1. 安装 Xen
Red Hat 公司在 RHEL5 版本的 Linux 操作系统中正式加入了对 Xen 虚拟技术的支持.而在RHEL5 之前的 Linux 系统中安装 Xen 需要进行编译内核的工作,安装过程较为繁琐和复杂.
在 RHEL5 中安装 Xen 有多种方式：
方法一：在 RHEL5 安装时输入包含支持 virtualization 的功能的安装号,系统默认会自动安装Xen 相关软件包.
方法二：在 RHEL5 的安装光盘中已包含全部 Xen 的软件包, 完全可以手动安装 RHEL5安装光盘中的 Xen 相关软件包, 需要安装软件包较多,此方法比较繁琐,不建议初学者使用.
方法三：在能连入互联网的前提下,使用 RHEL5 订阅号,利用 yum 工具安装 Xen 内核补丁、Xen 虚拟机、virt-manager 虚拟化管理工具.
方法四：利用 RHEL5 的 DVD 安装光盘构建本地 yum 安装源,利用 yum 工具安装 Xen 内核补丁、Xen 虚拟机、virt-manager 虚拟化管理工具.
这里推荐使用第四种方法进行安装.
现在以一个已安装 GNOME 图形桌面,已安装 Apache,但没有安装任何 Xen 软件的 RHEL5系统为例讲解如何安装 Xen 虚拟化软件.
拥有帝国一切，皆有可能。欢迎访问phome.net
 参照 http://jiayf.blog.51cto.com/1659430/342416 构建本地 yum 安装源,过程这里不再赘述.构建完成后执行以下命令安装 Xen 内核补丁、Xen 虚拟机、virt-manager 虚拟化管理工具
