Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] Step 1: If image 3 Collect the historical resource utilization rate of the virtual machine, analyze the resource utilization rate of each virtual machine according to formula (1), and judge whether the virtual machine is in a state of high consumption. The present invention finds in experiments that the resource utilization rate is at The threshold of 0.8-0.9 is in a state of high consumption without reducing system performance. The present invention carries out the corresponding analysis experiment of the resource utilization rate and the virtual machine response time, and sets the resource utilization rate threshold value which does not affect the system response time. A virtual machine that is judged to be in a high-consumption state is removed from the virtual machine pairing queue.

[0038] The algorithm for resource saturation is as follows:

Abstract

The invention relates to a method for placing a load-related virtual machine. In a currently common virtualized environment, in order to ensure performance, resources are often excessively allocated, leading to a low resource utilization level and resulting in increase of the cost and resource waste. By utilizing a multi-iteration complementary pairing method provided by the invention, the problems of a low resource utilization ratio as well as unreasonable pairing caused by random pairing or one-time pairing can be solved; and the iteration degree is controlled by setting a saturation of the resource utilization ratio, so that the performance of the system and the service quality of a user are controlled within an acceptable range. By a multi-iteration virtual machine method, by utilizing the time complementarity of the resources, the resource utilization ratio of the virtual machine can be improved in a relatively deep level on the premise of not reducing the service quality of the user.

Description

technical field [0001] The invention belongs to the technical field of virtual machine capacity planning, and relates to a load-related virtual machine placement method. Background technique [0002] Virtualization is a technology widely used in server systems and data centers at present. It allows users to obtain resources such as computing and storage on demand, and is scalable and easy to manage. In the currently commonly used virtualization environment, in order to ensure performance, excessive resource allocation is often performed, resulting in a low utilization rate of resources, and resulting in increased costs and waste of resources. Before using the virtualization platform to provide user services, reasonable virtual machine placement on the built virtualization platform can save costs and provide good resource guarantee and resource scalability for the later operation of the virtualization platform. [0003] Traditional virtual machine placement methods mainl...
