You licensed the My vCenter Server 5.1 system. To complete the licensing configuration of your vSphere environment, you must assign the vSphere 5.x Standard license key to the ESXi-A and ESXi-B hosts before their 60-day evaluation period expires.

You are using the ESXi-A and ESXi-B hosts in evaluation mode and have configured vMotion. When the evaluation period of ESXi hosts expires, the hosts disconnect from vCenter Server. Powered-on virtual machines continue to run but you cannot power on any new virtual machines. You cannot use vMotion on ESXi hosts when they are disconnected from vCenter Server.

Licensing information about the host appears.

The ESXi-A and ESXi-B hosts are in licensed mode. You completed the licensing configuration of your vSphere environment.

The scenario assumes that the ESXi-A and ESXi-B hosts have 2 CPUs each. The CPU usage for the vSphere 5 Standard license is 4 CPUs.

Use the license reporting function in vCenter Server to view the license usage for vSphere 5 Standard.

In a production environment, viewing the license usage for vSphere products regularly can help you to estimate the current and the future licensing needs of your vSphere environment.
