Vagrant で仮想マシンは起動できるのですが、共有フォルダのマウントに失敗しています。
発生しているエラー
default: /vagrant => [動かしている環境]
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=500,gid=500 vagrant /vagrant
The error output from the command was:
/sbin/mount.vboxsf: mounting failed with the error: No such device

ここでエラーを追うのはストップしようと思い Vagrant を再起動すると、共有フォルダがマウントされるようになりました。
$ vagrant halt
$ vagrant up
