Is sharing a folder for a Linux (Ubuntu) VM supposed to work?

[Tazintosh]

Hi,

I've setup an Ubuntu server 24.04.3 VM.
My VirtualBuddy VM's settings are set to share a folder from my Mac (actually a folder from connected external drive /Volumes/Storage/WIP).

I've done the following:

sudo mkdir /mnt/WIP
sudo mount -t virtiofs WIP /mnt/WIP

I'm getting the following error:
mount: /mnt/WIP: wrong fs type, bad option, bad superblock on WIP, missing codepage or helper program, or other error.

Any idea?
Thanks a lot in advance for your time.
