Network performance optimization method for KVM

Abstract

The invention provides a network performance optimization method for KVM. According to a KVM virtual machine system, the physical network card is simulated multiple virtual network cards. According to a virtual machine manager, each virtual network card is allocated to the virtual machine. The method comprises the following steps that S1. KVM virtual machine system detects the number of the virtual machine through a first CPU; S2. when the detected number of the virtual machine M1 is less than threshold value M, go back to the S1; S3. when the detected number of the virtual machine M1 is greater than or equal to the threshold value M, the first CPU determines the needed number of the virtual machine is N1; S4. according to the first CPU, the physical network card is allocated as N1 virtual network cards and S5. according to the virtual machine manager, the intel TV-d technology is utilized to add assigned virtual card for each virtual machine through a software. The network performance optimization method for KVM has the advantages of being capable of effectively improving the network performance of the system of multiple virtual machines during running in parallel under KVM.

Description

technical field [0001] The invention belongs to the field of KVM virtualization, and in particular relates to a KVM network performance optimization method. Background technique [0002] KVM is currently a more commonly used virtualization implementation solution. When the number of virtual machines running at the same time reaches a high number, the network bottleneck of KVM often becomes the key to restricting its performance. In order to improve network performance, simply replace the Gigabit network card. For 10 Gigabit network cards often can not get the desired results. [0003] With the use of 10 Gigabit NIC as the network communication method of KVM, how to better improve the network performance of the system and reduce the resource occupation of the system is an urgent problem to be solved. Contents of the invention [0004] In order to overcome the above problems, the present invention provides the following technical solutions: [0005] A network performance o...
