环境情况：
Cloudstack 4.1.1, Ceph 0.6.1.7, Qemu 0.12.1.2-2.355 with RBD enable
I have added ceph RBD as primary successfully with ubuntu 12.04 kvm.
but fail on centos 6.4 kvm host in cloudstack.
以下是在centos kvm host上的部分测试，可以通过rbd访问ceph
[root@centos-kvm01 ~]# qemu-img -v | grep rbd
Supported formats: raw cow qcow vdi vmdk cloop dmg bochs vpc vvfat
