How to configure bridge over bonding in RHEL 6.4 Server?
There is an installed system ( rhel-server-6.4-x86_64-dvd.iso ). On top of which KVM is installed ( installation instructions ). The host machine and guest machine are assigned their own IP addresses, for this, according to the instructions from Habr, the br0 bridge is configured. Everything is working. Now we need to do bridge over bonding.
I put the following settings on the host:
[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=f0:92:1c:0f:76:f8
MASTER=bond0
SLAVE=yes
ONBOOT=yes
[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
HWADDR=F0:92:1C:0F:76:FC
MASTER=bond0
SLAVE=yes
ONBOOT=yes
[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
ONBOOT=yes
BRIDGE="br0"
[[email protected] ~]# cat /etc/modprobe.conf
alias bond0 bonding
options bond0 mode=1 miimon=100
[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE="br0"
