<div dir="ltr">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 --qemu-boot libguestfs: trace: set_verbose true
