Virtual Appliance Pre-Boot Authentication

A system for pre-boot authentication of a virtual appliance includes one or more subsystems to receive a command to power-on an information handling system (IHS). After receiving the command to power-on the IHS, the system initializes a power-on self test (POST), passes control of the IHS to a hypervisor, loads a concurrent service environment (CSE), requests user credentials, receives user credentials, authenticates user credentials using the CSE and authorizes a specific operating system image from a plurality of images to run on the IHS via the virtual appliance after the user credentials are authenticated.
