Here's another thread that you might find useful: http://edk2-devel.narkive.com/6BRVus92/qestion-about-how-to-debug-ovmf-on-qemu Occasionally I do use gdb with QEMU, but the solution I use is not suitable for debugging modules in the SEC and PEI phases, only in DXE. I have some terribly rough patches in my local tree that are based on <https://github.com/andreiw/andreiw-wip/tree/master/uefi/DebugPkg>. I don't recall having any luck with SOURCE_DEBUG_ENABLE and the UDK debugger <https://firmware.intel.com/develop/intel-uefi-tools-and-utilities/intel-uefi-development-kit-debugger-tool>, but admittedly it's been a while (= years?) since I last tried to connect debugger VM with debugge VM over a virtual serial port. Others have more recently confirmed it works for them. I think Mike uses it successfully, from a Windows debugger machine maybe?
