I have seen problems with an out of date vhd-util, e.g. http://dlafferty.blogspot.co.uk/2013/08/using-cloudstacks-log-files-xenserver.html You could check that you are using the version of vhd-util you downloaded using "which vhd-util".
However, why don't you first rule out CIFS as the problem? Put the image on local storage, and try the command again.
