However, I want to test the new features but cannot find a fully compatible Kernel for CentOS 7.

What do you mean by "can't do" - no output at all? Something similar was reported here [1]. What's the output of "rados -p <your rbd pool> stat rbd_directory"? > 'rbd mount' does not work with the stock 3.10 kernel, but works with the 4.6 kernel. Anything in dmesg on 3.10?
