Hey All
If you had multiple ESXi licenses and not able to use it within vCenter, because your host has 2 or more CPUs – to get it working all you need to do is to combine your licenses into one depending on situation.
You can’t have multiple licenses assign to a host, it can only be assigned per license key per host. If you run into this problem, then all you need to do is to login to https://my.vmware.com/ and then manage licenses. You will have an option to combine multiple into one. Once that is done, you will be provided a new license key.

Enjoy :)
