I have created following entry for a shred filesystem between host and guest:

  filesystem {
    source = "/home/chris/shared"
    target = "shared"
    readonly = false
  }

and mounted it via

mount -t  9p -o trans=virtio,version=9p2000.L,rw shared /srv/shared

but the filesystem is readonly.

The qemu run is also missing the right option:
