3.4. Configuring Network

Virtuozzo Infrastructure Platform requires one network interface per server for management. On the Component Installation screen, you will need to specify a network interface to which to assign the network with the Internal management traffic type. After installation, you will not be able to remove this traffic type from the preconfigured network in the admin panel.

On the NETWORK & HOST NAME screen, you need to have at least one network card configured. Usually network is configured automatically (via DHCP). If manual configuration is required, select a network card, click Configure…, and specify the necessary parameters.

It is recommended, however, to create two bonded connections as described in Planning Network and create three VLAN interfaces on one of the bonds. One of the VLAN interfaces must be created in the installer and assigned to the admin panel network so that you can access the admin panel after the installation. The remaining VLAN interfaces can be more conveniently created and assigned to networks in the admin panel as described in the Administrator’s Guide.

In addition, you can provide a unique hostname, either a fully qualified domain name (<hostname>.<domainname>) or a short name (<hostname>), in the Host name field. If do not, a unique hostname will be generated automatically by the installation program.

3.4.1. Creating Bonded Connections

Bonded connections offer increased throughput beyond the capabilities of a single network card as well as improved redundancy.

You can create network bonds on the NETWORK & HOSTNAME screen as described below.

  1. To add a new bonded connection, click the plus button in the bottom, select Bond from the drop-down list, and click Add.

  2. In the Editing Bond connection… window, set the following parameters for an Ethernet bonding interface:

    1. Mode to XOR.
    2. Link Monitoring to MII (recommended).
    3. Monitoring frequency, Link up delay, and Link down delay to 300.

    Note

    It is also recommended to manually set xmit_hash_policy to layer3+4 after the installation.

  3. In the Bonded connections section on the Bond tab, click Add.

  4. In the Choose a Connection Type window, select Ethernet from the in the drop-down list, and click Create.

  5. In the Editing bond slave… window, select a network interface to bond from the Device drop-down list.

  6. Configure MTU if required and click Save.

  7. Repeat steps 3 to 7 for each network interface you need to add to the bonded connection.

  8. Configure IPv4/IPv6 settings if required and click Save.

The connection will appear in the list on the NETWORK & HOSTNAME screen.

3.4.2. Creating VLAN Adapters

While installing Virtuozzo Infrastructure Platform, you can also create virtual local area network (VLAN) adapters on the basis of physical adapters or bonded connections on the NETWORK & HOSTNAME screen as described below.

  1. To add a new VLAN adapter, click the plus button in the bottom, select VLAN from the drop-down list, and click Add.

    ../_images/stor_install6.png
  2. In the Editing VLAN connection… window:

    1. Select a physical adapter or bonded connection the VLAN adapter will be based on from the Parent interface drop-down list.
    2. Specify a VLAN adapter identifier in the VLAN ID field. The value must be in the 1-4094 range.

  3. Configure IPv4/IPv6 settings if required and click Save.

The VLAN adapter will appear in the list on the NETWORK & HOSTNAME screen.
