G4NDL3.15 does have Yttrium tables included. You can download this version (though I don't know if you can install it on a VM) from the GEANT4 9.5beta download area, http://www.geant4.org/geant4/support/download_beta.shtml

You should be able to use it with 9.4 by changing the G4NEUTRONHPDATA environment variable value.
