Execute commands directly on the machine:

Qemu-img info rbd:nova/21d85da5-4844-418a-9fa8-486e8e6d0800_disk

Then execute the qemu-img:

No support for rbd was found.

Then execute:

/ usr/local/qemu/bin/qemu-img

This means that you can compile and upgrade the qemu-img with rbd by yourself. It is not used, and the system comes with it.

Back up the original, cp to the system default location:

Mv / usr/bin/qemu-img / usr/bin/qemu-img.bak

Cp / usr/local/qemu/bin/qemu-img / usr/bin/

Try again:

Success.
