I'm running Debian 9 as Host and I installed correctly Windows 7 as guest by using Oracle VirtualBox (v. 5.2.6); both the OSs work fine and I need to have a folder shared between those 2 operative systems.
In order to be able to get this, I followed these steps:
GuestAddition installation, by running, as super-user:
apt-get install virtualbox-guest-dkms virtualbox-guest-x11 linux-headers-$(uname -r)
Creating the candidate folder
/home/quant/Scrivania/VirtualBox/Databy modifying the Oracle VirtualBox Manager settings (Shared Folders);
mounting the device by running:
mount -t vboxsf Data /home/quant/Scrivania/VirtualBox/Data/
At the point (3), I got the following error message in the terminal:
/sbin/mount.vboxsf: mounting failed with the error: No such device
It seems like the folder does not exist although I manually create the local folder and set it as shared folder in the VirtualBox manager.
Someone could suggest a solution?
Hope I has been clear when I asked the question. Thanks you all in advice!
