 FWIW, I'm using qemu-dm (i.e. traditional) in 4.3 and am successfully
 passing USB, audio, GPU PCI devices using it (as long as I stay under
 the 2GB domU RAM limit). So whatever the issue is it isn't generic.

 That bug report doesn't include the domU config file, and IIRC
 I saw a similar error when device_model/device_model_override and
 device_model_version don't match or are unavailable in the build
 (e.g. building without upstream and specifying traditional or
 vice versa). More info needed to verify, I think.
