If we can't find details for the debug exception in our debug state then we can assume the exception is due to debugging inside the guest. To inject the exception into the guest state we re-use the TCG exception code (do_interrupt). However while guest debugging is in effect we currently can't handle the guest using single step as we will keep trapping to back to userspace. GDB makes heavy use of single-step behind the scenes which effectively means the guest's ability to debug itself is disabled while it is being debugged.
