This piece of code seems suspect to me

 # find all the entities in the current file
  if (/entity\s+(\w+)\s+is/i) {
    $1{'name'} = $1;
    $1{'fname'} = $vhd_file;
    push @entities, \%1;
  }
[download]

I think it should be something like

   push @entities, \%{$1};
[download]

perhaps using the Data::Dumper module would help to debug it, also I would use a hash of hashes rather than a separate hash for each entity.

use Data::Dumper;
....
 # find all the entities in the current file
  if (/entity\s+(\w+)\s+is/i) {
    $hash{$1}{'name'} = $1;
    $hash{$1}{'fname'} = $vhd_file;
    push @entities, $1;
  }  
....
close VHD;
}

print Dumper(%hash);

Hope this is of some use Ay_Bee
