[Rdo-list] Problem with Cinder (Juno) and Ceph

[Walter Valenti]

I've followed directly the ceph documentation.
Reading the RDO documentation, at point 4 of
"Install Virtualization for Ceph Block Devices" tells:
Older releases of RHEL and CentOS don't provide the rbd format required for use with Ceph.
Now, I think: Centos7 isn't a older release.
But the execution of "qemu-img -f", give me:
vvfat vpc vmdk vhdx vdi sheepdog sheepdog sheepdog raw host_cdrom host_floppy host_device file qed qcow2 qcow parallels nbd nbd nbd iscsi gluster gluster gluster gluster dmg cow cloop bochs blkverify blkdebug
There isn't "rdb".... Why ????
