Problems solved by technology

Existing solutions cannot be considered for overall planning from a global perspective, which may result in remaining resources on multiple physical servers (for example, resources released after virtual machines are shut down and no new virtual machines need to be allocated for the time being), and some virtual machines on physical servers are shut down. Energy wasted in cloud computing data centers

Embodiment 1

[0055] Embodiment 1. A virtual machine mapping method of cloud computing data center, such as figure 1 Shown, including:

[0056] S101. Periodically count the number of virtual machines on each physical server in the cloud computing data center; when the number of low-load physical servers exceeds a first predetermined threshold, use the virtual machines in the low-load physical servers as virtual machines to be migrated, Go to step S102; the low-load physical server is a physical server whose number of mapped virtual machines is less than a second predetermined threshold N;

[0057] S102. Obtain resource utilization information of the low-load physical server.

[0058] S103. For the virtual machine to be migrated and the low-load physical server, generate multiple virtual machine placement strategies according to the resource utilization information, solve the energy consumption value of the generated virtual machine placement strategy, and determine the lowest energy consumption v...

Abstract

The invention provides a virtual machine mapping method and device for a cloud computing data center. The method includes that S101 the number of virtual machines on physical servers of the cloud computing data center is counted periodically; when the number of low load physical servers exceed the first preset threshold, the virtual machines in the low load physical servers are used as the virtual machines to be moved, then the step S102 is executed, and the low load physical servers are the physical servers with the number of the mapped virtual machines smaller than a second preset threshold; S102 the resource utilization rate information of the low load physical servers is utilized; S103 various virtual machine placing strategies are generated according to the resource utilization rate information aiming at the virtual machine to be moved and the low load physical server; S104 the virtual machines to be moved are mapped to the low load physical servers according to the determined virtual machine placing strategy. The method and device can reduce energy consumption of the cloud computing data center.

Description

Technical field [0001] The invention relates to the field of cloud computing, and in particular to a virtual machine mapping method and device of a cloud computing data center. Background technique [0002] Minimizing data center energy costs and improving data center performance are the main problems that cloud computing data centers need to solve. With the development of cloud computing and the growth of data center scale, how to reduce data center energy consumption and optimize data center performance is a current research focus. [0003] At present, when virtual machine mapping is performed on the cloud computing platform, when a new virtual machine is created, it searches for a physical server whose current remaining resources can meet the needs of the newly created virtual machine, and then maps the newly created virtual machine to the physical server found; if the current If the resources on the physical server used to map the virtual machine do not meet the demand, a new ...
