摘要

针对基于Xen的vCPU调度机制对虚拟机网络性能的影响进行了深入研究和分析。提出一种高效、准确、轻量级的网络排队敏感类型虚拟机（NSVM）识别方法，可根据当前虚拟机I/O传输特征将容易受到影响的虚拟机进行准确识别和区分。进而设计一种新型虚拟计算资源调度和分配机制 Diff-Scheduler，将不同类型虚拟机的vCPU实施分池隔离调度，同时提高NSVM类型虚拟机vCPU的调度频率。原型系统实验结果表明，相比Xen默认的调度机制，Diff-Scheduler能够大幅提高虚拟机网络性能，同时保证计算资源分配的公平性。

Abstract

A deep insight into the relationship between vCPU scheduling and I/O transmit in Xen was provided.Then an effective and lightweight recognition method

through which could identify the so-called NSVM (network queuing sensi-tive virtual machine) that was more vulnerable to the congestion in I/O transmit was put forward.Furthermore

a novel mechanism for resource assignment and scheduling called Diff-Scheduler was proposed.It could schedule the vCPU of the NSVM more frequently than other VM in different pools independently.Evaluations based on a prototype of Xen platform featured Diff-Scheduler show that the proposed mechanism significantly improves the network performance of VM.Specifically

comparing with the default mechanism of Xen

Diff-Scheduler proposed jointly enhances throughput

latency remarkably and ensures the fairness of resource allocation at the same time.
