FreeBSD mount failed with error: operation not supported by device

Question

I'm using freeBSD on VirtualBox on Windows10.
I want to mount on Windows. (HOST:Windows GUEST:freeBSD)
I run mount command but got an error below.

mount -t vboxvfs -w mp /mnt/vbox
mount: mp: Operation not supported by device

How can I solve this error?

What I did:

I install virtualbox-ose-additions-nox11-5.2.34 and virtualbox-ose-kmod-5.2.34,
then append vboxguest_enable="YES" and vboxservice_enable="YES" to my /etc/rc.config.

mp is normal empty folder on C:

I also install Guest Additions following Virtualbox's dialog.

Answer 1

this error caused by typo.

wrong : vboxfs
correct: vboxvfs

(I write correct command in this Question but I enter wrong command to my machine.)
