What annoys me about hap and hvm is that it comes from a
paravirtualization viewpoint, where pv is the default model, and
hardware extensions are an optional addition. With kvm it's the other
way round: the base model is full virtualization, and paravirtualization
is an optional add-on. I'd rather call traditional shadow paging
"software-assisted paging".
