Configuring Container Network Parameters

The Network Configuration page lets you define all the major network parameters of the Container you are creating.

The first thing to be decided upon is whether the network connectivity for the Container should be provided in the host-routed or bridged mode. You can also have both types of network interfaces in the Container.

The host-routed mode is simpler, no additional configuration of the Virtuozzo network is required for the created Containers to be immediately connected to the network. This mode is sufficient in most cases. However, the host-routed Containers cannot get their IP addresses by DHCP because their Virtual Network adapter does not have a unique MAC address.
In the bridged mode, a Container is a full member of the network. However, a bridged Container must always belong to a Virtual Network that would provide the network connectivity for the Container. Virtual Networks are created and configured separately. So, at least one Virtual Network should be already configured on the Hardware Node for you to be able to use the bridged network mode for the Container being created. The bridged mode also allows you to create more than one virtual Ethernet adapter in the Container (click the Add New Interface link for this).

After you have selected either the Routed Network or Bridged Network checkbox (or both), you should indicate the IP parameters of the relevant interfaces (together with the parameters in the Global Network group that pertain to all the Container network interfaces, be they host-routed or bridged):

Parameter	Description
DNS Server IP Address	One or more DNS servers to be used by the Container virtual adapters. For Linux-based Containers, all the DNS servers are common for all the Container virtual adapters. In Windows-based Containers, each virtual adapter can have its own DNS server. Note that the static values in these fields might be overridden if the Container gets the DNS servers from the DHCP server when operating in the bridged network mode.
WINS Server IP Address	One or more WINS servers to be used by the Container virtual adapters. Each virtual adapter can be assigned its own WINS server.
Search Domain	One or more search domains to be used by the Container virtual adapters. All the search domains are common for all the Container virtual adapters. Note that the static values in these fields might be overridden if the Container gets the search domains from the DHCP server when operating in the bridged network mode.
IP Address/Subnet Mask	One or more IP addresses and subnet masks of the Container virtual adapter. In the bridged mode, if the Get IP Address by DHCP checkbox is selected, you do not have to provide an IP address for the Container; it will be assigned automatically by your DHCP server once the Container is started.
Connect to [Virtual Network]	On this drop-down menu, you should select the Virtual Network to which the Container will be assigned, if you use the bridged network mode.
Default Gateway	If you want the Container to operate in the bridged mode and not use a DHCP server, you should indicate the default gateway for it.
