FWIW Debian had a similar bug, fixed by updated qemu to a newer version. See: http://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1056306.html If that doesn't work, try looking at what qemu is actually doing. You could try attaching gdb to the guest, as described here: http://libguestfs.org/guestfs-performance.1.html#detailed-debugging-using-gdb
The Debian fix was to upgrade to qemu-kvm 1.1.1 but in this case the user's issue is happening with qemu-kvm 1.1.1. Its possible Debian is carrying a different patchset then Gentoo is as our patchset matches better with what Fedora carries but I'll have to check what differs. That being said, the best way forward right now is to do exactly what Richard suggested in comment #1 and attach the results.
ping REdOG: Any chance you can provide the feedback requested?
I'm bump and maksbotan commited new version libguestfs. REdOG, pleas confirm or not this bug in new version
