    event injection problem

    77y77y77y

      I try to intecept software interruption.  The codes for the event injection are as follows:   

      -----------------------------------------------------------------------

      vm->vmcb->eventinj.fields.vector = vector;  //vector=0x80
      vm->vmcb->eventinj.fields.type = EVENT_TYPE_SWINT;
      vm->vmcb->eventinj.fields.ev = 0;
      vm->vmcb->eventinj.fields.v = 1;

      vm->vmcb->rip += 2;

      ------------------------------------------------------------------------

      It works for all the software interruptions except the system calls (int 0x80)

      For 'int 0x80', after VMRUN, the VM did not continue to finish the system call but directly move to the next instruction of 'int 0x80' .

      Why? Any one can help me?
