安裝好Ubuntu 9.10後，運行Ubuntu並登錄。然後在VirtualBox的菜單裏選擇"設備(Devices)" -> "安裝增強功能包(Install Guest Additions)"。
你會發現在Ubuntu桌面上多出一個光盤圖標，這張光盤默認被自動加載到了文件夾/media/cdom0。進入命令行終端，輸入
sudo sh /media/VBOXADDITIONS_3.2.8_64453/VBoxLinuxAdditions-amd64.run 這是64bit的，如果是32bit 的則運行 sudo sh /media/VBOXADDITIONS_3.2.8_64453/VBoxLinuxAdditions-x86.run
@a-desktop:~$ sudo sh /media/VBOXADDITIONS_3.2.8_64453/VBoxLinuxAdditions-amd64.run
