This was fixed upstream:<br>
<br>
<a href="https://github.com/libguestfs/libguestfs/commit/7291b226d1b08c762ae2f2715a2ac9ed7b8d5d14" rel="noreferrer" target="_blank">https://github.com/libguestfs/libguestfs/commit/7291b226d1b08c762ae2f2715a2ac9ed7b8d5d14</a><br>
<br>
With a more recent virt-v2v it will work fine, as in this example:<br>
<br>
$ virt-builder fedora-22<br>
<br>
$ guestfish --ro -a fedora-22.img -i find /lib/modules | grep xz | head<br>
