System requirements
Prior to deploying the FortiAuthenticator-VM virtual appliance, either VMware vSphere Hypervisor (ESX versions 4.0 or 4.1, ESXi versions 4/5/6), Microsoft Hyper-V Server (2010 and 2016), or Virtual Machine Manager for KVM must be installed and configured. Note that, Virtual Machine Manager version 1.3.2 was used for the purposes of this document.
The installation instructions for FortiAuthenticator-VM assume you are familiar with both VM platforms and their related terminology.
