Several hypervisors need MSR auto load/restore feature. We read MSRs from VM-entry MSR load area which specified by L1, and load them via kvm_set_msr in the nested entry. When nested exit occurs, we get MSRs via kvm_get_msr, writing them to L1`s MSR store area. After this, we read MSRs from VM-exit MSR load area, and load them via kvm_set_msr.
