libxl__domain_suspend_device_model calls libxl__device_model_version_running,
which may return LIBXL_DEVICE_MODEL_VERSION_QEMU_XEN_TRADITIONAL in case
"dm-version" does not exist.
Is it valid to assume that a non-existant "dm-version" means qemu-trad?
So far I have not tested a PV domU with qemu-trad, not sure if that can work
anyway.

Also, libxl__device_model_version_running may return -1. Is that valid?
