this is the patch to check for device model (in XendConfig.py) when the
device_model had no path specified, i.e. XenD was trying to read the
file on the auxbin path. Without this patch applied the meaningless
python error "coercing to Unicode: need string or buffer, NoneType
found" occurred:

TypeError: coercing to Unicode: need string or buffer, NoneType found
This patch raises VmError with message that no valid device model was
specified if None type was found in the device_model specification.
It's been tested on non-existing device model where the message is being
printed. If an invalid (but existing) device_model is set in the
configuration file the domain was destroyed because it crashed. If there
is a path specified (i.e. it's not using auxbin path) it bails with
error that the device model was not found (which was already implemented
there).
