It is the problem when the intention is to play in a sandbox with different things.

I don't consider polluting your log a real problem. It is just an annoyance that could be fixed by using "ack -v"

It only tells you the mapping is inexistent. The problem is if in debug build you don't see at all this message (assuming you have kpti enabled). This would mean you would overwrite a random page.
I already have that understanding ;) But curious if XEN 4.12 is going to be released with such the issue remains?

I don't consider it as a critical issue because of the type of guest we currently support, so it is not in my queue for Xen 4.12 fixes.

Feel free to suggest it as a blocker if you think it is.
