totally.  qemu doesn't work 100% like that, but almost:

% qemu -hda disk.img
...
in qemu:  ctrl-alt-2 (switches to qemu console)
qemu> gdbserver

on other console:
% gdb kernel.debug	# the one booted from disk.img
gdb> target remote localhost:1234
gdb> bt

works excellent.  well, interrupts sometimes confuse you debugging (every now and \
then you'll be in fastintr :)

definitely my choice for hardware driver debugging.

cheers
