If you run 6K/7k over HYP or FND license, then yes, the above link applies to both. Not sure if you can also buy either license with TRC or spec-based TRC, if so, then they also fall under the guidelines from the link.
If you run any of the above options over VMware std, ent, or ent+ license, general co-res guidelines from virtualization wiki apply.
