Cannot add an ESXi host to vCenter Server

Adding an ESXi host to vCenter Server fails

You see the error:

Host cannot be added to the vCenter as there are not enough Virtual Center Agent Licenses

Resolution

If an ESXi host is licensed with the free version of the license key, you cannot add it to vCenter Server. This license does not contain the VirtualCenter Agent, which is necessary to manage a host with vCenter Server. This feature remains locked as long as the host is licensed with the free version of the license key.

To add ESXi hosts to vCenter Server, you must license the ESXi hosts with:

vSphere Essentials

Licensing an ESXi host with vSphere Essentials allows you to manage three ESXi hosts using vCenter Server. For more information on purchasing vSphere Essentials, see VMware vSphere and VMware vCenter Server Pricing.

vSphere Standard, Enterprise, or Enterprise Plus

Licensing the ESXi host with one these products unlocks the add-on features that allow you to manage ESXi hosts using vCenter Server. For more information about these products, see Compare vSphere Editions.

For more information on licensing an ESX/ESXi 4.x host, see Licensing ESX 4.x, ESXi 4.x, and vCenter Server 4.x (1010839).

For more information on licensing an ESXi 5.x host, see Licensing ESXi 5.x and vCenter Server 5.x (2014295).

For more information on licensing an ESXi 6.x host, see Licensing ESXi 6.x and vCenter Server 6.x (2107538).
