Supporting Software - Expert Consolidation in Oracle Database 12c - page 124

■ oracle enterprise Manager Cloud Control 12c has support for oracle VM as well, but this is out of scope of
this chapter.

Note

After the initial installation of Oracle VM Server and Manager, the workflow to create a virtual machine in Oracle
VM Manager includes the following steps:

1. Discover Oracle VM Server(s).

2. Create a network to access the virtual machines.

3. Configure storage.

4. Create a new server pool.

5. Create a shareable repository to store installation files and virtual machines.

6. Create the virtual machine.

Let's look at these in more detail. Although the next steps seem quite complex and labor intensive, you have to say,
in fairness, that many tasks are one-time setup tasks.

Creating a Virtual Machine
The example to follow assumes that the infrastructure is already in place. In other words, you already have configured
SAN storage and networking. Oracle VM defines different types of networks, each of which can be assigned to a
network port. Link aggregation is also supported and can be configured in the management interface. In the following
example, the following networks have been used:

• 192.168.1.0/24: management network for server management, cluster management, and VM

live migration. This is automatically created and tied to bond0 on the Oracle VM Servers.
If possible, bond0 should be configured with multiple network ports.

• 192.168.100.0/24: used for iSCSI traffic and bound to bond1.

Shared storage is necessary to create a clustered server pool and to allow for migrations of virtual machines. It is
also possible to define server pools with local storage only, but, by doing so, you do not benefit from many advanced
features, especially VM migration.
The first step after a fresh installation of Oracle VM Manager and a couple of Oracle VM Servers (at least one must
be available) is to connect to the management interface, which is shown in Figure 4-4 .
