Which QEMU version did you use here? Can you still reproduce this

  INT instruction bug in WindowsXP

Status in QEMU:

Bug description:
  This bug is in -no-kvm mode.

  In windowsXP at IDT entry 2&8 is Task gate

  when application use INT 2 or INT 8 it will cause blue screen in XP.

  I found it should cause #GP but not generate hw interrupt.

  also I check this bug with -enable-kvm & my PC and works correctly.
