(Moving to devel-list)
BTW, I think that the import process should include a preliminary phase
where ovirt-engine is informed that the import process starts.

Currently, IIUC, the new process is designed to be:
1. virt-v2v uploads the disks
2. virt-v2v calls an API with the OVF configuration so ovirt-engine will
add the VM and attach the uploaded disks to that VM

IMHO, the process should be comprised of:
1. virt-v2v calls an API with the (probably partial since the OS and other
things are unknown at that point) OVF configuration
2. virt-v2v uploads the disks
3. virt-v2v provides the up-to-date configuration

Step #1 will enable ovirt-engine:
1. Most importantly, to cleanup uploaded disks in case of an error during
the import process. Otherwise, we require the client to clean them up,
which can be challenging (e.g., if the virt-v2v process crashes).
2. To inform the user that the process has started - so he won't get
surprised by seeing disks being uploaded suddenly. That will give a context
to these upload operations.
3. To inform the user about the progress of the import process, much like
we do today when importing VMs from vSphere to RHV.
4. To perform validations on the (partial) VM configuration, e.g.,
verifying that no VM with the same name exists/verifying there is enough
space (optionally mapping different disks to different storage devices) and
so on, before uploading the disks.

The gaps I see:
1. We don't have a command for step #1 yet but that's something we can
provide relatively quickly. We need it also to support uploading an OVA via
oVirt's webadmin.
2. We have a command for step #3, but it is not exposed via the API.
