Vagrantでフォルダがmountできないエラーが出たときの対応
Vagrant で CentOS 6.5 を使っていたら Guest Additions の更新に失敗してハマった
その2
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
GuestAdditionsをインストールしたり再ビルドしたりする
