Kernel virtual machine scheduling policy-based implementation method

Abstract

The invention discloses a kernel virtual machine scheduling policy-based implementation method. The method comprises two major steps of: 1, dividing Linux processes into a common process, a virtual machine process and a real-time process, making the priority of the virtual machine process between those of the common process and the real-time process, and providing a special scheduling algorithm for the virtual machine process; and 2, dividing virtual machines into a compute-intensive virtual machine and an I / O-intensive virtual machine according to demands of services in the virtual machines, and dynamically adjusting resources of each virtual machine to make the virtual machines better adaptive to the demands of the services in a client operating system. Due to the method, a kernel virtual machine has the priority to be scheduled during the scheduling process, each virtual machine can be fairly treated among a plurality of virtual machines, the resources of the virtual machines can be dynamically adjusted according to the service demands in the virtual machines, and the scheduling requirement of the kernel virtual machine is perfectly met. The method has a practical value and a wide application prospect in the technical field of computer virtual machine schedulers.

Description

(1) Technical field [0001] The present invention mainly relates to an implementation method based on a Kernel-based Virtual Machine (KVM) scheduling strategy, which realizes the coordination of resource competition between the Kernel-based Virtual Machine and the system process in the Linux environment, so that the Kernel-based Virtual Machine can To achieve better performance; in a multi-virtual machine environment, the virtual machines can use system resources more efficiently, and each virtual machine can achieve self-adaptive adjustment. In addition, the scheduling policy based on the kernel virtual machine reduces the switching overhead of the kernel virtual machine by reducing the number of virtual machine switching. The invention belongs to the technical field of a computer virtual machine scheduler. (2) Background technology [0002] 1. Virtualization technology [0003] Virtualization technology appeared in the 1960s and 1970s and was mainly applied to mainframes....

[0008] 3. Defects of the existing scheduling strategy of the kernel virtual machine

In this case, not only the higher-priority business in the KVM virtual machine cannot run, but also leads to the switching of the KVM process. This switch that should not have also increased the number of KVM process switching, thereby increasing the virtual machine switching overhead
