[Engine-devel] Forward comp[atibility of OVF

[Mike Kolesnik]

Hi, 

I wanted to know if we want to support forward compatibility of OVF format, which is used for export/import of VMs/VM Templates. 

For example, 
I create a VM in a 3.1 system, export it to an export Domain. 
Should I be able to import this VM on a 3.0 system? 

Obviously, backwards compatibility (from older version to newer) is desired and is kept , but do we really need forward compatibility also? 

The reason I'm asking is some changes that need to be done in current OVF format to support new features. These new changes will be backwards-compatible with old OVF formats, but is it desirable for them to be forward compatible? 


Regards, 
Mike
