I don't know how serious this is. It *is* reproducible easily however:
$ virt-builder rhel-7.0
$ virt-v2v -i disk rhel-7.0.img -o null
[ 0.0] Opening the source -i disk rhel-7.0.img
[ 0.0] Creating an overlay to protect the source from being modified
[ 0.0] Opening the overlay
[ 8.0] Initializing the target -o null

I think this was a bug in old virt-v2v. Yay! The fix is: https://github.com/libguestfs/libguestfs/commit/035f47cdde4052e77613c77d2e5e0f24dbab082f Tested the bug with: libguestfs-1.27.49-1.1.el7.x86_64 virt-v2v-1.27.49-1.1.el7.x86_64 Use virt-v2v to convert a rhel7 guest,there is no such warning info shows,so move the bug to VERIFIED.
