I have been looking into registering some domain events though the

be due to lack of event support in Xen. This is the error I am getting:

The Xen driver does support events. I think this is probably a misleading
error message which in fact is trying to tell you that you need to provide
an event loop first.
Take a look at examples/domain-events/events-py.py for a good example
of how to use events. I've not tested it with Xen recently, but it ought
to work
