xentrace returns error

Man Chon Kuok
Hi,

I want to use xentrace to look at some debugging messages, but when I called xentrace, I received the following message:

mkuok@mkuok-linux:~$ sudo xentrace trace
ERROR: Failed to map cpu buffer! (13 = Permission denied)

Any guidance on xentrace is appreciated.
