‘vagrant up’ fails to mount linked directory /vagrant

偶然出现错误:

Failed to mount folders in Linux guest. This is usually because
the "vboxsf" file system is not available. Please verify that
the guest additions are properly installed in the guest and
can work properly. The command attempted was:

mount -t vboxsf -o uid=`id -u vagrant`,gid=`getent group vagrant | cut -d: -f3` vagrant /vagrant
mount -t vboxsf -o uid=`id -u vagrant`,gid=`id -g vagrant` vagrant /vagrant

The error output from the last command was:

/sbin/mount.vboxsf: mounting failed with the error: No such device

#再來就是安裝 VirtualBox Guest Additions kernel modules

[[email protected] ~]# /etc/init.d/vboxadd setup
Removing existing VirtualBox DKMS kernel modules           [  OK  ]

再來就可以重新啟動 Guest OS 確認啟動過程，應該就可以正常掛載 /vagrant 目錄了。

$ vagrant reload
