[libvirt-users] 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. Ross Boylan
