You create a VM Network channel in Oracle VM Manager to enable Oracle VM Guests in the server pool to communicate with each other and also to communicate with external networks. The VM Network channel instructs Oracle VM Servers to create a Xen bridge that controls network traffic to and from Oracle VM Guests.
A Server Management Network channel that enables communication between Oracle VM Manager and Oracle VM Servers is automatically created by Oracle VM Manager. You can use this existing Server Management Network channel to communicate with virtual machines, or create a new network channel.
Note:
Oracle recommends that you create a new network channel for the virtual machines.
To create a VM Network Channel, follow the procedures described in one of the following topics:
Using the Existing Server Management Network Channel for Virtual Machines
For simple network deployments, you can use the default Server Management Network channel to communicate with virtual machines.
To use the Existing Server Management Network channel for Virtual Machines:
Log on to Oracle VM Manager.
Select the Networking tab.
Select the Server Management Network channel address.
Note:
The Server Management Network channel address is similar to the Gateway address you entered except the trailing digit at the end of the address is a zero. For example, if you entered 10.244.138.1 as the Gateway address, the Server Management Network channel address is displayed as 10.244.138.0.
Click the Edit icon.
The Edit Network screen in displayed.
To enable the virtual machine to connect the Server Management Network channel, select Virtual Machine.
Click Next.
Accept the default server settings, and click Next.
Accept the default port settings, and click Next.
Click Finish.
The Virtual Machine column against the Server Management Network channel address displays a check mark indicating that the virtual machine is connected to the network.
Creating a New Network Channel for Virtual Machines
Before you can create a new network channel you must connect additional Ethernet cable to the Gigabit Ethernet connector ports and create a new bonded port through the Oracle VM Manager user interface.
Note:
The following procedure describes how to create and use a bonded port for the network channel. If you need to, you can use a single ethernet port for the channel instead of a bond. Oracle recommends using a bonded port.
To create a new bonded port and network channel:
Log on to Oracle VM Manager.
Select the Servers and VMs tab.
To create a new bonded port, perform the following tasks:
In the left pane, expand Server Pools, and then select the Exalytics Machine on which the Oracle VM Server is running.
In the Perspective list, select Bond Ports.
Click Create Bond Port.
The Create Bond Port page is displayed.
In the Addressing list, select IP Address.
In the IP Address field, enter an IP address for the bond.
In the Mask field, enter a Netmask for the bond.
Leave the MTU field at the default number.
Enter a description for the bond.
In the Available Ports section, select the connected ports and move it to the Selected Ports section.
Click OK.
To create a new network channel, perform the following tasks:
Select the Networking tab.
Click Create New Network.
The Create Network page is displayed.
Select Create a network with bond/ports only, and click Next.
In the Name field, enter a name for the network.
Enter a description.
Select Virtual Machine, and then click Next.
In the Available Servers section, select the server on which the Oracle VM Manager is running, move it to the Selected Servers section, and then click Next.
In the Available Ports section, select the bonded port you created in Step 3, move it to the Selected Ports section, and then click Next.
The Ports page is displayed.
Confirm the settings on the Ports page and then click Finish.
