[libvirt-users] no luck with filesystem storage type

[Boylan, Ross]

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.
