Sun VirtualBox安裝Ubuntu後與宿主系統共享文件

1.安裝好Ubuntu後點擊 Sun VirtualBox 的 設備->安裝增強功能
2.這個時候光驅中多了 VBOXADDITIONS_3 的光盤，進入光盤，運行autorun.sh
3.重啓之後，點 控制->自動調整顯示尺寸，這個時候ubuntu的分辨率已經可以隨虛擬機窗口自動變化
4.在Sun VirtualBox上點 設備->分配數據空間，新建一個數據空間，固定數據空間是永久，還有就是臨時的。
5.在gnome-terminal中運行命令sudo mount -t vboxsf my_dev /mnt/develop
其中my_dev是剛纔新建的數據空間的名字 /mnt/develop 是掛在點的名字。

至此，虛擬機就可以和宿主系統共享文件了。

裝好Ubuntu後還有很多設置工作了。
1)修改 /etc/apt/sources.list 軟件源配置，sudo cp /etc/apt/sources.list /etc/apt/sources.list_bak 備份一下，然後再sources.list裏面填上163，sohu等幾個國內的軟件源，這樣下載更新軟件就比較快。以下是我的sources.list文件裏面的內容

修改好之後 sudo apt-get update 刷新一下即可

2)設置拼音輸入法
9.10裏面默認是iBus輸入法，這個拼音輸入實在是不好用，裝回scim sudo apt-get install scim-chinese，輸入中文就舒服多了。
3)設置vim
先在新立得軟件管理器裏面搜索vim，安裝vim完整版，然後把我的vim配置文件.vimrc拷貝到~文件夾下面
