It caught me by surprise as well while discussing [1].
Allon, has it been shared publicly? if not, can we publicly discuss the
high level design and goals of this effort?

We now enable triggering that process also via REST-API (this is mostly
intended for importing from VMware using ManageIQ, which is expected to be
available soon).

So besides using the REST-API mentioned above, we may be able to deliver
some of the stuff described in [1] before dropping the export domain. With
that, we can think of generating an oVirt-compatible OVA as an output of
virt-v2v that can be consumed in a similar way to how VMs in the export
domain used to be consumed.

Other than that, there is a rumor about introucing a backup-data-domain.
Hopefully, that plan will also be shared publicly and we'll know more
details about it. If it will be close in concept to the export domain, we
may be able to replace the export domain with that domain in virt-v2v.
