The Manager has already configured the data center, cluster, hypervisor host, the Manager virtual machine, and a shared storage domain dedicated to the Manager virtual machine. 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 Enterprise Virtualization Manager to a directory server so you can add additional users to the environment. Red Hat Enterprise 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 ovirt-hosted-engine-setup script also saves the answers you gave during configuration to a file, to help with disaster recovery.

Red Hat Enterprise Virtualization 3.6Installing and Maintaining the Red Hat Enterprise Virtualization Self-Hosted EngineAbstract A comprehensive guide to the self-hosted engine. Chapter 1. Introduction A self-hosted engine is a virtualized environment in which the engine, or Manager, runs on a virtual machine on the hosts managed by that engine. The virtual machine is created as part of the host configuration, and the Manager is installed and configured in parallel to the host configuration process. The primary benefit of the self-hosted engine is that it requires less hardware to deploy an instance of Red Hat Enterprise Virtualization as the Manager runs as a virtual machine, not on physical hardware. Additionally, the Manager is configured to be highly available. If the host running the Manager virtual machine goes into maintenance mode, or fails unexpectedly, the virtual machine will be migrated automatically to another host in the environment. A minimum of two self-hosted engine hosts are required to support the high availability feature. Table 1.1. Supported OS versions to Deploy Self-Hosted Engine System Type Supported Versions Red Hat Enterprise Linux Host 7.2 Red Hat Enterprise Virtualization Hypervisor Host 7.2 HostedEngine-VM (Manager) 6.7 It is important to synchronize the system clocks of the hosts, Manager, and other servers in the environment to avoid potential timing or authentication issues. To do this, configure the Network Time Protocol (NTP) on each system to synchronize with the same NTP server. 1.1. Installation OptionsSelf-Hosted Engine Hosts You can use Red Hat Enterprise Virtualization Hypervisors or Red Hat Enterprise Linux hosts, or both. Red Hat Enterprise Virtualization Hypervisor is distributed as an ISO file and contains only the packages required for the machine to act as a virtualization host. See Chapter 2, Deploying Self-Hosted Engine on Red Hat Enterprise Virtualization Hypervisor Red Hat Enterprise Linux systems subscribed to the appropriate entitlements can be used as virtualization hosts. See Chapter 3, Deploying Self-Hosted Engine on a Red Hat Enterprise Linux Host. Self-Hosted Engine Manager You can use the RHEV-M Virtual Appliance, or you can install and configure the Manager virtual machine manually. The RHEV-M Virtual Appliance automates the process of installing and configuring the Manager virtual machine, and does not require you to access the virtual machine during the setup. Manually installing and configuring the Manager virtual machine is also supported but requires you to access the virtual machine directly during the setup. Chapter 2. Deploying Self-Hosted Engine on Red Hat Enterprise Virtualization Hypervisor2.1. Installing Red Hat Enterprise Virtualization Hypervisor You will need to install a Red Hat Enterprise Virtualization Hypervisor machine before configuring self-hosted engine on it. For more information on storage requirements, see Storage Requirements in the Installation Guide. To use the RHEV-M Virtual Appliance for the Manager virtual machine installation, the data partition (/data) must be at least 60 GB. 2.2. Configuring Self-Hosted Engine on Red Hat Enterprise Virtualization Hypervisor Once you have installed a Red Hat Enterprise Virtualization Hypervisor using the Hypervisor ISO, set up self-hosted engine using the screen. Self-hosted engine is currently supported on

In the Administration Portal, right-click the engine virtual machine, and select Enable Global HA Maintenance. You can also set the maintenance mode from the command line: # hosted-engine --set-maintenance --mode=global If the Manager virtual machine is down, start the Manager virtual machine. If the virtual machine is up, skip this step. # hosted-engine ---vm-start Set the console password: # hosted-engine --add-console-password# hosted-engine --console Determine why the Manager virtual machine is down or in a bad health state. Check /var/log/messages and /var/log/ovirt-engine/engine.log. After fixing the issue, reboot the Manager virtual machine. Log in to the Manager virtual machine as root and verfiy that the ovirt-engine service is up and running: # service ovirt-engine status After ensuring the Manager virtual machine is up and running, close the console session and disable the maintenance mode to enable the HA services again: # hosted-engine --set-maintenance --mode=noneAdditional Troubleshooting Commands: Contact the Red Hat Support Team if you feel you need to run any of these commands to troubleshoot your self-hosted engine environment. hosted-engine --reinitialize-lockspace: This command is used when the sanlock lockspace is broken. Ensure that the global maintenance mode is enabled and that the Manager virtual machine is stopped before reinitializing the sanlock lockspaces. hosted-engine --clean-metadata: Remove the metadata for a host's agent from the global status database. This makes all other hosts forget about this host. Ensure that the target host is down and that the global maintenance mode is enabled. hosted-engine --check-liveliness: This command checks the liveliness page of the ovirt-engine service. You can also check by connecting to in a web browser. hosted-engine --connect-storage: This command instructs VDSM to prepare all storage connections needed for the host and and the Manager virtual machine. This is normally run in the back-end during the self-hosted engine deployment. Ensure that the global maintenance mode is enabled if you need to run this command to troubleshoot storage issues. 4.2. Cleaning Up a Failed Self-hosted Engine Deployment If a self-hosted engine deployment was interrupted, subsequent deployments will fail with the following error: Failed to connect to broker, the number of errors has exceeded the limit.Chapter 6. Maintenance and Upgrading Resources6.1. Maintaining the Self-Hosted Engine The maintenance modes enable you to start, stop, and modify the engine virtual machine without interference from the high-availability agents, and to restart and modify the hosts in the environment without interfering with the engine. There are three maintenance modes that can be enforced: global - All high-availability agents in the cluster are disabled from monitoring the state of the engine virtual machine. The global maintenance mode must be applied for any setup or upgrade operations that require the engine to be stopped. Examples of this include upgrading to a later version of Red Hat Enterprise Virtualization, and installation of the rhevm-dwh and rhevm-reports packages necessary for the Reports Portal. local - The high-availability agent
