Explanation:
ESX and vCenter Server Installation Guide, ESX 4.0, vCenter Server 4.0, page 108. ‘License keys have a certain amount of capacity. Capacity is based on the number of processors in the host or the number of instances of the software asset. Dual-core and quad-core processors, such as Intel processors that combine two or four independent CPUs on a single chip, count as one processor.’
Therefore since there will be 4 CPUs in total, 4 licenses are required.
