libvirt users - Mar 2015 - no luck with filesystem storage type

I have a directory on the host that I would like to be visible in the
guest/domain.  Using virt-manager I selected the directory, resulting in this
configuration:
    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/mnt/SASInstaller'/>
      <target dir='/mnt/SASInstaller'/>
      <address type='pci' domain='0x0000' bus='0x00'
slot='0x08' function='0x0'/>
    </filesystem>
I created the /mnt/SASInstaller manually in the VM.

Nothing shows up.  What am I missing?  Do I need to run something in the VM
(running Linux) to make it work?

Thanks.

You need to mount it:

mount -t 9p /mnt/SASInstaller /mnt/SASInstaller

The target 'dir' is not really a directory, it's just a mount tag.
