KVM虚拟化技术中处理器隔离的实现

摘要

KVM是基于Intel VT技术并结合QEMU来提供设备虚拟化的虚拟机.通过分析和研究KVM虚拟机的创建、运行机制,从进程控制的角度对KVM虚拟机进行隔离,实现了KVM虚拟机在创建、运行时都保持在指定的核上运行,达到最大化利用处理器资源的目的.%KVM (Kernel-based Virtual Machine) is a virtual machine based on Intel VT technology and works with QEMU, which provides device virtualization. From the process point of view, this paper focuses on the analysis of the initiative and the running mechanism of KVM virtual machine, based on the analysis, a method of isolating KVM virtual machine is implemented, which makes the KVM virtual machine run on the specified core whenever it's created or running, and achieves the maximized utilization of processor resources.
