Guests consist of the disk images, plus copious metadata.
When you give just the disk image to virt-v2v (‘-i disk disk.img’), it
has to make many guesses about the metadata. See this file for
details:
https://github.com/libguestfs/libguestfs/blob/master/v2v/input_disk.ml
Sometimes these guesses will be suboptimal, and by supplying the
correct metadata you can get a more correct conversion (‘-i libvirtxml’
or even better getting the true metadata from VirtualBox).
OK, thanks a lot for your helpful feedback, most appreciated.
