virtualbox共享文件夾

主機：windows 8

虛擬機：ubuntu server 12.04（沒有圖形化界面）

一、掛載Virtualbox的增長鏡像

二、在ubuntu中掛載此iso

enyo@UBUNTU /media$ sudo mount /dev/cdrom /media/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
enyo@UBUNTU /media$ ls /media/cdrom/
32Bit        autorun.sh  runasroot.sh              VBoxWindowsAdditions-amd64.exe
64Bit        cert        VBoxLinuxAdditions.run    VBoxWindowsAdditions.exe
AUTORUN.INF  OS2         VBoxSolarisAdditions.pkg  VBoxWindowsAdditions-x86.exe

三、安裝加強功能

enyo@UBUNTU /media$ sudo cdrom/VBoxLinuxAdditions.run 
Verifying archive integrity... All good.
Uncompressing VirtualBox 4.3.2 Guest Additions for Linux............
VirtualBox Guest Additions installer
Copying additional installer modules ...
Installing additional modules ...
Removing existing VirtualBox non-DKMS kernel modules ...done.
Building the VirtualBox Guest Additions kernel modules
The headers for the current running kernel were not found. If the following
module compilation fails then this could be the reason.

Building the main Guest Additions module ...done.
Building the shared folder support module ...done.
Building the OpenGL support module ...done.
Doing non-kernel setup of the Guest Additions ...done.
Starting the VirtualBox Guest Additions ...done.
Installing the Window System drivers ...fail!
(Could not find the X.Org or XFree86 Window System.)

enyo@UBUNTU /mnt$ sudo reboot

雖然有報錯說沒有桌面環境，可是不影響共享文件夾，重啓設置共享文件夾便可

四、設置共享文件夾

五、掛載共享文件夾

enyo@UBUNTU /media$ sudo mkdir myshare
enyo@UBUNTU /media$ sudo mount -t vboxsf myshare myshare

六、開機自動掛載文件夾

網上不少教程說把下面的代碼加入/etc/fstab，重啓便可

myshare /media/myshare vboxsf rw,gid=100,uid=1000,auto 0 0

可是系統調用fstab的時候，Virtualbox的共享目錄的模塊尚未加載，因此每次加載都會失敗，個人解決辦法是在在/etc/rc.local文件中加入一行

mount -t vboxsf myshare myshare

從新啓動便可實現自動掛載
