[ubuntu_mate] qemu Shared Folder

I am trying to share a folder on my ubuntu 22.04 host and a folder on my ubuntu 22.04 qemu vm. On my host I have created /home/dad/vmhost and on the vm created /home/dad/hostshare

I have been following various gui (youtube) and text instructions. I get to the point on the vm where I type:

sudo mount -t 9p -o trans=virtio /sharepoint hostshare

when I enter that command I get:

mount: /home/dad/hostshare: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program.

Any advice appreciated.
