万物互联时代的虚拟化技术架构

1、万物互联时代的虚拟化技术架构技术创新 变革未来虚拟化技术的历史发展History of Virtualization Technology2003年， VMware ESX 后市场开始起步了这个时候英特尔硬件虚拟化技术还没有发布比二进制转换简单，性能比二进制转换好IBM, Intel, Amd, Redhat, SuSe, Oracle, HP也在Linux社区引起巨大反响开源虚拟化 XenXen Open Source Hypervisor一开始就定位优先合并进入Linux对Linux改动小2006年底出现，代码迅速被合并进入Linux，2008年公司被红帽收购快速开发就摈弃了Paravir
