Yes and no. I am using a self-built 4.3.0 rpm based fairly closely on the CRC 4.2.x rpms for EL6. This includes a patch to only build qemu-dm and make it the default, which, presumably, means that I don't have to explicitly specify device_model_version. But maybe I'm wrong. I'll try specifying it explicitly and see if that helps. Gordan
