I don't want to move the actual exit-code itself into generic code. This code is different between svm and vmx. I think we could implement a call-back in kvm_x86_ops which is called when a vmexit is requested. The benefit is that we have a single and well-defined place where we emulate a vmexit. SVM already as a similar mechanism internally because nested_svm_vmexit may sleep and can't be called from certain places. Another reason is that emulating a vmexit at a wrong plase may have side-effects (for example when called from within the instruction emulator). With a generic request-bit I can remove the SVM internal implementation and nested vmx could use it too. I am certain you will need something similar in nested-vmx too. > Do you want to move some of the exit logic to x86.c - e.g., for the > injection logic? Thats another and probably more complex topic. I need a better understanding of (nested-)vmx before we discuss how this can be done. But a vmexit-callback may be helpful there as well.
