vagrant upができない！

Question

「vagrant up」をすると、下記のエラーが発生します。
「vagrant ssh」はできるのですが、マウントができておらず、
Vagrantfileの「config.vm.synced_folder」が正常に処理されていないように見えます。

エラー発生原因と、Vagrantfileの改修方法が分かりません。
どなたか助けてください。

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=1000,gid=1000 vagrant /vagrant

The error output from the command was:

/sbin/mount.vboxsf: mounting failed with the error: No such device

同一エラーは発生していますが、
マウントできない件は、下記のコマンドを実行したら解決しました。

$ vagrant ssh
$ sudo yum update kernel
$ exit

Vagrantfileに追記して回避する方法はございますでしょうか？
