sorry. VBox was working fine and only when I decided to use
SharedFolders did I got this issue.

All I want to do is `mount.vboxsf Share /mnt/Share`. Maybe I do not
need to modprobe vboxvfs first... but I could not find anything. There
is no man page for mount.vboxsf. So I simply tried:

$ mkdir /tmp/vboxshared
$ sudo mount -t vboxsf shared /tmp/vboxshared
/sbin/mount.vboxsf: mounting failed with the error: No such device

Some search on the net suggest to actually do the (manual) `modprobe
vboxvfs` first. Should I modprobe vboxvfs first or not to get
mount.vboxsf working ?

Thanks !
