xen目前还是RHEL/CentOS/OEL5.X支持情况比较好。RHEL6.X就默认不支持了，但是也可以通过安装xen的源进行安装。本文采用OEL5.8 x64进行环境配置。今后将发布一个系列的纯文本配置xen实战配置文章，这里不讨论半虚拟化，完全虚拟化等概念，只讲实战，以此对xen学习做一个总结。

1. 操作系统安装
采用OEL5.8 X64安装，安装过程中选中图形界面，开发包，开发库，老的软件开发包等，其它都不选。

# uname -a
Linux oradb 2.6.18-308.el5 #1 SMP Sat Feb 25 12:40:07 EST 2012 x86_64 x86_64 x86_64 GNU/Linux
2. 配置yum源
说明：通过安装源进行安装是最简单的。
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-el5.repo
# vi public-yum-el5.repo
#将对应的enable改为1,如下图所示

3. yum安装xen
# yum install kernel-xen xen-libs xen virt-viewer

4. 修改启动列表，使用运行xen的内核启动系统
# vi /boot/grub/grub.conf
说明: yum安装后，grub菜单是自动安装好了。
5. reboot 自动进入xen组件的内核。
# reboot
6. 查看xen启动情况
默认xen服务开机自启动
[root@node1 ~]# chkconfig --list |grep xend
xend 0:off 1:off 2:on 3:on 4:on 5:on 6:off
xendomains 0:off 1:off 2:off 3:on 4:on 5:on 6:off
查看xen内核
[root@node1 ~]# uname -a
Linux node1 2.6.18-348.16.1.0.1.el5xen #1 SMP Tue Aug 20 13:57:31 PDT 2013 x86_64 x86_64 x86_64 GNU/Linux
查看xen情况
[root@node1 ~]# xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 1744 1 r----- 32.8
到此xen虚拟化环境配置完毕，下面就开始安装虚拟机了。
