Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing, please refer to figure 1 ; figure 1The system structure of the competitive resource differentiated service method proposed by the present invention is given. Among them, 1, 2, and 3 are the processors, memory, and disk resources available for allocation in the computing system, and 4 (in the dotted line box) is the virtual machine monitor. In addition to basic virtual machine management, the virtual machine monitor includes 5 , 6, 7, 8, and 9 are five parts, 5, 6, 7, 8, and 9 are the processor coordinator, the memory coordinator, the disk coordinator, the local resource coordinator, and the global resource coordinator are all residing in the virtual software program in the machine monitor. Among them, 5, 6, and 7 are the processor coordinator, memory coordinator, and disk coordinator for the above resource allocation respectively, 8 is the local resource coordinator, respon...

Abstract

The invention relates to a differential serving method for virtual system competition resources. Resource application features of a specific virtual machine application program are not differentiated in the conventional virtual machine monitor software and operating system, so that service quality of an important application program and a client operating system cannot be guaranteed. The method comprises three parts of contents: a Markov model used by the virtual system resources, a response time based service quality evaluation model of a multi-virtual machine system and a competition resource differential serving method based on the two models. Through the differential serving method for the virtual system competition resources, provided by the invention, competition degree of the system resources can be effectively relieved under the condition of high competition of the system, so that performance and service quality of the entire virtual system are obviously improved.

Description

technical field [0001] The invention relates to a method for realizing resource management and allocation of a virtualized computer system, in particular to a method for differentiated service of competitive resources among multiple virtual machines in a large-scale deployment of virtualized computing systems such as data centers and cloud computing environments. Background technique [0002] Although with the advancement of processor, memory and disk technology, the performance of a single computer continues to improve. However, the resource usage of a single computer is still low. The computing system virtualization technology can dynamically organize various computing resources, isolate the close dependencies between the specific hardware architecture and software systems, realize a transparent and scalable computing system architecture, and improve computing resources (such as processors, memory, etc.) ) has been widely used in both desktop and server fields, such as da...
