That's your error according to libvirt.  qemu in this case will be
trying to allocate ~ 500 MB of RAM (using ordinary malloc).

Do you have enough free memory on the host?

Another thing to do would be to look for the file called
guestfs-ecwkqdns6qyvh9v5.log (probably located somewhere under
/var/log/libvirt/qemu), and see if there is some other qemu error
which libvirt is hiding from us.

You could also remove libvirt from the equation and have libguestfs
run qemu directly, to see if that makes any difference and/or allows
you to see the real error:

  LIBGUESTFS_BACKEND=direct libguestfs-test-tool

More information possibly in this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=765733

BTW you don't need to run libguestfs-test-tool as root.

Rich.
