The Red Hat Virtualization Manager creates a limited, internal administration domain during installation. This domain is not the same as an AD or IdM domain, because it exists based on a key in the Red Hat Virtualization PostgreSQL database rather than as a directory service user on a directory server. The internal domain is also different from an external domain because the internal domain will only have one user: the admin@internal user. Taking this approach to initial authentication allows Red Hat Virtualization to be evaluated without requiring a complete, functional directory server, and ensures an administrative account is available to troubleshoot any issues with external directory services.

The admin@internal user is for the initial configuration of an environment. This includes installing and accepting hosts, adding external AD or IdM authentication domains, and delegating permissions to users from external domains.
