步驟二: 建構一台 VMGL Guest VM

# 設定你想要怎樣規格的虛擬機器.
rider@cloud:~$ sudo vim /etc/xen-tools/xen-tools.conf

dir = /home
install-method = debootstrap
size   = 8Gb      # Disk image size.
memory = 1024Mb    # 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   = 140.XXX.XXX.XXX
netmask   = 255.255.255.0
broadcast = 140.XXX.XXX.XXX
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

rider@cloud:~$ sudo xen-create-image --hostname guest --ip 140.XXX.XXX.XXX

步驟三: 設定虛擬機器(Guest)

rider@cloud:~$ sudo vim /etc/xen/nvidia.cfg

kernel      = '/boot/vmlinuz-2.6.22.9'
ramdisk     = '/boot/initrd.img-2.6.22.9'
 
memory      = '1024'
vcpus       = '4'

# 不需配置 PCIE 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        = 'nvidia'
 
#
#  Networking
#
vif         = [ 'ip=140.xxx.xxx.xxx,mac=00:16:3E:AA:70:5C' ]
 
#
#  Behaviour
#
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

步驟四: 在 DomU(Guest) 上安裝 VMGL

# 啟動虛擬機器Guest並登入.
# 方法一.
rider@cloud:~$ sudo xm create -c guest.cfg
# 方法二.
@Dom0
rider@cloud:~$ sudo xm create guest.cfg
@ClientUser
rider@PC:~$ ssh 140.xxx.xxx.xxx
# 安裝環境所需套件.
rider@guest:~$ mkdir -p vmgl
rider@guest:~$ cd ./vmgl
rider@guest:~/vmgl$ 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 basic windows support

xfonts-base xfonts-100dpi xfonts-75dpi -> fonts support
rxvt -> x-terminal-emulator for VNC
lwm  -> x-window-manager for VNC

# 下載VMGL.
rider@guest:~/vmgl$ wget http://www.cs.toronto.edu/~andreslc/software/vmgl-0.1.tar.bz2
rider@guest:~/v,gl$ wget http://trac.nchc.org.tw/grid/raw-attachment/wiki/Xen_GPU_cluster/tightvnc-1.2.9-amd64support.patch
rider@guest:~/vmgl$ tar jxvf vmgl-0.1.tar.bz2
rider@guest:~/vmgl$ cd ./vmgl.hg/tightvnc/
# Patch for AMD64_Machine.
rider@guest:~/vmgl/vmgl.hg/tightvnc$ patch -p0 < ../../tightvnc-1.2.9-amd64support.patch
rider@guest:~/vmgl$ cd ..
# 設定編譯器路徑.
rider@guest:~/vmgl$ sudo ln -sf /usr/bin/make /usr/bin/gmake (if necessary)
# 建立安裝所需基本目錄.
rider@guest:~/vmgl/vmgl.hg$ sudo mkdir -p /usr/lib/xorg (if necessary)
rider@guest:~/vmgl/vmgl.hg$ sudo mkdir -p /usr/lib/xorg/modules (if necessary)
rider@guest:~/vmgl/vmgl.hg$ sudo mkdir -p /usr/lib/xorg/modules/extensions (if necessary)
# 編譯.
rider@guest:~/vmgl/vmgl.hg$ make
# 安裝於 DomU(guest) 端上.
rider@guest:~/vmgl/vmgl.hg$ sudo make install-guest
# 修正 rgb PATH 問題.

## Fix the rgb_Path problem.
rider@guest:~/vmgl/vmgl.hg$ sudo mkdir -p /usr/X11R6/lib
rider@guest:~/vmgl/vmgl.hg$ sudo mkdir /usr/X11R6/lib/X11
rider@guest:~/vmgl/vmgl.hg$ sudo ln -sf /etc/X11/rgb.txt /usr/X11R6/lib/X11/rgb

步驟五: VMGL 使用說明: 在Dom0 上的設定

# 將 X-Windows 桌面 export 出來.
rider@cloud:~$ 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.
rider@cloud:~$ netstat -tunlp

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

udp        0      0 0.0.0.0:32769           0.0.0.0:*                           -

步驟六: VMGL 使用說明: 在DomU 上的設定

# 設定 DomU 上的字型路徑對應.
rider@guest:~$ sudo ln -sf /usr/share/fonts/X11/ /usr/X11R6/lib/X11/fonts (if necessary - fix font path)

# FontPath:

/usr/X11R6/lib/X11/fonts
or
/usr/share/fonts/X11

# 確認 rgb 存在於對應路徑.
rider@guest:~$ less /usr/X11R6/lib/X11/rgb.txt (if necessary - rgb path confirmation)
# 設定 DomU 上的 VMGL 環境變數.
rider@guest:~$ sudo vim /etc/profile

GLSTUB=Cloud_IP(host_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

rider@guest:~$ source /etc/profile
# 設定 DomU 上的 X forwarding.
Using X forwarding
rider@guest:~$ sudo vim /etc/ssh/sshd_config

X11Forwarding yes

rider@guest:~$ sudo vim /etc/ssh/ssh_config

    ForwardX11 yes
    ForwardX11Trusted yes

# 重新啟動 DomU 上的 SSH Service.
rider@guest:~$ sudo /etc/init.d/ssh restart
# 設定 VNC server 啟動參數.
rider@guest:~$ vim .vnc/xstartup

# xrdb $HOME/.Xresources

# 設定 VNC server 使用者密碼.
rider@guest:~$ vncpasswd
# 開啟 DomU 上的第一台VNC Server.
rider@guest:~$ vncserver -geometry 1024x768 -depth 24 :1
# 開啟 DomU 上的第二台VNC Server.(可跳過此步驟)
rider@guest:~$ vncserver -geometry 1024x768 -depth 24 :2
# 檢查 VNCserver 有無開啟對應之 port(5901開始).
rider@guest:~$ netstat -tunlp

# 將 VNC Server:1 export 出來.
rider@guest:~$ export DISPLAY=:1

步驟七: 在 Dom0 上 透過 X forwarding 登入 DomU

# 使用 X forwarding 的方式登入 DomU.
Using X forwarding
rider@cloud:~$ ssh -X guest
# 檢查 direct rendering 有無起來.
rider@guest:~$ glxinfo

# DomU 上的 glxgears 效能測試.
rider@guest:~$ glxgears

47819 frames in 5.0 seconds = 9563.678 FPS
46064 frames in 5.0 seconds = 9212.566 FPS
44584 frames in 5.0 seconds = 8916.581 FPS
44256 frames in 5.0 seconds = 8850.974 FPS
44688 frames in 5.0 seconds = 8937.528 FPS

步驟八: 使用 VNC Viewer 登入 DomU

# 透過 VNC Viewer(TurboVNC Viewer or Tightvnc viewer)登入 DomU 的 VNC Server,登入後便可以透過 rxvt 來下指令跑相關3D應用了.
@ ClientUser
rider@PC:~$ vncviewer guest:1
# 檢查 direct rendering=yes?.
@ VNC viewer 登入 :1 後
rider@guest:~$ glxinfo

實作四: 在虛擬機器上 - 體驗 3D 硬體加速

步驟九: 喀 Game 時間

# 開啟 Firefox 來玩 Doom Online.
rider@guest:~$ firefox http://necromanthus.com/Games/Flash/doom.html

步驟十: 賞 "片" 時間

rider@guest:~$ mkdir unigine
rider@guest:~$ mkdir ./unigine/avi
rider@guest:~$ cd ./unigine/avi
rider@guest:~/unigine/avi$ wget http://mail.pdaxrom.org/unigine.com/Unigine_Tropics_640x360.avi
rider@guest:~/unigine/avi$ wget http://unigine.com/download/video/Unigine_Tropics_1024x576.avi
# 在 rxvt 叫出 VLC 來播放測試影片.
rider@guest:~/unigine/avi$ vlc Unigine_Tropics_640x360.avi

# 有興趣的也可以在行動裝置上使用 VNC Viewer or VLC 來實驗看看.

步驟十一: Firefox Cooliris 嘗鮮

# 打開 Firefox 打開"工具" -> "附加元件" -> "取得元件" -> 搜尋並安裝"cooliris" -> 重新啟動 Firefox.
# 若有問題請執行以下步驟.
rider@guest:~$ mkdir -p .mozilla/plugins
# 下載 Adobe 64-bit Flash Player 10 plugin.
rider@guest:~$ wget http://download.macromedia.com/pub/labs/flashplayer10/libflashplayer-10.0.22.87.linux-x86_64.so.tar.gz
rider@guest:~$ tar -zxvf libflashplayer-10.0.22.87.linux-x86_64.so.tar.gz -C ~/.mozilla/plugins
# Check 有無遺失 Librady 或路徑有誤.
rider@guest:~$ ldd ~/.mozilla/firefox/xc8lwx2j.default/extensions/piclens@cooliris.com/libs-64/libcooliris19.so
rider@guest:~$ ldd ~/.mozilla/firefox/xc8lwx2j.default/extensions/piclens@cooliris.com/libs-64/libav.so
# 安裝所需 Library , 並建立 linking.
rider@guest:~$ sudo apt-get install libmozjs0d libmozillainterfaces-java xulrunner-1.9 libxsltc-java libxslt1.1 xulrunner rider@guest:~$ sudo ln -sf /usr/lib/libxpcom.so.0d /usr/lib/libxpcom.so
rider@guest:~$ sudo ln -sf /usr/lib/libmozjs.so.0d /usr/lib/libmozjs.so
rider@guest:~$ sudo ldconfig
# Restart Firefox.

步驟十二: Dom0 OpenGL 3.0 效能實測

# 使用工具: "Unigine Tropics" or "NVIDIA PerfKit" 來測試 NVIDIA OpenGL 3.0 效能
# 使用 Tropics.
rider@cloud:~$ mkdir unigine
rider@cloud:~$ cd ./unigine
rider@cloud:~/unigine$ wget http://unigine.com/download/files/Unigine_Tropics-1.1.tar.bz2
rider@cloud:~/unigine$ mv Unigine_Tropics-1.1.tar.bz2\?noredirect Unigine_Tropics-1.1.tar.bz2
rider@cloud:~/unigine$ tar jxvf Unigine_Tropics-1.1.tar.bz2
rider@cloud:~/unigine$ cd ./Unigine_Tropics-1.1/
# 播放 1024x768 的影片來作 Benchmark.
rider@cloud:~/unigine/Unigine_Tropics-1.1$ ./windowed_1024x768.sh
