virtualbox挂载目录失败mount: unknown filesystem type ‘vboxsf’

[有小修改]

错误提示：
Vagrant was unable to mount VirtualBox shared folders. This is usually
because the filesystem “vboxsf” is not available. This filesystem is
made available via the VirtualBox Guest Additions and kernel module.
Please verify that these guest additions are properly installed in the
guest. This is not a bug in Vagrant and is usually caused by a faulty
Vagrant box. For context, the command attempted was:
mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant
The error output from the command was:

mount: unknown filesystem type ‘vboxsf’

 

一、打开
mac os => /Applications/VirtualBox.app/Contents/MacOS 

windows=> C:\Program Files\Oracle\VirtualBox
二、找到
VBoxGuestAdditions.iso
加载到虚拟机
若是没有能够到这里下载

http://download.virtualbox.org/virtualbox/5.2.8/VBoxGuestAdditions_5.2.8.iso

三、在虚拟机当中执行
sudo mount /dev/sr0 /media/cdrom
四、cd /media/cdrom/ && sh ./VBoxLinuxAdditions.run

五、reboot下虚拟机便可

 

安装还会遇到内核的问题，解决方法以下：

先 uname -r 看看内核版本

而后：

centos：  yum install kernel-devel-xxx

debian： apt install kernel-headers-xxx
