The main problem is that the original poster's kernel doesn't boot on
top of qemu. I can't see from the logs what kernel they are trying to
use, but that's going to be a problem.
Strongly suggest:
(a) Switch to libguestfs from git, since the version you are using is
8 months old, and I completely changed how DTBs are handled in the
latest version.
(b) Don't run stuff as root.
(c) With the version from git, do:
./configure
rm -rf tmp/.guestfs-*
make clean
make
make quickcheck
and let us see the complete log of that.
