At least for now cpu-topology is implemented only for KVM.

We already say this, but this tries to be more explicit,
and also show it in the examples.

This adds a new reference in the introduction that we can point to,

Thanks for your patch! I'd maybe write "cpu" with capital letters here like it is done in the other spots in this file. I can change that while picking up the patch.
