Xen4.4.1下载且安装
关闭selinux步骤省略
#Xen下载页面http://www.xenproject.org/downloads/xen-archives/xen-44-series/xen-441.html

编译内核
编译linux长期维护版内核linux-3.2.63
wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.2.63.tar.xz
tar xf linux-3.2.63.tar.xz
cd linux-3.2.63 #编译安装后此文件夹为5.4G,请提前准备磁盘空间
make menuconfig
1，进入 Processor type and features ---> Paravirtualized guest support --->[*] Xen guest support
2，进入Device Drivers ---> Block devices ---> <*> Xen virtual block device support
<*> Xen block-device backend driver
Device Drivers --->Xen driver support 把下面的都选上
3， Device Drivers ---> Network device support ---> <*> Xen network device frontend driver
<*> Xen backend network device
保存并开始安装
