling systems. The method includes the following steps that when a virtual machine is migrated, a migration request of a virtual machine cluster enters a task pool; a sender obtains information on a mapping list, an API is called and migrated according to tasks of the task pool and migration of the virtual machine cluster is finished. A multicast migration mechanism and a virtual machine arrangement strategy based on comprehensive computing strength are adopted for achieving migration of the virtual machine cluster in cloud computing, consumption of network resources in the migration process is reduced and the migration efficiency is improved.

Description

technical field [0001] The invention relates to the field of scheduling systems, in particular to a multicast-based virtual machine cluster migration method and system. Background technique [0002] At present, cloud computing is gradually recognized by the industry, and cloud data center operating systems are gradually realized and put into practice. Virtual machine migration is the core of cloud computing scheduling. The current virtual machine migration technology is mainly single virtual machine migration, from single physical machine to single physical machine. [0003] In practical applications, it is more mainstream to apply virtual machines in the form of clusters, but the migration of virtual machine clusters is a serial process, the migration time is too long, and the network bandwidth is high. Contents of the invention [0004] The present invention provides a multicast-based virtual machine cluster migration method and system to solve the above problems. [0...
