Let's instead add: - KVM_CAP_MSR_EXITS - KVM_CAP_ENABLE_MSR_EXIT - KVM_CAP_DISABLE_MSR_EXIT and 3 kinds of exits: KVM_EXIT_MSR_READ, KVM_EXIT_MSR_WRITE, KVM_EXIT_MSR_AFTER_WRITE. The first two use four fields (type, msr, data, handled) and #GP if handled=0 is zero on the next entry. The last one uses the first three fields and can be used for HyperV.
