According to the reference 
https://www.ibm.com/developerworks/community/blogs/fe313521-2e95-46f2-817d-44a4f27eba32/entry/enabling_smt_on_powerkvm_guests?lang=en

There are some restrictions to configure SMT what can not be intuitive 
for a Kimchi user.

So I like the idea to keep it only on templates (at least for while) and 
see how Kimchi users react on that.
We will need to properly add a logic to get the best pairs of 
cores/threads according to the vcpus number.

In my mind, we should only add a check box on Template edit: "Enable 
SMT" if checked Kimchi knows what it needs to do when creating a VM
