vagrant upで共有フォルダをマウントできない場合
こんな感じになった場合
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
VirtualBox Gest Additionsのビルドに失敗→起動できていないようなので、vboxadd setupすれば良いらしい
$ sudo /etc/init.d/vboxadd setup Removing existing VirtualBox non-DKMS kernel modules [ OK ] Building the VirtualBox Guest Additions kernel modules Building the main Guest Additions module [ OK ] Building the shared folder support module [ OK ] Building the OpenGL support module [ OK ] Doing non-kernel setup of the Guest Additions [ OK ] Starting the VirtualBox Guest Additions [ OK ]
ただし、kernel moduleをビルドするためにはkernel-develが必要
$ sudo yum install kernel-devel
