Thanks for your reply.
This method maybe only can print some log to serial. Is there any way to
control ovmf work flow like step by step debug?

Subject: Re: [edk2] Qestion about how to debug OVMF on QEMU
in summary
1. Change the gEfiMdePkgTokenSpaceGuid.PcdDebugPrintErrorLevel = 0xFFFFFFFF
2. run build -D -D DEBUG_ON_SERIAL_PORT
3. install com2com ( to create virtual COM ports on your laptop in case you
dont have )
4. qemu-system-x86_64.exe -bios OVMF.fd -serial COM1
