1.安裝 Xen-patched Kernel

• ​下載 Xen-patched Kernel

  $ sudo dpkg -i linux-xen0-2.6.22.9-rock_2.6.22-16.61_amd64.deb
  $ sudo mv linux-xen0-2.6.22.9-rock vmlinuz-2.6.22.9-rock
  $ sudo mkinitramfs -o /boot/initrd.img-2.6.22.9-rock 2.6.22.9-rock

2.安裝 Xen Image & tools

• ​下載 Xen Source

  $ cd /usr/src
  $ sudo wget http://bits.xensource.com/oss-xen/release/3.3.1/xen-3.3.1.tar.gz
  $ sudo tar zxvf xen-3.3.1.tar.gz
  
  $ cd xen-3.3.1
  $ sudo make -j 4 xen 
  $ sudo  make -j 4 tools
  $ sudo make install-xen 
  $ sudo make install-tools
  

• 編輯 Grub Menu

  $ sudo vim /boot/grub/menu.lst
  
  title           Xen 3.3.1 , kernel 2.6.22.9-rock
  kernel          /boot/xen-3.3.1.gz
  module          /boot/vmlinuz-2.6.22.9-rock root=/dev/sda1 ro quiet splash      
  module          /boot/initrd.img-2.6.22.9-rock

5. 製作 VM Image

5.1 自行使用工具製作

• 安裝 xen-tools

  $ cd
  $ wget http://www.xen-tools.org/software/xen-tools/xen-tools-4.1.tar.gz
  $ tar zxvf xen-tools-4.1.tar.gz
  $ cd xen-tools-4.1
  $ sudo make install
  
  $ sudo vim /etc/xen-tools/xen-tools.conf
  dir = /home
  gateway   = X.X.X.X
  netmask   = X.X.X.X
  broadcast =  X.X.X.X
  

• 產生 VM Image

  $ sudo xen-create-iage --hostname xen01 --ip X.X.X.X 
  

• 啟動 VM

  $ cd /etc/xen
  $ sudo xm create -c xen01 
  

5.2 使用其他團隊已做好的 Image

• 可從以下網站，下載 Image (這些網站將其稱為 virtual appliance)，最底下兩個是要付費的
  • ​jailtime.org
  • ​Virtual Appliances blog
  • ​rpath online
  • ​jumpbox
• 練習

  $ wget http://virtualappliances.net/download/archive/VirtualAppliancesLAMP-xen-1.0.113.tar.bz2
  $ tar jxvf VirtualAppliancesLAMP-xen-1.0.113.tar.bz2
  $ cd VirtualAppliancesLAMP 
  $ vim VirtualAppliancesLAMP.cfg
  $ sudo xm create -c VirtualAppliancesLAMP.cfg
