Hi Philippe, not sure if it fits in this series, but also the experience of a user running on a machine with cortex-a72, choosing that very same cpu with -cpu and then getting: qemu-system-aarch64: kvm_init_vcpu: kvm_arch_init_vcpu failed (0): Invalid argument is not super-friendly. Maybe some suggestion to use -cpu host with KVM could be good?
