不久微软也公布了相关内容 ，其中关于默认值的部分值得关注:Recommended Defaults for Enabling/Disabling Virtualization Extensions. The default setting of this switch requires some thought. Consider the costs of disabling Intel Virtualization Technology/AMD Virtualization through a system firmware setting: If these facilities are disabled by default in system firmware， users would have to explicitly enable that support on each platform instance for legitimate uses， which would represent a significant challenge for enterprises that have thousands of machines and plan on using the hardware extensions. The cost of enabling virtualization hardware support through a manual system firmware setting would result in an increase in deployment time and cost. This cost can be mitigated through the use of various in-band and out-of-band mechanisms for remote management. Given the current usage model for the virtualization extensions， we believe that the following default settings are the right ones for system firmware: For systems that are destined for a server role ， enable the virtualization extensions. The threat of running malicious code as an administrator on servers is reduced through Windows Server policies and organizational best practices. For systems that are destined for a client role， disable the virtualization extensions. For systems that might be deployed in either a server or client role ， it would be prudent to disable the extensions by default. As always， the exception to any guideline is when a customer specifically indicates to a manufacturer that they do not want to follow that guideline.
cpu支持虚拟化技术。关键看主板是否支持了，进bios里面看下cpu configuration里是否有amd-v或secure virtual machine，改为enabled，再按 f10保存退出即可。虚拟化技术是集成指令来的，不需要打开的，直接用的。
某厂家基于 Renesas H3/M3 + QNX Hypervisor2.x 开发了支持 “一芯多屏” 的 KSC3.0 智能座舱虚拟化平台 ， 可实现在一颗 SOC 上同时运行 QNX 仪表、Android 中控及副驾等多个系统，并支持以下特性:4 个屏幕同时输出。
1974年，两位计算机科学家Gerald Popek 和 Robert Goldberg发表了一篇重要的论文《虚拟化第三代体系结构的正式要求》，在这篇论文中提出了虚拟化的三个基本条件:等价性:程序在本地计算机执行和在虚拟机中执行应该表现出一样的结果。
