My code (arch/x86/x86_emulate/x86_emulate.c) does have a case label for it: 3677 case 0xfa: /* cli */ 3678 generate_exception_if(!mode_iopl(), EXC_GP, 0); 3679 _regs.eflags &= ~EFLG_IF; 3680 break; Maybe the IOPL test fails there? Tamas, does your guest die after a CLI as well? Thanks, Razvan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
