Re: [Qemu-devel] Help compiling QEMU with RBD support

[Christian Brunner <chb@muc.de>]

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 solve your
problem.
