Adding the test to x86/realmode.c will be much easier.

Yes, that should be the point. x86/realmode.c is always running in
emulation mode. I added the testing here there but no error occurred.
I cannot find the reason.
The code is as follows added to x86/realmode.c
static void test_nopl(void)
{
MK_INSN(nopl, .byte 0x0f, 0x1f, 0x00\n\r);

Yes, I load kvm-intel with unrestricted_guest=0 and the emulator runs
well. I will give another test case in x86/realmode.c later.
BTW, what is the action when a 64-bit instruction executes in
x86/realmode.c? Should I add 64-bit insn tests only in x86/emulator.c?

The test fails for me on CPU without unrestricted guest support. This
means you either test
I mean after adding unrestricted_guest=0, the error is reproduced.
Sorry for confused expression. I have committed another patch in
x86/realmode.c.

Ah, OK. unrestricted_guest=0 works then :)
