[Nitin>] Avi, Would you like to elaborate more on these three mode's usage scenario? As I see, there are 2 things to look for while providing the cpuid to the guest. 1. Guest migration across different hosts. This limits exposed cpu features. 2. Utilizing host CPU features. This expands exposed cpu features. Both these needs should be accommodated keeping the flexibility to override.
