xen3.4.3源码编译

xen3.4.3源码编译

---

1. Xen Hypervisior安装

安装必备软件包

# yum groupinstall "Development Tools"

# yum install hmaccalc ncurses-devel zlib-devel openssl-devel python-devel \

bridge-utils  libtool-ltdl iasl xorg-x11-drv-evdev xorg-x11-drv-fbdev \

xorg-x11-drv-i810-devel xorg-x11-drv-via-devel xorg-x11-proto-devel \

xorg-x11-server-sdk xorg-x11-xtrans-devel

 

下载xen源码：

wget http://bits.xensource.com/oss-xen/release/3.4.3/xen-3.4.3.tar.gz

tar zxvf xen-3.4.3.tar.gz

cd xen-3.4.3

使用make world可以一次性安装，但是脚本会自动下载一个Kernel，过程比较慢，执行下面的命令可以加快编译速度：

make xen

make tools

make stubdom

make install-xen

make install-tools

make install-stubdom

为了简单，直接执行：

make world

编译完成后，执行：make install，这样就完成了Xen Hypervisior安装。

编译完成后，发现/boot目录下多了下面的文件

vmlinuz-2.6.18.8-xen
xen-3.4.3.gz
config-2.6.18.8-xen
xen-3.4.gz
xen-3.gz
xen.gz
System.map-2.6.18.8-xen

2. 发现没有自动创建inird文件，手动创建
cd linux-2.6.18-xen.hg/
mkinitrd initrd-2.6.18.8-xen.img .
cp initrd-2.6.18.8-xen.img /boot/

grub配置：
title CentOS (2.6.18.8-xen-mybuild)
     root (hd0,0)
     kernel /boot/xen-3.4.3.gz
     module /boot/vmlinuz-2.6.18.8-xen ro root=LABEL=/ rhgb quiet
     module /boot/initrd-2.6.18.8-xen.img

3. 启动虚机，发现模块错误，无法启动，需要重新编译内核

cd xen-3.4.3/linux-2.6.18-xen.hg/

$ make menuconfig

# cd /boot

grub配置：
title CentOS (2.6.18.8-xen-mybuild)
     root (hd0,0)
     kernel /boot/xen-3.4.3.gz
     module /boot/vmlinuz-2.6.18.8-xen ro root=LABEL=/ rhgb quiet
     module /boot/initrd-2.6.18.8-xen.img

启动成功

通过yum安装xen3.4.3

---

yum install xen kernel-xen即可。

安装后的grub：

title CentOS (2.6.18-274.7.1.el5xen)
     root (hd0,0)
     kernel /boot/xen.gz-3.4.3
     module /boot/vmlinuz-2.6.18-274.7.1.el5xen ro root=LABEL=/ rhgb quiet
     module /boot/initrd-2.6.18-274.7.1.el5xen.img
