So in this case s.th. like:

* How can I mount a directory from the host in a QEMU VM.

  Use the 9pfs filesystem with a domain xml like:

    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/direcgory/on/host'/>
      <target dir=share'/>
    </filesystem>

  and to mount it within the guest use:

  cat <<EOF > /etc/fstab
      share /mnt/share  9p  trans=virtio,rw,_netdev 0       0
  EOF
  mount /mnt/share
     
  See https://libvirt.org/formatdomain.html#elementsFilesystems for
  details.

Or maybe we want to have more like a "How do I switch from VirtualBox to
QEMU" section?

What I'd like to understand is what motivated you to submit the patch.
I'm pretty sure we need to improve on the docs, just trying to figure
out _where_.

Cheers,
