QEMU Mount host directory to home assistant VM

In my NAS I am hosting home assistant inside a QEMU VM, and I’d like to mount my ZFS pool into home assistant so I could write my Frigate recordings to it directly, instead of through a network NFS share.

I am using Cockpit UI, and I have created the following shared directory in the VM UI:

And now it says I need to do the following:

But no matter what I try, I always get this error:

➜  /media mount -t virtiofs pool /media/pool 
mount: /media/pool: cannot mount pool read-only.
       dmesg(1) may have more information after failed mount system call.

How can I make it work? Does HA even support it?
Thank you.
