vdsm does not require librbd since qemu brings this dependency, and vdsm does not access ceph directly yet.
Maybe qemu should require newer version of librbd?
Upstream QEMU builds against any librbd version that exports the necessary APIs.
The choice of library versions is mostly up to distro package maintainers.
Have you filed a bug against Ceph on the distro you are using?
Thanks for clearing this up Stefan. Bernhard, can you give more info about your Linux version and installed packages (.e.g qemu-*)? Nir

On the monitor hosts I see traffic with the ceph-mon-port, but not on other ports (the osds for example). In the ceph logs however I don't really see what happens. Do you have some tips how to debug this problem?
