7.5 安裝Xen 主控端
Cobbler PXE菜單裡沒有關于Xen虛拟機的系統版本，導入CentOS5.8系統鏡像時，已經生成一個關于Xen的distros和profiles 即centos5.8-xen-x86_64，因為Cobbler知道它不可能PXE引導實體硬體。
如果你想安裝Xen 主控端，需要在安裝腳本ks檔案%packages部分添加xen包名 "kernel-xen"、“xen”。當然這樣似乎不太友善，你可以使用指令“cobbler import”再導入一個關于xenserver主控端的配置。
配置好ks檔案，安裝方法同步驟7.3。

yum install koan -y
