This section helps you get started with this chapter by providing an overview of the steps involved in setting up the virtualization infrastructure. Consider this section to be a documentation map to understand the sequence of actions you must perform to successfully set up virtualized systems.

1. Before you start monitoring and managing virtualization targets, you must register the Oracle VM Manager with Oracle Enterprise Manager. See Registering the Oracle VM Manager 3.4x for details.

2. You can then discover one or more Oracle VM Server targets. See Discovering a Virtual Server for details.

3. Set up the storage infrastructure for the cloud. See Registering Storage Servers for details.

4. Configure networks and VLAN Groups. See Setting Up Networks for details.

   If you are using Oracle VM Manager 3.3, you must configure the VLAN Interface. See Creating a VLAN Interface for Oracle VM Manager 3.4

5. Create a virtual server pool. See Creating a Virtual Server Pool for details.

6. Create a zone by grouping one or more server pools. See Creating a Zone for details.

Figure 4-1 shows the sequence of steps involved in setting up the virtualization infrastructure.

Enterprise Manager can monitor the OVM Manager and the various virtualization targets registered with the OVM Manager. The targets registered with the OVM Manager must also be monitored targets in Enterprise Manager. If some targets have been created directly in OVM Manager, you can synchronize them in two ways:

• Automatically Synchronizing the Oracle VM Manager Targets

• Manually Synchronizing the Oracle VM Manager Targets

1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.
2. Click on an OVM Manager target from the left panel to navigate to the OVM Manager Home page. From the VM Manager menu, select Discover Virtual Server.

   Figure 4-4 Discover Virtual Servers

   
   
   
3. Specify the host name or the IP address of the virtual server. You can enter multiple host names or IP addresses on separate lines.
4. Enter the user name and password of the Oracle VM Agent running on the virtual server to be discovered.
5. Click Submit to discover the virtual server.

1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.
2. Right click on a Virtual Server target in the left panel and select Rediscover Virtual Server.
3. A confirmation message appears. Click OK to rediscover the virtual server and discover any new NICs and LUNs that have been added.

This section discusses creation and use of Oracle VM Networks. You can define a name or an alias for each logical network. When you have created your networks, you connect the physical network ports on Oracle VM Servers to the logical networks. Before you define the logical networks in Enterprise Manager, you have to review your physical network configuration that you intend to use, such as VLAN and subnet usage. Setting up an Oracle VM network involves:

• Generating MAC Addresses

• Creating a VLAN Interface for Oracle VM Manager 3.4

• Creating Networks

  Figure 4-5 Setting Up Networks

  
  

  

  
  

  Note:

  In Oracle VM Manager 3.3, VLAN Groups have been replaced with VLAN Interfaces. When you are configuring the VLAN Interface, you are prompted for the VLAN Segment IDs and the ports on which the interfaces are to be created.

1. From the Setup menu, select Provisioning and Patching, then select Network Profile.
2. Click Create on the Network Profile page.
3. Enter the following details in the Create Network Profile pop-up window:

   Figure 4-9 Create Network Profile

   
   

   

   
   

   • Name: Unique name that identifies the network profile name.

   • Domain Name: Domain for which the profile is being defined. The domain name must not begin with a dot ('.'). For example, you must specify the domain name as us.example.com and not with a dot ('.) in the front like .us.example.com.

   • Netmask: Network mask for the subnet IP. For example: 255.255.240.0

   • Gateway: Gateway for the IP address list.

   • DNS Servers: Name resolution servers.

4. You can add a list of IP addresses or specify a range. If you select:

   • List: Specify IP addresses with host name and MAC address (optional).

   • Range: Specify a Hostname Pattern. The Start Value is appended to the host names generated. The First IP Address and the Last IP Address defines the range. For example: If the pattern is say hostprod and Start Value is 1, First IP Address is 10.1.1.1 and Last IP Address is 10.1.1.3, the host names will be hostprod1, hostprod2 and hostprod3.
