ServerView Resource Orchestrator Cloud Edition V3.3.0 Design Guide

E.5.5 Network Preparations

Check the following:

• The configuration for the admin and public LANs has been designed

• The network environment for the admin LAN is configured

• The VLAN ID to allocate to the network resource has been configured

• The virtual bridge has been configured beforehand

• The MAC address range for the virtual network interface (VNIF) has been decided

Perform the following configuration:

• In order to enable the use of virtual bridges, disable the NetworkManager service of the OS.

  1. On the managed server, disable the NetworkManager service and then enable the network service.

     Execute the following command.

     # service NetworkManager stop <RETURN>
     # chkconfig NetworkManager off <RETURN>
     # service network start <RETURN>
     # chkconfig network on <RETURN>

  2. Edit the /etc/sysconfig/network-scripts/ifcfg-NIC_name file to change the value for NM_CONTROLLED to "no".

     Example

     • Before editing

       DEVICE="eth0"
       HWADDR="xx:xx:xx:xx:xx:xx"
       NM_CONTROLLED="yes"
       ONBOOT="no"
       BOOTPROTO=none

     • After editing

       DEVICE="eth0"
       HWADDR="xx:xx:xx:xx:xx:xx"
       NM_CONTROLLED="no"
       ONBOOT="no"
       BOOTPROTO=none

  3. Restart the managed server.

     Execute the following command.

     # shutdown -r now <RETURN>

• Perform configuration to allow the managed server to use the VLAN.

  1. Add "VLAN=yes" in the /etc/sysconfig/network file on the managed server using a text editor.

     Example

     • Before editing

       NETWORKING=yes
       HOSTNAME=localhost.localdomain

     • After editing

       NETWORKING=yes
       HOSTNAME=localhost.localdomain
       VLAN=yes

  2. Restart the managed server.

     Execute the following command.

     # shutdown -r now <RETURN>

• When using GLS for automatic network configuration, configure GLS.

  For details, refer to the GLS manual.

• Creating a virtual bridge

  Create a virtual bridge beforehand.

  
  

When Using IBP

When using virtual L-Servers, after creating the IBP uplink sets to use for the public LAN and admin LAN, connect the IBP uplink sets to the VM host.

It is not necessary to use the same name for the uplink set and the name of the network resource.

Creating a virtual bridge

The virtual bridge is required on the admin OS, in order to connect the L-Server to the network.

For details on how to configure virtual bridges, refer to the manual for RHEL-KVM and "8.6.4 Manual Network Configuration" in the "Setup Guide CE".
