I examined the xentrace facility and copied the code to mmap pages. My mmap fails, and upon trying out the xentrace program, I found that it fails in exactly the same way, ie, returns errno 11, "Resource Temporarily Unavailable". I have allocated my memory buffers just like common/trace.c does it, etc. Is this trace stuff not working anymore, did it ever work, and/or what is the recommended way to do what I want?
