Well, what I don't understand is how many vCPU's are equal to one socket.

Or, to be explicit, let me invent an example: suppose that I have leased 
virtual hardware from some 3rd party, and have obtained a virtual machine with
6 vCPU's. I want to buy RHEL licences to install on that machine. AFAIK, RH 
counts licences in sockets. How many licences should I buy? Or, iow, how many 
sockets is equal to 6 vCPU's?

Does RH have a formula for the number of sockets as a function of the number 
of  vCPU's (and vice versa)?

Best, :-)
