xen3.4.3源碼編譯

xen3.4.3源碼編譯

1. Xen Hypervisior安裝

安裝必備軟體包# 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 下載xen源碼：wget http://bits.xensource.com/oss-xen/release/3.4.3/xen-3.4.3.tar.gztar zxvf xen-3.4.3.tar.gzcd xen-3.4.3
使用make world可以一次性安裝，但是指令碼會自動下載一個Kernel，過程比較慢，執行下面的命令可以加快編譯速度：

make xen

make tools

make stubdom

make install-xen

make install-tools

make install-stubdom

為了簡單，直接執行：make world
編譯完成後，執行：make install，這樣就完成了Xen Hypervisior安裝。
編譯完成後，發現/boot目錄下多了下面的檔案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. 發現沒有自動建立inird檔案，手動建立
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. 啟動虛機，發現模組錯誤，無法啟動，需要重新編譯核心
cd xen-3.4.3/linux-2.6.18-xen.hg/
$ make menuconfig

$ make
$ make modules
# make modules_install
# make install
# depmod 2.6.18.8-xen# cd /boot# mkinitrd -v -f --with=sd_mod --with=scsi_mod initrd-2.6.18.8-xen.img 2.6.18.8-xen
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
啟動成功
通過yum安裝xen3.4.3

yum install xen kernel-xen即可。
安裝後的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
