實作八：VMGL 實作
【Step 1: 在 Dom0 上安裝 VMGL 】
- 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
- 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/
- 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-1.2.9-amd64support.patch
- 設定編譯器路徑.
$ sudo ln -sf /usr/bin/make /usr/bin/gmake
- 編譯.
~/vmgl/vmgl.hg$ make
- 安裝於 Dom0(host) 端上.
~/vmgl/vmgl.hg$ sudo make install-host
【Step 2: 建構一台 VMGL VM (vg01) 】
- 設定你的虛擬機器.
$ sudo vim /etc/xen-tools/xen-tools.conf
dir = /home install-method = debootstrap size = 4Gb # Disk image size. memory = 256Mb # Memory size swap = 128Mb # Swap size fs = ext3 # use the EXT3 filesystem for the disk image. dist = hardy # Default distribution to install. ---> For CUDA Support (Ubuntu 8.0.4) image = sparse # Specify sparse vs. full disk images. gateway = 192.168.100.254 netmask = 255.255.255.0 broadcast = 192.168.100.255 kernel = /boot/vmlinuz-`uname -r` initrd = /boot/initrd.img-`uname -r` mirror = http://free.nchc.org.tw/ubuntu/ ext3_options = noatime,nodiratime,errors=remount-ro ext2_options = noatime,nodiratime,errors=remount-ro xfs_options = defaults reiser_options = defaults
- 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 vim /etc/xen/vg01.cfg
kernel = '/boot/vmlinuz-2.6.22.9' ramdisk = '/boot/initrd.img-2.6.22.9' memory = '256' vcpus = '4' # 不需配置顯示卡 # pci = ['01:00.0'] root = '/dev/sda2 ro' disk = [ 'file:/home/domains/nvidia/disk.img,sda2,w', 'file:/home/domains/nvidia/swap.img,sda1,w', ] name = 'vg01' # # Networking # vif = [ 'ip=192.168.100.X ,mac=00:16:XX:XX:XX:XX' ] # # Behaviour # on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart'
【Step 4: 在 DomU(vg01) 上安裝 VMGL 】
- 在 Dom0 上啟動虛擬機器 vg01 並登入.
$ sudo xm create -c vg01.cfg
- 啟動完成後,使用者便可以在遠端透過 ssh 的方式登入 vg01.
$ ssh xxx.xxx.xxx.xxx
- 安裝環境所需套件.
~$ sudo apt-get install build-essential firefox flashplugin-nonfree 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 libxaw-headers libxaw7 libxaw7-dev libxext6 libxext-dev rxvt lwm vlc vlc-plugin-alsa tightvncserver xauth xvfb xfonts-100dpi xfonts-75dpi culmus xfonts-scalable xfonts-base
- 基本桌面環境.
# Desgin for lightweight X support xfonts-base xfonts-100dpi xfonts-75dpi -> fonts support rxvt -> x-terminal-emulator for VNC lwm -> x-window-manager for VNC
- 下載VMGL.
$ mkdir -p 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/
- Patch for AMD64_Machine.
~/vmgl/vmgl.hg/tightvnc$ patch -p0 < ../../tightvnc-1.2.9-amd64support.patch ~/vmgl$ cd ..
- 設定編譯器路徑.
~/vmgl$ sudo ln -sf /usr/bin/make /usr/bin/gmake
- 建立安裝所需基本目錄.
~/vmgl/vmgl.hg$ sudo mkdir -p /usr/lib/xorg/modules/extensions
- 編譯.
~/vmgl/vmgl.hg$ make
- 安裝於 DomU(vg01) 端上.
~/vmgl/vmgl.hg$ sudo make install-guest
- 修正 rgb PATH 問題.
~/vmgl/vmgl.hg$ sudo mkdir -p /usr/X11R6/lib/X11 ~/vmgl/vmgl.hg$ sudo ln -sf /etc/X11/rgb.txt /usr/X11R6/lib/X11/rgb
【Step 5: 在 DomU(vg01) 上安裝輕量級桌面環境(LXDE)】
- 切換身份為 Super user.
$ sudo su
- 加入 LXDE 的 source.
$ echo "deb http://ppa.launchpad.net/lxde/ubuntu hardy main" >> /etc/apt/sources.list $ echo "deb-src http://ppa.launchpad.net/lxde/ubuntu hardy main" >> /etc/apt/sources.list $ exit
- 安裝 LXDE.
$ sudo apt-get install lxde openbox-themes gnome-settings-daemon gnome-settings-daemon-dev gnome-icon-theme
- 預設 LXDE 為VNC桌面環境.
$ echo "startlxde &" >> .vnc/xstartup
- 基本桌面環境.
# Desgin for lightweight X support lxde -> Lightweight X11 Desktop Environment openbox -> X-window-manager for VNC
【Step 6: VMGL 使用說明: 在Dom0 上的設定】
- 將 X-Windows 桌面 export 出來.
$ export DISPLAY=:0
- 啟動 VLGL stub-daemon.
rider@cloud:~$ stub-daemon
- 檢查 stub-daemon 所對應的 port(7000) 有無開啟.
$ netstat -tunlp
Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:8002 0.0.0.0:* LISTEN - tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN - tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN - tcp 0 0 0.0.0.0:7000 0.0.0.0:* LISTEN 29082/stub-daemon ---> VMGL stub-daemon udp 0 0 0.0.0.0:32769 0.0.0.0:* - udp 0 0 0.0.0.0:5353 0.0.0.0:* -
【Step 7: VMGL 使用說明: 在DomU 上的設定】
- 設定 DomU 上的字型路徑對應.
$ sudo ln -sf /usr/share/fonts/X11/ /usr/X11R6/lib/X11/fonts
# FontPath: /usr/X11R6/lib/X11/fonts or /usr/share/fonts/X11 - 確認 rgb 存在於對應路徑.
$ less /usr/X11R6/lib/X11/rgb.txt
- 設定 DomU 上的 VMGL 環境變數.
$ sudo vim /etc/profile
GLSTUB=IP: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
$ source /etc/profile
- 設定 DomU 上的 X forwarding.
- Using X forwarding.
$ sudo vim /etc/ssh/sshd_config
X11Forwarding yes
$ sudo vim /etc/ssh/ssh_config
ForwardX11 yes ForwardX11Trusted yes - 重新啟動 DomU 上的 SSH Service.
$ sudo /etc/init.d/ssh restart
- 設定 VNC server 使用者密碼.
$ vncpasswd
- 啟動 VNC server.
$ vncserver
xauth: creating new authority file /root/.Xauthority New 'X' desktop is guest:1 Creating default startup script /root/.vnc/xstartup Starting applications specified in /root/.vnc/xstartup Log file is /root/.vnc/vg01:1.log - 關閉 VNC server.
$ vncserver -kill :1
- 設定 VNC server 啟動參數.
$ vim .vnc/xstartup
# xrdb $HOME/.Xresources - 開啟 DomU 上的第一台VNC Server,並指定解析度為 1024 x 768.
$ vncserver -geometry 1024x768 -depth 24 :1
- 檢查 VNCserver 有無開啟對應之 port(5901開始).
$ netstat -tunlp
(Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 10652/Xtightvnc ---> guest:1 tcp 0 0 0.0.0.0:5902 0.0.0.0:* LISTEN 10630/Xtightvnc tcp 0 0 0.0.0.0:6001 0.0.0.0:* LISTEN 10652/Xtightvnc ---> guest:2 tcp 0 0 0.0.0.0:6002 0.0.0.0:* LISTEN 10630/Xtightvnc tcp 0 0 127.0.0.1:6010 0.0.0.0:* LISTEN - tcp6 0 0 :::22 :::* LISTEN - tcp6 0 0 ::1:6010 :::* LISTEN -
- 將 VNC Server:1 export 出來.
$ export DISPLAY=:1
【Step 8: 在 Dom0 上 透過 X forwarding 登入 DomU 】
- 使用 X forwarding 的方式登入 DomU.
- Using X forwarding.
$ ssh -X guest
- 檢查 direct rendering 有無起來.
