I wouldn't be surprised if: - this v6.6 kernel doesn't hide the MPAM feature as it should (and that's proably something we should backport) - you get a nastygram in the host log telling you that the guest has executed something it shouldn't (you'll get the encoding of the instruction) Can you confirm these two things?
