Added note about case-sensitive Bridge TYPE and renamed openvz-centric bridge interface names to more generic names.
1. (Optional) Verify that you can create a bridge interfaces for each physical interface on the host.
/usr/sbin/brctl addbr vzbr0br0 /usr/sbin/brctl addbr vzbr1br1
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. Then, modify the ifcfg-ethN files on the host so that they ONLY bridge to the corresponding vzbrN brN interface. /etc/sysconfig/network-scripts/ifcfg-eth0 should look like:
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
BRIDGE=vzbr0br0
Similarly ifcfg-eth1 will look like:
BOOTPROTO=none
ONBOOT=yes
BRIDGE=vzbr1br1
Note that the ifcfg-ethN files on the host do not contain any IP information anymore.
3. Create ifcfg-vzbrN brN files and copy the IP configuration that was previously in the ifcfg-ethN files into ifcfg-vzbrNbrN. Here's what host:/etc/sysconfig/network-scripts/ifcfg-vzbr0 br0 would look like assuming the IPv4 address is assigned statically and IPv6 auto-configuration (SLAAC) is used:
DEVICE=vzbr0br0
BOOTPROTO=static
IPADDR=xxx.xxx.xxx.xxx
NETMASK=aaa.aaa.aaa.aaa
ONBOOT=yes
TYPE=bridgeBridge
Similarly, ifcfg-vzbr1 br1 should look like:
DEVICE=vzbr1br1
BOOTPROTO=static
IPADDR=yyy.yyy.yyy.yyy
NETMASK=bbb.bbb.bbb.bbb
ONBOOT=yes
TYPE=bridgeBridge
Note that TYPE 'Bridge' is case-sensitive. 4. On the host, do a 'service network restart' and verify the host has both IPv4 and IPv6 connectivity to its vzbrN brN interfaces.
