Added GATEWAY to ifcfg-eth0 example.
==Configure host bridge interfaces==
Steps 1 through 4 are done only once on the host.
1. (Optional) Verify that you can create a bridge interfaces for each physical interface on the host.
If the above commands do not work you may need to install the bridge-utils package.
2. Make note of the existing IP configuration in the hosts ifcfg-ethN files. Also, record the hardware MAC addresses of the ethernet interfaces from the output of 'ifconfig'. /sbin/ifconfig eth0 /sbin/ifconfig eth1 Then, modify the ifcfg-ethN files on the host so that they ONLY bridge to the corresponding brN interface. /etc/sysconfig/network-scripts/ifcfg-eth0 should look like:
DEVICE=eth0
NETMASK=yyy.yyy.yyy.yyy
ONBOOT=yes
GATEWAY=zzz.zzz.zzz.zzz
10. Initialize the interfaces and restart the network service on the container.
