How do you know that reset was done here? This is not the only place
where qemu_system_reset_request() is called.

Are you asking what is triple fault or why it happened in your case?
For the former see here: http://en.wikipedia.org/wiki/Triple_fault
For the later it is to late to tell after VM reset. You can run QEMU with
-no-reboot -no-shutdown. VM will pause instead of rebooting and then you
can examine what is going on.
