Server2016 Essentials cannot add RDS Virtualization Host

I get either this error in the quick start deployment:

Failed:
Unable to install the role services. ArgumentNotValid: The role, role service, or feature name is not valid: 'rds-virtualization'. The name was not found.

Or

Failed:
Unable to install RD Virtualization Host role service on server DC-BOZ-01.BOZIEDOIL.local ArgumentNotValid: The role, role service, or feature name is not valid: 'rds-virtualization'. The name was not found.
Unable to install RD Virtualization Host role service on server DC-BOZ-01.BOZIEDOIL.local Exception of type 'System.Exception' was thrown.

All other RDS services including licensing are working and licenses installed. Hyper-V is installed and basic VM configured ok. Just cannot get a Virtualization Host configured to get users to it.

Ooo, yikes. everything else in RDS was working now it is blank.

Help!
