摘要
个人计算机硬件性能的迅速增强使得通过虚拟化技术建立多个相互隔离的计算域成为未来个人计算机的一种重要发展趋势.为避免传统的IA-32架构在软件虚拟化领域所面临的VMM的设计和实现的困难,作者设计并实现了基于Intel VT-x技术的VMM架构——Pcanel/V2.该架构利用最新的硬件虚拟化技术,通过配置出一个可控制的虚拟运行环境,可以直接虚拟运行多个不修改源代码的客户操作系统.在允许客户操作系统正常运行的同时控制它们对各种硬件资源的访问,并能对客户操作系统运行过程中出现的各种情况进行相应的处理.Pcanel/V2实现了Linux和Vxworks的同时运行,相应的数据测试表明Pcanel/V2架构在简化了VMM设计复杂度的同时总体运行效率比软件虚拟化技术提高了约10%.
With the rapidly development of personal computer hardware, to construct multiple isolated computing domains through virtualization technology has already become a future direction of PC. To avoid the difficulties caused by implementing VMM on traditional IA-32 architecture through software virtualization technology, the authors designed and implemented a VMM based on Intel VT-x technology--Pcanel/V2. Pcanel/V2 utilizes the latest hardware virtualization technology to configure a controllable virtual execution environment and run multiple operating systems directly without any modification of source code. While the accesses to hardware resources by the vip operating system are monitored, various sensitive situations which occur in the vip operating system can also be handled correspondingly by Pcanel/V2. Concurrent execution of Linux and VxWorks on Pcanel/V2 has been realized and corresponding evaluation results show that Pcanel/V2 architecture simplifies the complexity of the design process while increasing the overall performance by approximately 10% compared to software virtual technology.
