I'm using VirtualBox with OS X as host and CentOS on the guest VM.

In OS X I created folder myfolder, added it as shared folder to the VM, turned on the VM, in CentOS created folder /home/user/myfolder and typing:

sudo mount -t vboxsf myfolder /home/user/myfolder

and have output:

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

What I'm doing wrong?

UPDATED:

Guest Additions installed.

My shared folder/clipboard stopped to work for some reason (probably due to a patch installation on my virtual machine).

sudo mount -t vboxsf Shared_Folder ~/SF/

Gave following result:

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

The solution for me was to stop vboxadd and do a setup after that:

cd /opt/VBoxGuestAdditions-*/init  
sudo ./vboxadd setup
