Jim I think I understand why I am getting the null pointer exception. The VSManagement service parses the Virtual Systems Setting Data, in the function vssd2xenconfig. When it looks for some property value like so propertyvalue = CMGetProperty(vssd, "OnReboot", status) And that property value does not exist, I am getting an error like this. RequestHandlerIFCXML::doProcess caught Exception:OW_COWIntrusiveReference.cpp: 62 NULLCOWIntrusiveReferenceException: NULL COWReference dereferenced Clearly this shouldn't be happening. Any idea how I can debug this? Raj

Jim Could you shoot over the latest script you are using to create vms? There is this strange null pointer exception I am trying to hunt down. Thanks

Some example python script attached. Very minimal. Would be nice to expand on it and add to repo. Pywbem documentation: http://pywbem.sourceforge.net/documentation.shtml

For DefineSystem, I have a collection of "cimxml conf files'. I've attached example PV and HVM one I'm currently using. Tweak them as necessary and use the fakeclient program I sent invoke DefineSystem on target node.
