随着个人计算机硬件的快速发展，通过虚拟化技术构建多个孤立的计算域已经成为个人计算机的未来发展方向。为了避免在传统IA-32体系结构上通过软件虚拟化技术实现VMM所带来的困难，设计并实现了一种基于Intel VT-x技术的VMM- Pcanel/V2。Pcanel/V2利用最新的硬件虚拟化技术，配置一个可控的虚拟执行环境，直接运行多个操作系统，无需修改源代码。在监控客户操作系统对硬件资源的访问的同时，客户操作系统中出现的各种敏感情况也可以通过Pcanel/V2进行相应的处理。在Pcanel/V2上实现了Linux和Linux Works的并行执行，相应的评测结果表明，与软件虚拟技术相比，Pcanel/V2体系结构简化了设计过程的复杂性，同时整体性能提高了约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 guest operating system are monitored,various sensitive situations which occur in the guest 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.
