Abstract

Abstract---Virtualization is a technical innovation designed to increase the level of system abstraction and enable IT users to harness ever-increasing levels of computer performance. The most fundamental part of virtualization is the hypervisor. To perform maintenance on a host server, we need to be able to move all of its VMs onto other host servers with minimum disruption to end users. Even more importantly, if our virtual workloads peak and need more resources, our virtual infrastructure should be able to automatically locate a host server with adequate resources and move the VMs to this host. And the entire process should be completely transparent to end users. VM migration, especially live migration is a desirable feature in Grid and Cloud Computing systems for load balancing, elastic scaling, fault tolerance, and hardware maintenance. The security and reliability issues that reside in VM live migration is a critical factor for its acceptance by IT industry. Though the performance is optimized through live migration, there are two important issues to be noted, reliability and security. In this paper, we propose how to migrate a VM Guest to another VM Host Server. We discuss the steps regarding the KVM live migration requirements and the security and reliability issues in live migration.

KVM虚拟机热迁移的安全性

摘要——虚拟化是一种技术创新，旨在提高系统抽象水平，使IT用户能够利用不断提高的计算机性能水平。虚拟化最基本的部分是管理程序。要在主机服务器上执行维护，我们需要能够将其所有虚拟机移动到其他主机服务器上，同时尽量减少对最终用户的干扰。更重要的是，如果我们的虚拟工作负载达到峰值并需要更多资源，我们的虚拟基础架构应该能够自动定位具有足够资源的主机服务器，并将虚拟机移动到该主机。整个过程应该对最终用户完全透明。虚拟机迁移，特别是实时迁移，是网格和云计算系统中用于负载平衡、弹性扩展、容错和硬件维护的理想特性。虚拟机动态迁移中存在的安全性和可靠性问题是IT行业是否接受它的关键因素。虽然通过实时迁移优化了性能，但有两个重要的问题需要注意:可靠性和安全性。在本文中，我们提出了如何将VM客户机迁移到另一个VM主机服务器。我们将讨论有关KVM实时迁移需求的步骤以及实时迁移中的安全性和可靠性问题。
