Abstract

Live migration of virtual machines (VMs) enables the transfer of a running VM to a new hardware component with minimal and hardly noticeable interruption. It is an important feature of virtualization technology for maintenance, load-balancing and energy reduction, especially for data centers operators and cluster service providers. Recently, virtualization started to find its way into enterprise environments such as large and medium-sized IT companies. However, no feasibility study to highlight the pros and cons of such a trend has been conducted yet. In particular, a seamless live migration requires a reliable network connection and will have an impact on the network infrastructure. Therefore, this paper describes the design and set-up of our test bed to simulate a realistic implementation of virtualization in an enterprise environment. We tested three different scenarios of live migration and checked the impact of each scenario on the network infrastructure. Based on the implementation results, the paper introduces a list of recommendations for IT companies which might be interested in implementing virtualization and live migration.

调查企业环境中实时迁移对网络基础设施的影响
虚拟机的实时迁移支持将正在运行的虚拟机迁移到新的硬件组件,并且几乎不会出现明显的中断。对于数据中心运营商和集群服务提供商来说,这是虚拟化技术在维护、负载均衡和节能方面的重要特性。最近,虚拟化开始进入大型和中型IT公司等企业环境。然而,目前还没有可行性研究来突出这一趋势的利弊。特别是,无缝的实时迁移需要可靠的网络连接,并且会对网络基础设施产生影响。因此,本文描述了我们的测试平台的设计和设置,以模拟企业环境中虚拟化的实际实现。我们测试了三种不同的实时迁移场景,并检查了每种场景对网络基础设施的影响。根据实现结果,本文为可能对实现虚拟化和实时迁移感兴趣的IT公司提供了一系列建议。
