|Configure Eucalyptus / Configure Network Modes|
In System mode, Eucalyptus mostly stays out of the way in terms of VM networking, relying on your local DHCP service to configure VM networks. The NC has to specify a bridge, and that it is the bridge that is connected to an Ethernet network that has a reachable DHCP server running elsewhere that is configured to hand out IP addresses dynamically.
To configure for System mode:
No network configuration required.
VNET_MODE="SYSTEM" VNET_BRIDGE="<name of bridge on same network as the DHCP server. Example: xenbr0>"
