Can you clarify?

This article is good reading material for this:

It's still over allocation since you have more logical cores than 
physical, but it is weird that the database reports something different 
than the UI.
Eli, when hyper-threading is enabled, how is that saved in the database, 
does the UI display vale change, but the database values stay the same?

H Alexandr,

The vCores are the logical cpu cores,
and if you has more vCores than Host Cores it means that you have over 
allocation for the hosts.
So, if on a specific vm one of the cores will be on 100% usage than all the vms 
using this core will show 100% as well.

Hello,
why we have in reports host cores but not logical cpu cores? For example
in Cluster Capacity Vs. Usage report I always have more vCores then
Host Cores.
Thank you.
