Hi,

This series aims to improve user experience by providing
a better error message when the user tries to enable KVM
on machines not supporting it.

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?

I agree this should be improved, but it is out of the scope of this
series :)
