Dear iKGT Designer： I’m writing to debug ikgt when ikgt executes in vmx-root ring 0(ring -1) below the kernel. I've tried to debug ikgt following the steps in the topic "ikgt debug mode". But there is only Linux kernel messages(ring 0) not the messages in ring -1(below the kernel ) . Is it my mistake in debugging? Or there is another way to debug? I am looking forward to your kindly reply. Thanks! Steven Song Renmin University of China
