7.5 安裝Xen 宿主機

Cobbler PXE菜單裏沒有關於Xen虛擬機的系統版本，導入CentOS5.8系統鏡像時，已經生成一個關於Xen的distros和profiles 即centos5.8-xen-x86_64，由於Cobbler知道它不可能PXE引導物理硬件。

若是你想安裝Xen 宿主機，須要在安裝腳本ks文件%packages部分添加xen包名 "kernel-xen"、「xen」。固然這樣彷佛不太方便，你可使用命令「cobbler import」再導入一個關於xenserver宿主機的配置。

配置好ks文件，安裝方法同步驟7.3。

yum install koan -y
