KVM HA Access to Host File Directory

I have HA installed in KVM and working well. I mounted a KVM fileshare which points to the host /mnt directory where all of my media is stored.

How can I give HA access to that same host /mnt director in order for radarr/sonarr/plex add-ons to see/use the files within?

Maybe use virtiofs based filesystem passthrough? I have only played around with this but I have had success manually mounting a directory on the host to a HAOS mount point or within the homeassistant container’s /media directory. I haven’t put this into production so not sure how to do the mounting automatically.
