The OVF specifications are here:
https://www.dmtf.org/standards/ovf

the problems is that the implementation of the spec varies between
hypervisors.
libguestfs and its associated virt-v2v tool support only ova imports
from Vmware, probably because of this.

seem than virt-manager have a virt-convert tool which is able to read ovf 

https://github.com/virt-manager/virt-manager/blob/master/virt-convert 

they are a lot of ovf sample configs in the repository.

Hi, 

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.

Hi, 

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),

I have this somewhere in my todo list although it is not high priority
at the momment.

I would like to try to following approach:
 * extract the OVA archive (itsel a tar) to get the OVF xml manifest and
the disk image
 * from the OVF xml file generate a minimal vm.conf
 * create a vma archive with the disk image and associated vm.conf using
the vma command
 * now you have a valid vzdump  ready to be extracted to the storage of
your choice with the tools you know already

stuff to be left out for first approach:

 * ova with multiple disk images (don't know if the vma command line
utils support that)

 * extraneous paramaters of OVF file. The OVF spec is 40 pages long and
allows vendor specific options via private xml namespaces. So we're not
going to cover all of it.

Any comments on this approach ?

Are there any plans of making a import function for OVA/OVF ?
I know it's doable with a lot of manual tinkering
