Thanks for sharing this, we sorely need testing for NV. I haven't looked at these patches thoroughly but I have some overall feedback. What I'd like to see is that we force *all* KVM selftests to run in VHE EL2 without an opt-in/opt-out. The user had to boot their kernel with kvm-arm.mode=nested, so imposing NV testing on them feels reasonable. Thanks, Oliver
