VMWareMetadata is not called anywhere.

It looks like it was last modified for conversion to binary_struct here: 00a7dd423c738574008fe1895a5e19f27e32ac98

And the last substantial change was in 2009 here:
05d517b984ea1ecd89793063ece88ebd0be97927

The test contains invalid ruby 1.9 syntax, see below, and also contains binary string literals that may cause issues in ruby 2.0+.
