Well, xen and bochs do not push an error code for real mode #GP. I

Jun, perhaps you can clarify? do #GP exceptions in real-mode push an
error code?
Avi,
Exceptions in real-mode do not push an error code in the stack.
Thanks. You might consider updating the documentation, for example #DF
states that an error code of 0 is always pushed.
In vm86 mode #GP exceptions push an error code, triggering a protected-mode
handler in the monitor, as you know. Is it possible that the guest is actually
using vm86 mode?
No, it's a real mode guest. It's emulated using vm86, of course, but it
thinks it's in real mode. The question was, when we inject a #GP, #SS,
or #DF exception, should we also inject an error code, and according to
your clarification, the answer is no.
