【摘要】在云计算蓬勃发展这个外因的驱动下，虚拟 化技术作为云计算的关键技术平台也正不可逆转地发展着。 虚拟化使得一台计算机上能够运行多个虚拟机，虚拟机之间 有很强的隔离性，且虚拟机与硬件没有直接的关联。论文从 虚拟化出现的原因入手，进而介绍UVP虚拟化平台的架构、 特点以及在虚拟化平台中使用的性能优化技术、节能管理技 术、安全实现技术以及UVP的增强技术等，使用这些关键技 术意义在于提高系统性能、增强安全性、易于后期维护和扩 展等。

【Abs tract 】 Because of the rapid grow th of cloud computing technology, virtualization, which is the key component of cloud computing, is experiencing fast development at irreversible rate. The technology of virtualization enables the operation of multipie virtual machines on one physical machine. While virtual machines can share the physical resources of a single computer, they remain completely isolated from each other as if they were separate physical machines. Virtual machines are completely independent from their underlying physical hardware. This paper initiates the research from the reason why virtualization came into being, and goes onto introduction of the structure and characteristics of the UVP virtualization platform,including thetechnologyof performance optimization, energy efficiency management, security implement and UVP' s enhancement. In addtion, it states the significance of those mentioned technology, such as improving system performance, strengthening security, easysystemmaintenance and expansion and so on.
