[AB]:  Unfortunately I could not find any way to perform this rather than accomodating it inside libvirt. As mentioned more of the issue is: OVA installation is handled by hypervisor in more than one step, they do not expose specific APIs to load compressed disk associated with one VM, please correct me if my understanding is wrong here. It means then this feature could be blessed within libvirt framework at all :(.
 
For educational purpose, I want to ask why is "OVA installtion" is considered so alien. To me it is one of the ways to manage VM distribution in an hypervisor agnostic way.
  
Thanks!
