66 Appendix: Emulated Ethernet NIC Notes
9 Appendix: Emulated Ethernet NIC Notes
A hypervisor hosting a VSC VM is expected to have two bridge interfaces used to attach the
VSC management and datapath NICs. This appendix shows an example configuration for the
bridge interfaces and associated NICs.
In the procedure and sample output below, eth0 is associated with br0, and eth1 is associated
with br1. The Ethernet to bridge mappings can be customized according to your hardware and
network configuration. If the device associations are different, make appropriate adjustments to
the procedure.
The information needed for the installation is:
• The interface names for the management and datapath interfaces on the hypervisor
• The IP addresses and network information (including default route) for the management
and datapath interfaces on the hypervisor
The files that will be modified are:
• /etc/sysconfig/network-scripts/ifcfg-eth0
• /etc/sysconfig/network-scripts/ifcfg-eth1
• /etc/sysconfig/network-scripts/ifcfg-br0
• /etc/sysconfig/network-scripts/ifcfg-br1
The procedures are:
• Modify the eth0 configuration
• Modify the eth1 configuration
• Edit (or create) the br0 configuration
• Edit (or create) the br1 configuration
