Puneet,

I'm guessing this is mostly some sort of shell quoting problem.  I will
add that you shouldn't use double backslashes to escape backslashes in
a .ovf file.  OVF files are XML and would only need XML styling escaping
internally.  So the SrcDataSource line should read:

   <SrcDataSource>"C:\My Documents\Data\foo.csv"</SrcDataSource>

I would encourage you to try your experiment in a path with no spaces
so you don't need so much quoting.

Best regards,
