Hi Anupam & Valdis, I don't disable CONFIG_MODULE_SIG configuration in kernel. Since from this post (http://stackoverflow.com/questions/24975377/kvm-module-verification-failed-signature-and-or-required-key-missing-taintin), the answer said only disable this option in module's Makefile is enough. So Is this answer wrong? That is what I am confused. Thanks!
