Sorry! for the late reply and thanks a lot for responding.
Yes, I have enabled "-DDEBUG_ON_SERIAL_PORT=TRUE" but thanks for letting
me know, I will use the debug.log method.

Sure, I actually tried those and they work :) The issue, I think is
related to my specific dev machine setup (which runs Ubuntu 15.04).
Because, on two different machines running Ubuntu 16.04, I was able to
build and boot OVMF successfully on qemu (both x86-64 and 32-bit) and
the same image boots on my dev machine as well. I see the problem *only*
when OVMF is built on my dev machine. So, I will try to figure it out.
But, thanks a lot for the suggestions :)
