I had understood that CentOS 7.1 qemu-kvm has RBD support built-in. It was not there on 7.0 but http://tracker.ceph.com/issues/10480 implies it is in 7.1.
You could check on the centos mailing lists to be sure.

Now, what is the best to update for venom vulnerability? Has anyone already recompiled the patched sources and put it in a repository, or the only way is to get the knew sources and recompile again ? In http://vault.centos.org/ les sources don't seen to have been updated yet, where will I find them to recompile if it is the way to go? Thanks a lot!
