Standalone Manager installation is manual and customizable. You must install a Red Hat Enterprise Linux machine, then run the configuration script (
engine-setup) and provide information about how you want to configure the Red Hat Virtualization Manager. Add hosts and storage after the Manager is running. At least two hosts are required for virtual machine high availability.
In a remote database environment, you must create the Manager database manually before running
engine-setup. You can create the Data Warehouse database manually, or let the Data Warehouse configuration script (
ovirt-engine-dwh-setup) create it automatically if you are installing the Data Warehouse service on the same machine.
See the Planning and Prerequisites Guide for information on environment options and recommended configuration.
Table 1. Red Hat Virtualization Key Components
Red Hat Virtualization Manager
A service that provides a graphical user interface and a REST API to manage the resources in the environment. The Manager is installed on a physical or virtual machine running Red Hat Enterprise Linux.
Red Hat Enterprise Linux hosts (RHEL-based hypervisors) and Red Hat Virtualization Hosts (image-based hypervisors) are the two supported types of host. Hosts use Kernel-based Virtual Machine (KVM) technology and provide resources used to run virtual machines.
A storage service is used to store the data associated with virtual machines.
A service that collects configuration information and statistical data from the Manager.
Standalone Manager Architecture
The Red Hat Virtualization Manager runs on a physical server, or a virtual machine hosted in a separate virtualization environment. A standalone Manager is easier to deploy and manage, but requires an additional physical server. The Manager is only highly available when managed externally with a product such as Red Hat’s High Availability Add-On.
The minimum setup for a standalone Manager environment includes:
- One Red Hat Virtualization Manager machine. The Manager is typically deployed on a physical server. However, it can also be deployed on a virtual machine, as long as that virtual machine is hosted in a separate environment. The Manager must run on Red Hat Enterprise Linux 7.
- A minimum of two hosts for virtual machine high availability. You can use Red Hat Enterprise Linux hosts or Red Hat Virtualization Hosts (RHVH). VDSM (the host agent) runs on all hosts to facilitate communication with the Red Hat Virtualization Manager.
- One storage service, which can be hosted locally or on a remote server, depending on the storage type used. The storage service must be accessible to all hosts.
