Ever since Vmware launched ESXi 5.0. It has been difficult to locate their free version of ESXi 4.x license key. Here’s a link I found on forum somewhere. Get it while the link is still active.
- Visit the site https://www.vmware.com/tryvmware/p/activate.php?p=free-esxi&lp=1
- Click “License & download” and login with your vmware user account or register yourself a new one.
- Under “Option 2 : Download ESXi” you will find the VMware vSphere Hypervisor 4.x License.
Please see the following post if you came to find the license key for VMWare ESXi 5.1
