This is the core of the issue. Import of Debian based distributions is
not yet available in virt-v2v, unless you want to package it yourself.

Unfortunately that is not possible with virt-v2v.

Yes, it is. With 0.1.126 being the latest stable version.

You should have this repo in the ovirt-*-dependencies.repo file
installed as part of oVirt.

    [virtio-win-stable]
    name=virtio-win builds roughly matching what was shipped in latest RHEL
    baseurl=http://fedorapeople.org/groups/virt/virtio-win/repo/stable
