vagrantの起動時に以下のように出た場合の対処方法。
HostOS:Windows10
GuestOS:CentOS7
VirtualBox:5.1.4
Vagrant:1.8.5
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 attemped was: set -e 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 command was: /sbin/mount.vboxsf: mounting failed with the error: No such device
guestにsshでログインして、

この状態になったら、hostで
vagrant halt vagrant up
