Right, and we can use that version, or a newer one and enable rbd as well.

The next question is, is there a difference between the generic rbd and
building against ceph-devel.  (As in, is one ceph only and the other
generic only or can you use both when built against ceph-devel, etc)

Since qemu-kvm-ev enables ceph, if we can also enable ceph in libvirt,
seems like a win to me, if it also does rbd the same as building against
librados2-devel and librbd1-devel.

These may only work with CentOS 7 as well .. have to look at if those
build in CentOS 6.7.

Thoughts?

Thanks,
Johnny Hughes
