Thanks, K.Y.

In terms of the address for the MSR, I suggest that you choose one
from the range between 40000000H - 400000FFH. The SDM (35.1
ARCHITECTURAL MSRS) says "All existing and
future processors will not implement any features using any MSR in
this range." Hyper-V already defines many synthetic MSRs in this
range, and I think it would be reasonable for you to pick one for this
to avoid a conflict?
