Ms SQL Server 2019 Enterprise Edition

Hi Teams,

I'm need to sizing and planning for install the Ms SQL Server 2019 Enterprise on virtualization. I have download and read the guide but still can't understand the term for SQL EE version run on virtualization. 

Here our virtualization infra.

1. VMware vSphere Host (ESXi) server spec:-

One Node Server = 2 Processor socket / 8cores each

2. Plan to install one VM server and run SQL 2019 EE.

VM (SQL) spec = 4vcpu

Question:

1) How we can calculate the licensing of SQL Server 2019 EE on virtualization? It's based on ESXi host spec? or virtual machine (vm) spec?
