A couple of days ago I stumbled upon the following error message while activating Fault Tolerance on a particular virtual machine:

Replay is unavailable for the current configuration.

First I wasted time by verifying the following topics:

  • checking the VM configuration (vCPUs, OS support, disk provisioning,...)
  • tested using dvSwitches instead of vSwitches
  • researching syslogs and the internet

The solution was quite simple: the virtual machine was turned on and therefore Fault Tolerance was not able to work. After shutting down the VM I was able to enable Fault Tolerance and boot the system again.
