Are you trying this on an UP or SMP guest? I do see single step mem_events after. I've tried it on a SMP HVM Slackware guest. What behaviour am I observing? The gla and gfn values are being printed out - but I don't know how to detect a write operation based on them. Tim Deegan has kindly suggested that I pass those values to a debugger API that I assume Xen has, but I don't think there have been any replies on that topic since. Unfortunately I don't have access to the computer I've written the test code on, and it's a rather complicated setup that I can't easily duplicate at home, so if you need specific details (gfn/gla values, etc.) I'm afraid I'll only be able to provide them on Monday.
