[Libguestfs] difficulty using virt-v2v with OVA

I have a Fedora 24 system I can already get this working for most OVA
files, just the BSD and atomic ones weren't recognized. Assuming my
version of virt-v2v is just old, I installed rawhide on a different system
and tried with virt-v2v-1.37.8-1.fc27.x86_64 and now its having another
problem. Is there a known version of virt-v2v I should be using? Here is
the output from the rawhide attempt happens for any OVA file I try:
# virt-v2v -v -x -i ova graylog.ova -o qemu -of qcow2 -os /var/tmp
