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

Complete!

 

4. 修改启动列表,使用运行xen的内核启动系统 

# vi /boot/grub/grub.conf

2
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。
