Problems solved by technology

Although the above method is an algorithm for scheduling the migration process of multiple associated virtual machines after successful remapping, so although this algorithm takes into account the correlation between virtual machines, it does not perform the scheduling for the virtual machines that need to be migrated. remapping algorithm

Embodiment Construction

[0025] This specific embodiment provides a method for migrating multiple associated virtual machines between multiple data centers, the process of which is as follows figure 1 As shown, including the online processing of step A migration request, and step B remapping the first virtual machine VM of the VDC migration request 1, step C remaps all virtual machines of the VDC migration request, and step D implements the VDC migration request, specifically as follows:

[0026] Step A. Online processing of migration requests;

[0027] Define ExpiredVDC as a set of leaving VDC requests; assume in the present invention that each VDC migration request arrives according to a Poisson process; define an arrival queue of this migration request as ArrivedVDC in the present invention, and in this ArrivedVDC, each VDC Migration requests are remapped and migrated in sequence, that is, when a migration request is processed, the VDC migration request is first remapped, then the migration path i...

Abstract

The present invention provides a method of migrating a plurality of associated virtual machines among a plurality of data centers, and belongs to the cloud computing technology field. The method can be suitable for a whole virtual data center (VDC) migration request, and the plurality of associated virtual machines are in the VDC migration request, can be one virtual machine, and also can be more than two associated virtual machines, so that the application range of the method is wider by being compared with a conventional migration algorithm. According to the present invention, after the successful remapping of the whole VDC migration request, a migration path is found for each virtual machine until the migration paths of all virtual machines are found, and then all virtual machines are migrated by using a uniform parallel migration strategy, so that the shutdown time and the migration time are shorter than migrating the virtual machines one by one and orderly.

Description

technical field [0001] The invention belongs to the technical field of cloud computing, and in particular relates to a method for migrating multiple associated virtual machines between multiple data centers. Background technique [0002] With the development of the Internet, the number of users and enterprises connected to the Internet is increasing. Therefore, it is very difficult to modify the structure of the Internet, and the security performance of the network is reduced and the expansion of core routing is seriously affected, which hinders the development of the Internet. The development of new Internet technologies has led to the "ossification" of the Internet. In order to solve this problem, related researchers proposed the concept of cloud computing. Cloud computing service providers use network virtualization technology to divide physical computing resources and network resources into virtual resources so that these resources can be shared, thereby dividing physic...
