Summary:

1) xentrace -e all trace.out (this command will record all the events)

2) cat trace.out| xentrace_format formats | more

xentrace_format is a program to translate the binary format of trace.out to text format.

The formats file is in /tools/xentrace/formats. In the same directory, there is a file called xentrace_format. It is not the "format" file, it is a python program. If you use it as format file, you will get an error "SyntaxError: Unexpected EOF while parsing".
