环境

• ArchLinux

步骤

1. 安装模块

   pacman -S virtualbox-guest-modules
   

2. 手动载入模块

   modprobe -a vboxsf
   

   若提示Module not found，则执行：

   depmod $(uname -r)
   

3. 开机自动载入模块

   echo vboxsf >/etc/modules-load.d/virtualbox.conf
   

4. 创建挂载点

   mkdir /data
   

5. 在虚拟机控制中，加入共享文件夹

   E_DRIVE
   

6. 挂载

   • 手动挂载

     mount -t vboxsf E_DRIVE /data
     

   • 自动挂载

     /etc/fstab
     
     E_DRIVE /data vboxsf
     

常见问题

• 挂载失败

  错误提示：

  [cpp] view plaincopy
  mount: wrong fs type, bad option, bad superblock on E_DRIVE,
         missing codepage or helper program, or other error
         (for several filesystems (e.g. nfs, cifs) you might
         need a /sbin/mount.<type> helper program)
         In some cases useful info is found in syslog - try
         dmesg | tail or so
  

  解决过程：

  1. dmesg | tail

     sf_read_super_aux err=-22

  2. 查看vboxsf链接

     vincent@vincent-VirtualBox:/mnt$ ls -al /sbin/mount.vboxsf
     lrwxrwxrwx 1 root root 40 Jun 19 09:38 /sbin/mount.vboxsf -> /usr/lib/VBoxGuestAdditions/mount.vboxsf
     

  3. 发现链接不对，重新链接

     ln -s /opt/VBoxGuestAdditions-4.3.10/lib/VBoxGuestAdditions/mount.vboxsf /sbin/mount.vboxsf
