   The deployment creates the Manager virtual machine, starts the ovirt-engine and high availability services, and connects the host and shared storage domain to the Manager virtual machine.
   When the hosted-engine deployment completes successfully, the Red Hat Virtualization Manager is configured and running on your host. The Manager has already configured the data center, cluster, host, the Manager virtual machine, and a shared storage domain dedicated to the Manager virtual machine.

   Important

   Log in as the admin@internal user to continue configuring the Manager and add further resources. You must create another data domain for the data center to be initialized to host regular virtual machine data, and for the Manager virtual machine to be visible. See Storage in the Administration Guide for different storage options and on how to add a data storage domain.
   Link your Red Hat Virtualization Manager to a directory server so you can add additional users to the environment. Red Hat Virtualization supports many directory server types; for example, Red Hat Directory Server (RHDS), Red Hat Identity Management (IdM), Active Directory, and many other types. Add a directory server to your environment using the ovirt-engine-extension-aaa-ldap-setup interactive setup script. For more information, see Configuring an External LDAP Provider in the Administration Guide.
   The answers you gave during configuration are saved to a file to help with disaster recovery. If a destination is not specified using the --generate-answer=<file> argument, the answer file is generated at /etc/ovirt-hosted-engine/answers.conf.

8. Subscribing to the Required Entitlements

   Subscribe the Manager virtual machine to the required entitlements. See Subscribing to the Required Entitlements in the Installation Guide for more information.
