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.
2月8日下午,联想集团发布“联想问天”,这是该集团为中国本土市场打造的专属服务器品牌及产品线。对联想集团来说,在PC出货量持续下探的背景下,公司必须寻找新的增长点,以服务器和存储产品为主的ISG就是方向之一。
界面新闻记者 | 彭新 崔鹏界面新闻编辑 | 英特尔正通过其网络和边缘计算业务,努力实现网络基础设施开放和虚拟化转型。在2023MWC期间,英特尔宣布推出软、硬件解决方案,用于目前的RAN(无线接入网)架构中,应对市场变革。
本文章会详细介绍虚拟机系统的使用与常见问题,有很多读者都会遇到这样的情况,软件装不上,自己的电脑中软件很多,又不想换电脑系统,那么虚拟机可以帮你解决这个烦恼,由于文章内容写的比较详细,内容会比较多,可以收藏加关注,以免用到时找不到。
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。
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。
