5.1.1 Create New Network

To create a new Network

  1. On the Networking tab, click the Networks subtab.

  2. Click the Create New Network icon Create a New Network icon . A dialog is displayed with the following two options:

    • Create a Network with Ports/Bond Ports/VLAN Interfaces: Use this option to create a normal network that makes use of physical ports, bond ports or VLAN Interfaces defined on your servers.

      Note

      If you have not already defined any VLAN interfaces as described in Section 5.2, “VLAN Interfaces”, you are unable to add any VLAN interfaces to the network. In other words, you must define your VLAN interfaces on the VLAN Interfaces subtab before attempting to add any VLAN interfaces to a network.

    • Create a Local Network on a single server: Use this field to create a virtual network running on a single Oracle VM Server, usually to facilitate communication between virtual machines running on that server.

  3. Click Next to begin one of the following procedures:

Create a Network with Ports/Bond Ports/VLAN Interfaces

  1. After you select a network configuration, the Create Network wizard displays the following fields to configure your network:

    • Name: The name of the network in Oracle VM Manager.

    • Description: Optional information you would like to add about this network.

    • Network Uses: A set of check boxes that allow you to define the various network roles or channels that are enabled on the network.

      • Management: Used to manage the physical Oracle VM Servers in a server pool, for example, to update the Oracle VM Agent on the different Oracle VM Servers. This network function is assigned to at least one network by default.

      • Live_Migrate: Used to migrate virtual machines from one Oracle VM Server to another in a server pool, without changing the status of the virtual machine.

      • Cluster_Heartbeat: Used to verify if the Oracle VM Servers in a clustered server pool are up and running.

      • Virtual_Machine: Used for the network traffic between the different virtual machines in a server pool.

      • Storage: Enables you to associate specific networks with storage use.

    Click Next to continue to the next stage of the wizard, or click Cancel to exit the wizard without making any changes.

  2. The Select Ports stage of the wizard is displayed. This dialog allows you to define which ports or bonds on each Oracle VM Server are attached to the network and presents a tabular view of ports and bonds that are attached to the network.

    Note

    If you only wish for your network to contain VLAN interfaces, there is no requirement for you to add any network ports to the network in this dialog. You are able to add VLAN interfaces to the network in the next stage of the wizard.

    At the top of the table is a toolbar containing options to Add New Ports icon Add New Ports, Edit Port(s) icon Edit Port(s), or Delete Port(s) icon Delete Port(s).

    To Add A Port To The Network

    1. Click the Add New Ports icon Add New Ports icon at the top of the table.

      Note

      Only ports that are not bonded are displayed. Once a port is part of a bond, it can no longer be used outside of that bond.

    3. Click OK to add the ports that you have selected, or click Cancel to exit without any changes.

    To Edit A Port Within The Network

    1. Select the port or ports that you wish to edit within the network.

    To Delete A Port From The Network

    1. Select the port or ports that you wish to remove from the network.

    2. Click the Delete Port(s) icon Delete Port(s) icon.

    3. The Delete Confirmation dialog box is displayed. Click OK to delete the port from the network.

    When you have finished defining the ports that belong to the network, you can click Next to continue to the next stage of the wizard, or click Cancel to exit the wizard. Note that if you only wish for your network to contain VLAN interfaces, there is no requirement for you to add any network ports to the network in this dialog, as you are able to add VLAN interfaces to the network in the next stage of the wizard.

  3. The Select VLAN Interfaces stage of the wizard is displayed. This dialog allows you to define which VLAN interfaces on each Oracle VM Server are attached to the network and presents a tabular view of VLAN interfaces that are attached to the network. Note that in order to add a VLAN interface to a network it must have been defined prior to starting this wizard, as described in Section 5.2, “VLAN Interfaces”. At the top of the table is a toolbar containing options to Add VLAN Interfaces icon Add VLAN Interfaces, Edit VLAN Interface(s) icon Edit VLAN Interface(s), or Delete VLAN Interface(s) icon Delete VLAN Interface(s).

By clicking on the different nodes in this panel, you are able to update the tabular view of the different available VLAN interfaces on the right.

      Note that if you have not already defined any VLAN interfaces as described in Section 5.2, “VLAN Interfaces”, no VLAN interfaces are displayed in this view and you are unable to add any VLAN interfaces to the network. In other words, you must define your VLAN interfaces on the VLAN Interfaces subtab, before attempting to add any VLAN interfaces to a network.

    3. Identify the VLAN interfaces that you wish to add to the network and check the check box alongside them.

    4. Click OK to add the selected VLAN interfaces to the network, or click Cancel to exit without making any changes.

    4. For each VLAN interface listed, you are able to edit the MTU setting, and the IP Address assignment settings.

    5. Click OK when you have finished editing VLAN interfaces to save the changes, or click Cancel to exit.

    To Delete A VLAN Interface From The Network

    1. Select the VLAN interfaces that you wish to remove from the network.

    2. Click the Delete VLAN Interface(s) icon Delete VLAN Interface(s) icon.

    3. The Delete Confirmation dialog box is displayed. Click OK to delete the VLAN interface from the network.

    When you have finished adding any VLAN interfaces to the network, you are able to click Finish to save the new network configuration. Alternatively, you can click Cancel to exit the wizard without saving the network changes. Note that if you edited the configuration for a Port, Bond or VLAN interface in any of the sub-wizards, these changes have already been effected.
