To be clear, "-cpu host" for TCG is not talking about the actual
host OS feature support, right ? x86_64 TCG can be run on a ppc host,
so presumably "-cpu host" just means "all features that this TCG binary
is able to emulate" ?

This feels like it is introducing scope for confusion vs KVM -cpu host,
so I wonder if different naming is better for this.

Daniel
