This configuration is the same as the one described in "C.4.2 Configuration for creating a highly reliable network on guest domains of a single system (Configuration 2)". You can maintain communications in the event of a one-sided network failure. Additionally, you can take over the virtual IP address in the event of a both-sided network failure. The failover operation is the same as when a physical server is used. For more details, see "5.4 Operation on cluster systems".
