xen目前還是RHEL/CentOS/OEL5.X支持情況比較好。RHEL6.X就默認不支持了，但是也可以通過安裝xen的源進行安裝。本文采用OEL5.8?x64進行環境配置。今后將發布一個系列的純文本配置xen實戰配置文章，這里不討論半虛擬化，完全虛擬化等概念，只講實戰，以此對xen學習做一個總結。

4.?修改啟動列表，使用運行xen的內核啟動系統?

#?vi?/boot/grub/grub.conf

說明:?yum安裝后，grub菜單是自動安裝好了。?

?

5.?reboot?自動進入xen組件的內核。?

#?reboot?

?

6.?查看xen啟動情況?

默認xen服務開機自啟動???
