vagrant起動で"Failed to mount folders in Linux guest"のエラーが出た件
Windows7でvagrant環境を作ってあったので久々に起動したら以下のエラーが出たので、その時の対処法をメモしておきます。
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
環境
Windows7(ホストOS) CentOS6.6(ゲストOS) VirtualBox
対応
コマンドプロンプトを開き、Vagrantfileがあるディレクトリまで移動して、下記のコマンドを実行。
(この時一番上のエラーが出てたけどVM自体は起動していたかもしれません。)

うまく起動できました!
補足
同じエラーの解消方法を紹介しているサイト記事で /etc/init.d/vboxadd setup
でvboxをリビルドする、というものがいくつかありましたが、自分の環境ではこれでは直りませんでした。。
ちなみにGuest Additionとは、ホストOSとゲストOS間でマウスカーソルのシームレスに移動させたり、ホストOSとの時刻同期、ホストとゲストの共有フォルダ作成、などをサポートしてくれるモジュールのようです。
