It does sound odd. Yes, Intel and AMD have differences around CMCI ... but we are never going to send a CMCI to a guest (there is no point, it can't do anything useful with the information, it may do something pointlessly stupid like stop using a guest physical page). The only reason I suggested making MCG_CAP pretend that CMCI was supported was a small optimization ... if a Linux guest sees that CMCI is supported, it will not poll the machine check banks looking for corrected errors.
