Hi,

Have you buill it by sources ?

I did the same thing, build the RPMs and now show rbd support, however when I try to start an image I get:

Hi,
Centos 7 qemu out of the box does not support rbd.

I had to build package with rbd support manually with "%define rhev 1" in qemu-kvm spec file. I also had to salvage some files from src.rpm file which were missing from centos git.
