So I think what you're saying is you want it to somehow support using
'kvm_exit' for PR and 'kvm_userspace_exit' for HV?

Or actually use 'kvm_exit' if it exists and fall back to 'kvm_userspace_exit',
so that if HV starts providing 'kvm_exit' the script will pick that up without
further changes.

cheers
