--- Comment #23 from Jidong Xiao <jidong.x...@gmail.com> --- Jatin, do you mean that if one instruction triggers a VM_EXIT, then it won't trigger the emulate code? So why the emulate code tries to emulate those privileged instructions, like wrmsr, rdmsr, mov cr to reg, mov dr to reg, I think these instructions will trigger VM_EXIT anyway, but we see the kvm emulator still attempt to emulate them. (In reply to Jatin Kumar from comment #21) > The way I would approach this problem is to first check if there is a > VM_EXIT while executing this instruction.
