I untar'ed that OVA and inspected the OVF. The filter for that is:
     my $xpath_find_firmware = 
"/ovf:Envelope/ovf:VirtualSystem/ovf:VirtualHardwareSection/vmw:Config[\@vmw:key=\"firmware\"]/\@vmw:value";

The GNS3 OVF does have `vmw:Config` elements, though none for the 
firmware -> Default SeaBIOS

The CentOS OVF does not have any `vmw:Config` sub elements in that 
search path. That is probably what is causing the issue.
