6 Deploying Cloud Infrastructure Services

This section provides the detailed actions performed to configure Red Hat products that

constitute the infrastructure used for a private cloud.

The goal is to create a set of highly available cloud infrastructure management services and

the initial cloud hosts. The cloud management services and initial hosts are used in the next

section to configure additional cloud hosts, VMs within the hosts, and load applications within

those VMs.

High availability is achieved by clustering two RHEL nodes using RHCS. Each of the cluster

nodes is configured to run RHEL 5.5 with the bundled KVM hypervisor. Each cluster member

is provisioned using the environment's RHN Satellite VM. One of the blades (that later

becomes a member of the cluster) is temporarily installed with RHEL to host the RHN

Satellite with which to provision the cluster members. For the majority of the management

services, a VM is created using the KVM hypervisor and configured as an RHCS service. The

management service is then installed in the VM (e.g., RHN Satellite VM, JON VM). A high

level walk-through of the steps to create these highly available cloud infrastructure

management services is presented below.

1. Install RHEL + KVM on a node

2. Create a VM

3. Install RHN Satellite in the VM (Satellite VM)

4. Synchronize Satellite with RHN & download packages from all appropriate channels /

child channels:

• Base RHEL 5

• Clustering (RHCS)

• Cluster storage (GFS2)

• Virtualization (KVM)

• RHN Tools

• MRG

• RHEV management agents for RHEL hosts

5. Use multi-organization support in Satellite - create tenant and infrastructure

organizations

6. Configure cobbler

• Configure cobbler’s management of DHCP

• Configure cobbler’s management of DNS

• Configure cobbler’s management of PXE

7. Provision MGMT-1 node from Satellite

8. Migrate the Satellite VM from temporary node to MGMT-1

9. Provision additional cloud infrastructure management VM services on MGMT-1

• Windows VM: RHEV-M

• RHEL VM: JON

• RHEL VM: MRG Manager
