Does anyone know what happened to kemari?
Back in March it was on the list for a possible merge in qemu 0.15. In
April the last update was sent to this list. After that everything
remained silent.
I think it's a really interesting project and I wonder why it isn't picked up.
Thanks,
Christian

Hi Dyweni,
are you sure that you have installed ceph (especially librados and the
header files)?
Josh's patches use the newer librbd from ceph 0.27. With this library
the qemu driver gets a lot simpler and avoids code duplication in ceph
and qemu. - It's the future, but I don't think it will
I almost forgot: If you are already using ceph 0.27, then you will
need the pathes. Configure is checking for a function that isn't

you resend the patch.
