https://bugzilla.kernel.org/show_bug.cgi?id=65561 --- Comment #21 from Jatin Kumar <jatin.iitdelhi@xxxxxxxxx> --- The way I would approach this problem is to first check if there is a VM_EXIT while executing this instruction. You should be able to find that in vmx_vcpu_run() function (I guess in KVM code). Put a printk there and print the instruction as well which caused VM_EXIT. Futher you should try to investigate if the control flow is trying to emulate this instruction and then your printk's should be triggered. CAUTION: I haven't spent much time digging KVM code, but I am confident about the VM_EXIT part. Still after putting in some effort, you may want to wait for Paolo's reply :) -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
