This seems to still be a problem. I'll try to get more information about what's going on. It looks like there's an error somewhere:

Retested with qemu 1.5 from the havana cloud archive for ubuntu, and ceph 0.67.4. It worked fine. I'm not sure exactly what fixed it, but I'm guessing it's the newer version of qemu (maybe the async flush).
