SRU Justification:
Impact: The ceph module is not loadable in a default virtual installation because it depends on the libceph module.
Fix: Add libceph.ko to the appropriate lists (packaging change only).
Testcase: Having the virtual flavour (or meta package) installed only (in Precise a separate flavour still, in Quantal this just does not include the extras package), modprobe for ceph will fail without that change.
