记者 | 彭新编辑 | 在2023年的世界移动通信大会（MWC）上，使用通用硬件和软件构建基站的虚拟化技术备受关注，成为英特尔进军通信市场的抓手。在MWC期间，英特尔发布了集成vRAN加速的新款至强处理器。
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.
近日有消息称，英特尔旗下公司Wind River（风河服务器）将开放网络功能虚拟化（NFV），为电信运营商提供更多的业务机会。英特尔Wind River将开放网络功能虚拟化（图片来自Yahoo）一直以来，NFV被认为可以简化客户提供服务所需的步骤。
虚拟化可以把一台电脑虚拟成多台虚拟机，可以充分利用电脑的性能。那电脑上需要做什么设置呢？主要是开启CPU的虚拟化指令支持功能。下面以thinkpad电脑为例，介绍一下设置方法：1、intel 平台①、电脑开机的同时，按F1进入BIOS，系统自动进入Main主页面。
Inetl VT-d介绍。Intel VT-d的全称是Intel Virtualization Technology for Direct I/O，它是Intel虚拟化技术的一部分，主要针对的是I/O子系统，它的实现主要是通过在硬件上引入重定向单元，该硬件重定向单元用于对I/O子系统的DMA操作和中断传递进行重定向，从而辅助VMM实现I/O子系统的虚拟化。
