Chapter 2. Enabling Red Hat Storage in Red Hat Enterprise Virtualization Manager
2.1. Using Red Hat Storage Volumes in the Red Hat Enterprise Virtualization Manager
Red Hat Enterprise Virtualization supports Red Hat Storage volumes as storage domains. Enabling Red Hat Storage volumes in Red Hat Enterprise Virtualization Manager requires installation and configuration of several components to create a functioning virtualization environment. You must install and configure each component in the following order:

Figure 2.1. Installation Workflow
Procedure 2.1. To Enable Red Hat Storage in Red Hat Enterprise Virtualization Manager
- Install Red Hat Enterprise Virtualization ManagerThe Red Hat Enterprise Virtualization Manager is the control center of the Red Hat Enterprise Virtualization environment. Ensure that Red Hat Enterprise Virtualization Manger is installed and configured.Install and configure Red Hat Enterprise Virtualization Manager. See the Manager Installation chapter of the Red Hat Enterprise Virtualization Installation Guide for more information.
- Install HostsInstall the virtual machine hosts using either Red Hat Enterprise Virtualization Hypervisor or Red Hat Enterprise Linux as hosts. Before beginning the installation process, ensure that all virtualization hosts meet the hardware requirements and that the installation of Red Hat Enterprise Virtualization Manager is complete.You can use the following hypervisors as hosts:
- Red Hat Enterprise Virtualization Hypervisor 3.4
- Red Hat Enterprise Linux 6.3
- Red Hat Enterprise Linux 6.4
- Red Hat Enterprise Linux 6.5
During installation, set the fully qualified domain name (FQDN) and IP address for the server in order to avoid network conflicts. See the Installing Red Hat Enterprise Virtualization Hypervisor Hosts chapter of the Red Hat Enterprise Virtualization Installation Guide for information on installing the hypervisor.Note
You must install Red Hat Enterprise Linux 6.3, Red Hat Enterprise Linux 6.4 Server or Red Hat Enterprise Linux 6.5 on a system to use it as a virtualization host in a Red Hat Enterprise Virtualization environment. See the Installing Red Hat Enterprise Linux Hosts chapter of the Red Hat Enterprise Virtualization Installation Guide or the Red Hat Enterprise Linux 6 Installation Guide for detailed instructions.Subscribe to the channelsRed Hat Enterprise Linux hosts need to be registered and subscribed to a number of entitlements using either Subscription Manager or Red Hat Network Classic. For more information, see section Subscribing to Required Channels using RHN Classic in the chapter Installing Red Hat Enterprise Linux Hosts in the Red Hat Enterprise Virtualization Installation Guide.Subscribe Red Hat Enterprise Linux 6.3, 6.4, and 6.5 hosts to the channels listed below:- rhel-x86_64-server-6
- rhel-x86_64-rhev-mgmt-agent-6
Apart from the above channels, you must also subscribe to the Red Hat Storage 3 Native Client channels to get the latest version:Run therhn-channel --add --channel
command to subscribe the system to the correct Red Hat Storage Native Client channel:- For Red Hat Enterprise Linux 7.x clients using Red Hat Satellite Server:
# rhn-channel --add --channel= rhel-x86_64-server-rh-common-7
- For Red Hat Enterprise Linux 6.x clients:
# rhn-channel --add --channel=rhel-x86_64-server-rhsclient-6
- For Red Hat Enterprise Linux 5.x clients:
# rhn-channel --add --channel=rhel-x86_64-server-rhsclient-5
See Installing Native Client in Red Hat Storage Administration Guide for information on how to install native clients. - Configure the Hypervisor
Red Hat Enterprise Virtualization Hypervisor host
Install Red Hat Enterprise Virtualization Hypervisor 3.4 on bare metal. See Configuring the Hypervisor and Attaching the Hypervisor to the Red Hat Enterprise Virtualization Manager in the Installing the Red Hat Enterprise Virtualization Hypervisor chapter of the Red Hat Enterprise Virtualization Installation Guide for more information.Red Hat Enterprise Linux 6.3, Red Hat Enterprise Linux 6.4 or Red Hat Enterprise Linux 6.5 host
A Red Hat Enterprise Linux virtualization host must be registered and subscribed to a number of entitlements using either Subscription Manager or Red Hat Network Classic. See Subscribing to Required Channels using RHN Classic in the Installing Red Hat Enterprise Linux Hosts chapter of the Red Hat Enterprise Virtualization Installation Guide for more information.Subscribe to the Red Hat Storage Native Client from the Additional Services Channels to ensure the server has the latest clients installed:#
See the Installing Native Client section in the Red Hat Storage Administration Guide for more information.yum install glusterfs-fuse glusterfs
- Configure the data centersDefine data centers and clusters to organize the virtualization hosts. The installation process creates a data center and associated cluster named
Default
.Note
A server can be a Red Hat Enterprise Virtualization Hypervisor or a Red Hat Enterprise Linux host. A trusted storage pool requires a minimum of one storage host, and at least one active virtualization host is required to connect the system to a storage pool. - Install Red Hat StorageInstall the latest version of RHS on the system.See section, "Prerequisites" of the Red Hat Storage Installation Guide for more information on obtaining the software. For information on installing Red Hat Storage from an ISO, see the Red Hat Storage Installation Guide.
- Configure StorageConfigure the Red Hat Storage installation for your requirements.For instructions on creating a Red Hat Storage Volume, see chapter Red Hat Storage Volume in the Red Hat Storage Administration Guide.Red Hat Enterprise Virtualization uses a centralized storage system for virtual machine disk images. Before adding storage, ensure that you have a working Red Hat Enterprise Virtualization Manager environment. You must be able to access the Administration Portal, and there must be at least one host connected with Up status.
Note
Red Hat Storage recommends that you use Replicate or Distributed Replicate volume type for hosting virtual machine disk images. - Attach Storage to HypervisorAttach the Red Hat Storage volume as a storage domain.
Now you can create virtual machines and its disk images on the Red Hat Storage volumes. To optimize the virtual machines on the Red Hat Storage volumes, see Section 2.2, “Optimizing Virtual Machines On Red Hat Storage Volumes”
