xen-4.1.2+Linux-3.1.2源码编译安装
以下所有命令均在CentOS6.2系统上操作。
下载xen源码
wget http://bits.xensource.com/oss-xen/release/4.1.2/xen-4.1.2.tar.gz
wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.1.2.tar.bz2
安装必备软件包
yum groupinstall "Development Libraries"
yum groupinstall "Development Tools"
yum install transfig wget texi2html libaio-devel dev86 glibc-devel e2fsprogs-devel gitk mkinitrd iasl xz-devel bzip2-devel pciutils-libs pciutils-devel SDL-devel libX11-devel gtk2-devel bridge-utils PyXML qemu-common qemu-img mercurial libidn-devel
yum -y install glibc-devel.i686texinfo libuuid-devel iasl python-lxml
yum -y install openssl openssl-devel
yum -y install ncurses ncurses-*
yum install python-devel -y
编译安装xen hypervisor
tar zxvf xen-4.1.2.tar.gz
make world
make install
/boot下多了xen-4.1.2.gz和xen-syms-4.1.2文件
将Xen加入到启动脚本：
/sbin/chkconfig --add xend/sbin/chkconfig --add xencommons/sbin/chkconfig --add xendomains/sbin/chkconfig xend on/sbin/chkconfig xendomains on/sbin/chkconfig xencommons on
编译安装Linux3.1.2内核
wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.1.2.tar.bz2
#make oldconfig # 全部默认
#make menuconfig
Processor type and features --- >
选中Paravirtualized Guest Support
Device Drivers --->
Xen driver support --->
全部选*
修改：CONFIG_XEN_DEV_EVTCHN=y（如果是m，开机时无法启动xencommons）
make
make modules
make modules_install
make install （会报找不到xen-evtchn模块，忽略）
make modules
make modules_install
make install （会报找不到xen-evtchn模块，忽略）
depmod 3.1.2
mkinitrd -v -f --with=aacraid --with=sd_mod --with=scsi_mod initramfs-3.1.2.img 3.1.2
配置grub：
title CentOS (3.1.2-xen)
root (hd0,0)
kernel /boot/xen-4.1.2.gz dom0_mem=1024M
module /boot/vmlinuz-3.1.2 ro root=/dev/sda1
module /boot/initramfs-3.1.2.img
root (hd0,0)
kernel /boot/xen-4.1.2.gz dom0_mem=1024M
module /boot/vmlinuz-3.1.2 ro root=/dev/sda1
module /boot/initramfs-3.1.2.img
