Hi List, My question is about VM-Exit& VM-Entry controls for MSRs on Intel's processors. For VM-Exit, a VMM can specify lists of MSRs to be stored and loaded on VM exits. But for VM-Entry, a VMM can only specify a list of MSRs to be loaded on VM entries. Why does not the processor have the feature that stores MSRs before loading new ones for VM entries?
Presumably the host knows what values are in those MSRs, so it doesn't need to store them.
