60 KVM acceleration in Linux Power hosts is provided by the kvm-hv and
61 kvm-pr modules. kvm-hv is adherent to PAPR and it's not compliant with
62 powernv. kvm-pr in theory could be used as a valid accel option but
63 this isn't supported by kvm-pr at this moment.
67 KVM is not supported. This can be revisited in the future if kvm-pr (or
