摘　　要：基于嵌入式系统对虚拟化环境的特殊要求,探讨如何设计虚拟机(VM)。针对工业实时控制,介绍了与第三方产品结合,把Intel虚拟化技术的好处拓展到应用中去。用虚拟化整合系统可以保证一定的实时性能;无需硬件冗余;进行软件移植而不简化应用。通过软件环境并行,虚拟化也允许原有的应用与新应用并存。它为多线程的应用在多核处理器上运行提供了途径。How to design Virtual Machine（VM）is explored in this paper,based on the special requirement of virtual environment for embedded system. For industrial real-time control, combining with third party product and extending the profit of Intel virtual technology to application is introduced. Real time performance is ensured by virtual consolidation system,without hardware redundancy and simplification of application with software migration. Virtualization also allows legacy application to co-exist with new application by software environment in parallel and it provides a way for multi-thread applications on multi-core processors,
