Demo(二)：VMGL 操作手冊
【前言】
- 小叮嚀
- 請使用 gcc-4.1 來編譯 VMGL,勿使用 gcc-4.3.
- 必要時請切換 gcc 版本,可以使用 update-alternatives 或是重新建立 gcc 連結.
$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.1 1 $ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.3 2 $ sudo update-alternatives --config gcc
提供“gcc”的替換項式共有 2。 可使用的替換項目 ----------------------------------------------------- 1 /usr/bin/gcc-4.1 *+ 2 /usr/bin/gcc-4.3 按下 enter 來指定預設選項[*]，或者輸入選擇的號碼：1 Using '/usr/bin/gcc-4.1' to provide 'gcc'.
【Step 1: 在 pcXXX 上安裝 VMGL 】
- @pcXXX - 安裝環境所需套件.
$ sudo apt-get install build-essential firefox flashplugin-nonfree htop libao2 libasound2 libmikmod2 mesa-common-dev libglu1-mesa-dev mesa-utils libxmu-headers libxmu6 libxmu-dev zlib1g-dev libjpeg62 libjpeg62-dev xutils-dev libxext6 libxext-dev rxvt lwm tightvncserver xauth xvfb xfonts-100dpi xfonts-75dpi culmus xfonts-scalable xfonts-base
- @pcXXX - 下載VMGL.
$ wget http://www.cs.toronto.edu/~andreslc/software/vmgl-0.1.tar.bz2 $ tar jxvf vmgl-0.1.tar.bz2 $ cd ./vmgl.hg/tightvnc/
- @pcXXX - Patch for AMD64_Machine.
$ wget --no-check-certificate https://trac.nchc.org.tw/grid/raw-attachment/wiki/Xen_GPU_cluster/tightvnc-1.2.9-amd64support.patch $ patch -p0 < ../tightvnc/tightvnc-1.2.9-amd64support.patch
- @pcXXX - 設定編譯器路徑.
$ sudo ln -sf /usr/bin/make /usr/bin/gmake
- @pcXXX - 編譯.
$ cd .. ~/vmgl/vmgl.hg$ make
- @pcXXX - 安裝於 Dom0(host) 端上.
~/vmgl/vmgl.hg$ sudo make install-host
【Step 2:在 pcXXX 上建構一台 VMGL VM (vg01) 】
- @pcXXX - 設定你的虛擬機器.
$ sudo gedit /etc/xen-tools/xen-tools.conf
45 dir = /home 128 size = 4Gb # Disk image size. 129 memory = 256Mb # Memory size 130 swap = 128Mb # Swap size 132 fs = ext3 # use the EXT3 filesystem for the disk image. 133 dist = lenny # Default distribution to install. 134 image = sparse # Specify sparse vs. full disk images. 163 gateway = 192.168.100.254 164 netmask = 255.255.255.0 165 broadcast = 192.168.100.255 215 mirror = http://free.nchc.org.tw/debian
- @pcXXX - 產生你的虛擬機器.
$ sudo xen-create-image --hostname=vg01 --ip=192.168.100.X --mac=00:16:XX:XX:XX:XX --force
【Step 3: 確認虛擬機器(vg01)正確無誤】
$ sudo gedit /home/domains/vg01.cfg
9 kernel = '/boot/vmlinuz-2.6.22.9' 10 ramdisk = '/boot/initrd.img-2.6.22.9' 11 memory = '256' 12 vcpus = '4' # 不需配置顯示卡 # pci = ['01:00.0'] 16 root = '/dev/sda2 ro' 17 disk = [ 'file:/home/domains/nvidia/disk.img,sda2,w', 'file:/home/domains/nvidia/swap.img,sda1,w', ] 26 name = 'vg01' # # Networking # 31 vif = [ 'ip=192.168.100.X ,mac=00:16:XX:XX:XX:XX' ] # # Behaviour # 36 on_poweroff = 'destroy' 37 on_reboot = 'restart' 38 on_crash = 'restart'
【Step 4: 在 DomU(vg01) 上安裝 VMGL 】
- @Dom0 - 在 Dom0 上啟動虛擬機器 vg01 並登入.
$ cd /home/domains $ sudo xm create -c vg01.cfg
- @vg01 - 先用 root 免密碼登入 vg01, 然後新增使用者 clouder.
$ adduser clouder
Adding user `clouder' ... Adding new group `clouder' (1000) ... Adding new user `clouder' (1000) with group `clouder' ... Creating home directory `/home/clouder' ... Copying files from `/etc/skel' ... Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully Changing the user information for clouder Enter the new value, or press ENTER for the default Full Name []: Room Number []: Work Phone []: Home Phone []: Other []: Is the information correct? [Y/n] y
- @vg01 - 先登出 "root" 並且改用使用者 "clouder" 登入,接著安裝環境所需套件.
$ logout $ sudo apt-get install build-essential gcc-4.1 htop mozilla-plugin-vlc libao2 libasound2 libmikmod2 mesa-common-dev libglu1-mesa-dev mesa-utils libxmu-headers libxmu6 libxmu-dev zlib1g-dev libjpeg62 libjpeg62-dev xutils-dev libxaw7 libxaw7-dev libxext6 libxext-dev rxvt lwm vlc vlc-plugin-alsa tightvncserver udev ntpdate xauth xvfb xfonts-100dpi xfonts-75dpi culmus xfonts-scalable xfonts-base lxde openbox-themes gnome-settings-daemon gnome-settings-daemon-dev gnome-icon-theme wget
- @vg01 - 重新啟動虛擬機器.
$ sudo reboot
- 說明:輕量級桌面環境相關套件.
# Designed for lightweight X desktop support. xfonts-base xfonts-100dpi xfonts-75dpi -> fonts support rxvt -> x-terminal-emulator for VNC lwm -> x-window-manager for VNC openbox -> X-window-manager for VNC lxde -> Lightweight X11 Desktop Environment
- @vg01 - 下載VMGL.
$ mkdir vmgl $ cd ./vmgl ~/vmgl$ wget http://www.cs.toronto.edu/~andreslc/software/vmgl-0.1.tar.bz2 ~/vmgl$ wget http://trac.nchc.org.tw/grid/raw-attachment/wiki/Xen_GPU_cluster/tightvnc-1.2.9-amd64support.patch ~/vmgl$ tar jxvf vmgl-0.1.tar.bz2 ~/vmgl$ cd ./vmgl.hg/tightvnc/
- @vg01 - Patch for AMD64_Machine.
~/vmgl/vmgl.hg/tightvnc$ patch -p0 < ../../tightvnc-1.2.9-amd64support.patch ~/vmgl$ cd ..
- @vg01 - 設定編譯器路徑.
~/vmgl$ sudo ln -sf /usr/bin/make /usr/bin/gmake
- @vg01 - 先檢查 gcc 編譯器版本,並且選擇以下兩種變更方法.
$ gcc -v
- 方法一: @vg01 - 建立 gcc 連結.
$ sudo ln -sf /usr/bin/gcc-4.1 /usr/bin/gcc
- 方法二: @vg01 - 更換預設 gcc 版本,從 gcc-4.3 換成 gcc-4.1.
$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.1 1 $ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.3 2 $ sudo update-alternatives --config gcc
提供“gcc”的替換項式共有 2。 可使用的替換項目 ----------------------------------------------------- 1 /usr/bin/gcc-4.1 *+ 2 /usr/bin/gcc-4.2 按下 enter 來指定預設選項[*]，或者輸入選擇的號碼：1 Using '/usr/bin/gcc-4.1' to provide 'gcc'.
- @vg01 - 確認 gcc 編譯器 版本.
$ gcc -v
Using built-in specs. Target: x86_64-linux-gnu Configured with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.1.3 --program-suffix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --enable-mpfr --enable-checking=release x86_64-linux-gnu Thread model: posix gcc version 4.1.3 20080308 (prerelease) (Ubuntu 4.1.2-21ubuntu1)
- @vg01 - 建立安裝所需基本目錄.
~/vmgl/vmgl.hg$ sudo mkdir -p /usr/lib/xorg/modules/extensions
- @vg01 - 編譯.
~/vmgl/vmgl.hg$ make
- @vg01 - 安裝於 DomU(vg01) 端上.
~/vmgl/vmgl.hg$ sudo make install-guest
【Step 5: VMGL 使用說明: 在Dom0 上的設定】
- @pcXXX - 將 X-Windows 桌面 export 出來.
$ export DISPLAY=:0
- @pcXXX - 啟動 VLGL stub-daemon.
$ stub-daemon
- @pcXXX - 檢查 stub-daemon 所對應的 port(7000) 有無開啟.
$ netstat -tunlp

【Step 6: VMGL 使用說明: 在DomU 上的設定】
- @vg01 - 設定 DomU 上的字型路徑對應.
$ sudo mkdir -p /usr/X11R6/lib/X11/ $ sudo ln -sf /usr/share/fonts/X11/ /usr/X11R6/lib/X11/fonts
# FontPath: /usr/X11R6/lib/X11/fonts (新路徑) or /usr/share/fonts/X11 (系統預設路徑)
- @vg01 - 確認 rgb.txt 存在於相對應路徑.
$ sudo ln -sf /usr/share/X11/rgb.txt /usr/X11R6/lib/X11/rgb.txt $ cat /usr/X11R6/lib/X11/rgb.txt
- @vg01 - 切換為超級使用者.
$ sudo su -
- @vg01 - 設定 vg01 上的 VMGL 環境變數.
$ cat >> /etc/profile << EOF
- @vg01 - 逐一貼上以下設定.
GLSTUB=140.XXX.XXX.XXX:7000 LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/vmgl LD_PRELOAD=/usr/local/lib/vmgl/libGL.so export GLSTUB LD_LIBRARY_PATH LD_PRELOAD EOF
- @vg01 - 設定 DomU 上的 X forwarding.
$ echo "X11Forwarding yes" >> /etc/ssh/sshd_config
$ cat >> /etc/ssh/ssh_config << EOF
- @vg01 - 逐一貼上以下設定.
ForwardX11 yes ForwardX11Trusted yes EOF - @vg01 -返回使用者 "clouder".
$ exit
- @vg01 - 使環境變數生效.
$ source /etc/profile
- @vg01 - 重新啟動 DomU 上的 SSH Service.
$ sudo /etc/init.d/ssh restart
【Step 7: 在 Dom0 上 透過 X forwarding 登入 DomU 】
- 使用 X forwarding 的方式登入 DomU.
- @pcXXX - Using X forwarding.
$ ssh -X vg01
- @vg01 - 檢查 direct rendering 有無起來.

# Note: please do not run stub-daemon with "root" - @vg01 - 上的 glxgears 效能測試.
$ glxgears

【Step 8: 相關應用案例: VNC為例 】
- @vg01 - 設定VNC passwd.
$ vncpasswd
VNC directory /home/clouder/.vnc does not exist, creating. Password: Verify: Would you like to enter a view-only password (y/n)? n
- @vg01 - 先啟動一次 VNC server 來產生 vnc 相關設定檔.
$ vncserver
New 'X' desktop is vg01:1 Creating default startup script /home/clouder/.vnc/xstartup Starting applications specified in /home/clouder/.vnc/xstartup Log file is /home/clouder/.vnc/vg01:1.log - @vg01 - VNC 設定檔產生完成後即可先關閉該 VNC server.
$ vncserver -kill :1
- @vg01 - 修改 VNC 設定檔 xstartup,使得虛擬機器預設桌面使用 LXDE 來啟動.
$ cd $ echo "startlxde &" >> .vnc/xstartup
- @vg01 - 啟動一台 VNC server 並設定解析度.
$ vncserver -geometry 1024x768 -depth 24 :1
- @pcXXX - 安裝 VNC viewer.
$ sudo apt-get install xtightvncviewer
- @pcXXX - 執行 VNC viewer,來連結到由 DomU 所產生的虛擬桌面.
$ vncviewer vg01:1
- @vg01 - Kill 掉 VNC server 的方法.
$ vncserver -kill :1
