Hi, Thank you for your help!
I'm modifying the source code of xen-4.4.1,I hope throurh printing debug information to track the execution order of functions and check the value of some variables. This is my ultimate goal. But I don't know how to do it in the python code. I tried to print debug information into files,but I couldn't find the file I created.
