Questions on setting guest CPU models with ARM kvm enabled

[Jingyi Wang]

Hi all,
    On ARM hardware, as qemu docs describes, "Named CPU models generally
do not work with KVM." May I ask what is the main obstacle to setting a
guest CPU model on later host hardware?

    For example, if I want to start Cortex-A57 guest on Cortex-A72 host,
I noticed that there is not much big difference between these two CPU
models(Please correct me if I'm wrong), what work should I do?


Thanks,
Jingyi
