I just wonder what will happen if I interrupted the guest via gdb and
then issue "monitor system_reset", also via gdb - common pattern if you
set a breakpoint on some BUG() or fault handler and then want to restart
the guest. Will the guest continue then while gdb thinks it is still
stopped? Likely, we do not differentiate between gdb-initiated stops and
the rest. Could you clarify?
Thanks,
Jan
