How to configure an Oracle VM Network

How do I Configure an Oracle VM Network?

When configuring a network via the Oracle VM Manager, one must map available network ports to the logical network. Each logical network requires a name or alias and performs at least one network function. Oracle VM has the following network functions:

• Server Management
• Cluster Heartbeat
• Live Migrate
• Storage
• Virtual Machine 

After discovering the first Oracle VM Server within the Oracle VM Manager, one network is created automatically with the role of Server Management. The default name provided comes from the subnet in which the Oracle VM Server is connected as seen below.

 
Figure 1: Oracle VM Network

Each additional Oracle VM Server discovered from the Oracle VM Manager either adds an entry into the
existing Server Management network or creates a new Server Management network if the server is connected to a subnet where no Oracle VM Server was previously discovered. 

Creating Oracle VM Networks

The steps listed in the Creating Virtual Machine Networks describe how to create a network and assign a
"Virtual Machine" role to it. Similarly, it is recommended to create different networks for the different network functions.

NOTE: It is recommended to have separate network port(s) for each function.
 
NOTE: Additional network is required when using iSCSI storage.

Creating Storage Network

After logging into the Oracle VM Manager console, click the Networking tab and Networks sub tab and add network by clicking "+" sign icon.

In the Create Network Wizard, select Create network with bond/ports only and click Next.

In the Create Network step of the wizard, enter name for the network and select the Storage in the Network Channels and click Next.

In the Select Servers step of the wizard, move the Oracle VM Servers to be included in the new network to the Selected Servers and click Next.

In the Select Ports step of the wizard, select Ethernet port from each Oracle VM Server and move them to the Select Ports field and click Next.

In the Configure IP Addresses step of the wizard, enter the IP addresses for storage networking and click Finish to create storage network.


Figure 7: Configure IP Addresses


NOTE: If you are using Compellent iSCSI create two storage networks for each fault domain and give the IP addresses configured in the previous step within the range of the fault domain’s IP address subnet.
Created Storage Networks will be displayed under the Networking tab.
