Probably it would be nicer to call them vmcb_{set,clr,is}_intercept and make them take a struct vmcb_control_area*, but apart from that the concept is fine Once we do the vmcb01/vmcb02/vmcb12 work, there will not be anymore &svm->nested.ctl (replaced by &svm->nested.vmcb12->ctl) and we will be able to change them to take a struct vmcb*. Then is_intercept would for example be simply: return vmcb_is_intercept(svm->vmcb, nr); as expected. Paolo
