It's my pleasure to receive your reply and get your advice.

Actually I really want to debug source codes from the OS boot(from 
systemd first starts) with virtual machines just like debug kernel 
sources or in some other ways I don't know .

And I also do some works but failed, so I ask for your help.

Thanks very much!
