with qemu-kvm-1.5.3-126.el7.x86_64:

libvirt: QEMU Driver error : unsupported configuration: IOThreads not
supported for this QEMU

Ah, my fault for adding iothreads. We could remove them (they don't add more than a small performance improvement, hardly noticeable most likely) 
if it makes deployment harder.

I guess snapshots might be another problem, though never tested it.

though its not really complete.
