The above basically come down to the fact that currently virt-v2v does the copy first and the v2v step second. It was my understanding [Matt?] that guestconv is supposed to do the v2v step first followed by the copy, which should solve all of that. > Another issue with virt-v2v is that it _always_ tries to add virtio > drivers.
