An administrator is attempting to enable Legacy Fault Tolerance (FT) on a virtual machine and observes the following in the vSphere Web Client: Fault Tolerance has not been licensed on host <hostname>

vSphere Standard is the minimum license tier that includes Legacy Fault Tolerance, which uses vLockstep technology and is limited to VMs with a single vCPU. Because Legacy FT is bundled at the Standard level, no higher edition is needed to enable it on a qualifying VM.

Enterprise includes Legacy FT but is above the minimum - Standard already provides this capability, so Enterprise cannot be the minimum.

Enterprise Plus includes all FT variants but is a higher edition than required - Standard already covers Legacy FT licensing.

Essentials Plus is a small-business bundle that does not include any Fault Tolerance feature licensing.
