This is a bug in qemu 0.15, fixed in qemu 1.0 (although 1.0 introduced
another bug which prevents libguestfs from working out of the box
there too).
If you recompile libguestfs from source then it will detect this qemu
problem at ./configure time and add some code to work around it.
However the binaries on the website weren't compiled this way.
In Fedora we patch around many qemu bugs, so it's worth keeping an eye
on our qemu packages:

Here is the patch you need to qemu 0.15 which fixes the above bug:
