Chapter 5. Adding Hosts
To provision a Red Hat Enterprise Linux OpenStack Platform environment, you must add hosts to the installer to act as nodes in that environment. Adding a host to the installer allows you to manage the host via the user interface, from collecting details on the hardware, operating system, and current status of the host to assigning that host to a role in a Red Hat Enterprise Linux OpenStack Platform environment and installing the base operating system and services required for the host to act as a node in that environment.
5.1. Host Status Types
Each host in the user interface is assigned a status type in accordance with the most recent action performed on or upcoming changes to be applied to that host. The following table outlines the status types to which hosts can be assigned. You can view the status of a host at any time by clicking → in the main title bar of the user interface.
Table 5.1. Host Status Types

| Disabled | Alerts have been disabled for the host. The installer continues to collect reports from the host, but does not report the current status of the host. |
| Build | The host has been added to the user interface, but has not been provisioned. |
