Hi Josh: Please let me clarify some point. If we want to map an RBD image to a kernel object, it may not ready until kernel 3.8 or 3.9. But if we want to running qemu with RBD, it is ready in kernel 3.6, since QEMU can access it via librbd directly. Do I correct?

Would you mind to estimate when will be available? And which version of kernel? (3.5 or 3.6?)
