XEN 第一天

cat /proc/cpuinfo | grep flags

cat /etc/redhat-release  版本

rpm -qa | grep xen

cat /proc/cpuinfo | more

A:安装 XEN 核心
yum install xen kernel-xen

xen-3.03-105.el5_5.5 XEN 工具套件
kernel-xen-2.6.18 核心
Virt-manager-0.6.1-l2.el5 虚拟管理工具
Virt-viewer-0.0.2-3.el5       图形终端

mount -o loop /data/centos-5.5-i386-bin-DVD.sio /mnt/iso
ls /boot/

B：图形脂管理工具
yum install virt-manage  virt-viewer

创建Xen虚拟系统安装树
yum install httpd

VNC Server
yum -y install vnc-server

vpcpasswd
123
123

vi /etc/sysconfig/vncservers
VNCSERVERS="2:root"
VNCERVERARGS[2]="-geometry 800*600"
:wq

service vncserver start
service vncserver stop
ls .vnc/
service vncserver start

vi ./xstartup
unset SESSION_MANAGER
exec /etc/X11/xinit/xintrc

service  vncserver restart

 

C：看安装后产生的内核文件
