Laszlo, I works really well for me using QEMU on Windows.
* Build OVMF setting -D SOURCE_DEBUG_ENABLE and -D DEBUG_ON_SERIAL_PORT. * Configure The UDK Debugger SoftDebugger.ini file to use TCP port 20716 [Debug Port] Channel = TCP Server = localhost Port = 20716 * Configure QEMU so the monitor and serial port are redirected to a tcp ports 20717 and 20716. -monitor tcp:localhost:20717,server -serial tcp:localhost:20716,server I use a batch file to launch the UDK debugger and and terminal emulators immediately before running QEMU because the tcp server in QEMU will timeout of a connect does not happen quickly. start "Monitor" /B "c:\Program Files (x86)\teraterm\ttermpro.exe" localhost:20717 /nossh start "Debugger" /B "C:\Program Files (x86)\Intel\Intel(R) UEFI Development Kit Debugger Tool\eXdi.exe" /LaunchWinDbg start "Console" /B "c:\Program Files (x86)\teraterm\ttermpro.exe" localhost:20715 /nossh start "QEMU" /B "%QEMU_PATH%\qemu-system-i386w.exe" ^ -machine q35,smm=on,accel=tcg -cpu Nehalem ^ -global ICH9-LPC.disable_s3=1 ^ -drive if=pflash,format=raw,unit=0,file=%EDKII_BUILD_OUTPUT%\FV\OVMF_CODE.fd,readonly=on ^ -drive if=pflash,format=raw,unit=1,file=%EDKII_BUILD_OUTPUT%\FV\OVMF_VARS.fd ^ -monitor tcp:localhost:20717,server ^ -serial tcp:localhost:20716,server Since the serial connections are redirected to tcp ports on the localhost, this actually provide an excellent UDK Debugger experience.
