You might use this preview one : http://people.redhat.com/~rjones/libguestfs-RHEL-7.2-preview/libvirt-1.2.17-3.el7.src.rpm I personally rebuild libvirt from last official releases which enable ceph by default for el7 : http://libvirt.org/sources/ My dogfooding tests still can be found here : https://copr.fedoraproject.org/coprs/jmliger/virt7-upstream/ 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. Maybe I'm wrong but ceph-devel seems to have been replaced by librados2-devel and librbd1-devel in el7. These may only work with CentOS 7 as well .. have to look at if those build in CentOS 6.7. Which ceph release for CentOS 6.7 Hammer or Firefly ? Jean-Marc Liger Thoughts?

Would it be possible to enable RBD support in it?Yes, we should definitely enable RBD / Ceph support in libvirt!I know quite a few cases (in the Cloudstack community) that switched to Ubuntu particularly because CEPH support was missing. The recommendation is to rebuild the rpms, but this is not a viable thing for everyone. E.g. http://blog.widodh.nl/2015/04/rebuilding-libvirt-under-centos-7-1-with-rbd-storage-pool-support/ Another thing that I noticed on the CentOS ml recently is an alleged lack of hooks, https://www.libvirt.org/hooks.html And last but not least, where could I find the libvirt (s)rpms that the SIG produces?
