Hi, Prasanna I did not make any customizations to the procedure.You only need to put the source code in the right path when building Ceph. The errors I mentioned above occur because qemu is looking for the Ceph libraries and not finding them.The library is ceph-devel.x86_64. So I think for those users who don't want to build Ceph can just install ceph-devel rpm packages(yum install ceph-devel.x86_64).
