C.3.3 Flow for selecting the virtual network configuration in each redundant line switching mode

Use the following flowchart to select the virtual network configuration for each redundant line switching mode.

Configuration 1: Configuration for creating a highly reliable network of guest domains using GLS on domain-0

Use this configuration when you want guest domains to maintain communications without being aware of network failures and without clustering guest domains. Also, set the NIC switching mode or Virtual NIC mode for domain-0 (host OS).

Configuration 2: Configuration for creating a highly reliable network on guest domains of a single system

Use this configuration when you want to detect an error on each guest domain in the even of a network failure without clustering guest domains. Note that the Fast switching mode, NIC switching mode, or Virtual NIC mode can be set for each guest domain (guest OS) in this configuration.

Configuration 3: Configuration for creating a highly reliable network on guest domains of a cluster system

Use this configuration when you want to cluster guest domains. Note that the Fast switching mode, NIC switching mode, or Virtual NIC mode can be set for each guest domain (guest OS) in this configuration.
