A vRealize Automation IaaS DEM Worker that communicates with and collects data from Red Hat Enterprise Virtualization (RHEV) must meet additional requirements, in addition to those for all IaaS Windows servers and DEMs in general.
You must join each RHEV environment to the domain containing the DEM Worker server.
The credentials used to manage the endpoint representing an RHEV environment must have administrator privileges on the RHEV environment. When you use RHEV for provisioning, the DEM Worker communicates with and collects data from that account.
The credentials must also have enough privileges to create objects on the hosts within the environment.
