following code doesn't work :

 my $disk = VirtualDisk->new (capacityInKB => $size);



 my $devspec = VirtualDeviceConfigSpec->new(operation => VirtualDeviceConfigSpecOperation->new('add'),



         device => $disk,
        );




 my $cust_hardware = VirtualMachineConfigSpec->new (



         deviceChange => [$devspec] ,




 );



 my $clone_spec = VirtualMachineCloneSpec->new( 










 config => $cust_hardware, 



 );
