If that's correct then starting from there and building a new RPM

I guess there are two ways to approach this.
1. use the existing ceph source rpm here.
http://ceph.com/packages/ceph-extras/rpm/centos6/SRPMS/qemu-kvm-0.12.1.2-2.415.el6.3ceph.src.rpm

What I've been doing in my cluster is pickup the RHEV (version 6 or 7 as
needed) qemu source RPM and use them. It is quite simple really:
- install & configure rpmbuild. There are numerous howtos for this.
- fetch and install qemu source rpm from RHEV. Google around and grab
latest version. eg. for CentOS 7 (RHEV 7 based) I found them here:
http://springdale.math.ias.edu/data/RedHat/enterprise/7Server/en/RHEV/SRPMS/qemu-kvm-rhev-2.1.2-23.el7_1.3.src.rpm
- rpmbuild -ba the spec file, it will probably complain about missing
development packages. Satisfy them
- rpmbuild again, wait, grab the resulting binary rpms from the
RPMS/<arch> folder and distribute them as needed.
On occasion, you may need to tweak the spec file a bit. For example, the
above RHEV 7 srpm required librbd1-devel and librados-devel which have
been consolidated in ceph-devel. Just commenting out the requirement and
having ceph-devel installed allowed the build to proceed. But these
fixes are trivial.
