Build Xen & Lustre enabled kernel

• Our OS: Dbian etch
• Our Method:先使用xen patch過的kernel 2.6.18，之後在使用debian Lustre團隊的 patch file 來patch，將這新的kernel安裝至系統

1.必要套件

• Build kernel需要的:

  sudo aptitude install build-essential libncurses5-dev kernal-package
  

• Xne需要的:

  $ sudo apt-get install iproute bridge-utils python-twisted gcc binutils make zlib1g-dev python-dev transfig bzip2 \
      screen ssh debootstrap libcurl3-dev libncurses5-dev x-dev libsdl1.2-dev bin86 bcc python-pam patch latex-make \
      qemu qemu-launcher qemuctl graphviz graphviz-dev lvm2 libvncserver-dev libjpeg62-dev libjpeg62 gettext python-xml \
      gawk tetex-extra tetex-base openssl libssl-dev mercurial
  

• Lustre需要的:

  $ sudo aptitude install bzip2 debhelper dpatch libsnmp-dev module-assistant
  
  安裝 libxml
  $ sudo wget http://http.us.debian.org/debian/pool/main/libx/libxml2/libxml2_2.6.27.dfsg-2_i386.deb
  $ sudo dpkg -i libxml2_2.6.27.dfsg-2_i386.deb
  
  安裝 pyxml
  $ sudo wget PyXML-0.8.4.tar.gz
  $ sudo python setup.py build
  $ sudo python setup.py install
  

2.Patch和安裝kernel

• 下載Xen patch過的2.6.18 kernel和 Xen tar ball

  $ cd /usr/src
  $ sudo wget http://bits.xensource.com/oss-xen/release/3.2.1/xen-3.2.1.tar.gz
  $ sudo tar zxvf xen-3.2.1.tar.gz
  $ sudo hg clone http://xenbits.xensource.com/linux-2.6.18-xen.hg
  
  下載Debian Lustre 的 deb 檔 (http://packages.debian.org/source/sid/lustre)
  $ wget http://debian.linux.org.tw/debian/pool/main/l/lustre/linux-patch-lustre_1.6.5-1_all.deb
  $ wget http://debian.linux.org.tw/debian/pool/main/l/lustre/lustre-source_1.6.5-1_all.deb
  $ dpkg -i linux-patch-lustre_1.6.5-1_all.deb lustre-source_1.6.5-1_all.deb
  
  使用Lustre的patch file 來 patch xen kernel
  $ cd linux-2.6.18-xen.hg
  $ sudo ln -s /usr/src/kernel-patches/lustre/series/2.6.18-vanilla.series /usr/src/linux-2.6.18-xen.hg/series
  $ sudo ln -s /usr/src/kernel-patches/lustre/patches/ /usr/src/linux-2.6.18-xen.hg/.
  $ sudo quilt -av push
  

3.Make Xen image

$ cd /usr/src/xen-3.2.1
$ sudo make world
（SCSI disk I/O must build-in）
$ sudo make install
$ sudo update-grub

$ cd /usr/src/linux-2.6.18-xen.hg

$ sudo reboot
(choose xen image to booting)

4.Make Lustre modules

$ cd /usr/src/linux-2.6.18-xen.hg
$ sudo make menuconfig (make config)
$ sudo make -j 5
$ sudo make install
$ sudo make modules_install
$ sudo update-grub
$ sudo reboot
(choose new kernel booting)

$ cd /usr/src
$ sudo tar jxvf lustre.tar.bz2
$ cd module/lustre
$ sudo ./configure -with--linux=/usr/src/linux-2.6.18-xen.hg
$ sudo make
$ sudo make install

5.Test Xen & Lustre

startup xen 
$ sudo xend start
$ sudo xm list

startup Lustre
$ sudo modprobe ldiskfs
$ sudo modprob lnet
$ sudo mkfs.lustre -t lustre
