as a first step, I have send patch to import external disk image.

now for ova import,
I think we need a method to extract files from ova (it's a simple tar file),

then an xml parser to parse OVF descriptor 

Does somebody known where are the specifications of config format ? does it have revisions ?

Only some experience: 

I was not able easily interchange simple OVA generated from VMware with OVA 
generated from VirtualBox without manual intervention. If you build 
something that works, that should be fine. I also tried to import OVA 
exported from VMware into Xen and it also did not work, not even with their 
support. Always some strange error. Whereas I never had problems importing 
into Proxmox VE.
