Don't focus on the boonding its transparent once configured.
Treat the bonded interface bondx like it was a ethx and the guides will make
sense.
I beleave off the top of my head the answer is apply the bridge to the vlan
interface unless you want the vlan tags to go to the vms and do 802.1Q on
the vms. I know running 802.1Q to a vm sounds crazy but I've seen it done to
"Off the top of my head the answer is apply the bridge" is not
helpful. I can google as well as the next engineer, better than most.
I need a precise answer, please. What do I need to tweak in
/etc/sysconfig/network-scripts/ifcfg-bond0.vlan1 to enable it not
merely as a VLAN, but as a bridge suitable for KVM virtualization? If
I'm forced to use the ifcfg-bond0 device as the KVM bridge, I'll be
forced to set up the VLAN configurations in the guest VM's and
that..... causes real adventures for kickstart and anaconda.
I use the following setup:
*** ifcfg-eth0 ***
DEVICE=eth0
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
plus identical config files for eth1 etc.
*** ifcfg-bond0 ***
DEVICE=bond0
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
BRIDGE=br0
BONDING_OPTS="miimon=1000 mode=4"
*** ifcfg-br0 ***
DEVICE=br0
TYPE=Bridge
BOOTPROTO=none
ONBOOT=yes
DELAY=0
*** ifcfg-bond0.100 ***
DEVICE=bond0.100
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
BRIDGE=vlan100
VLAN=yes
*** ifcfg-vlan100 ***
DEVICE=vlan100
TYPE=Bridge
BOOTPROTO=none
ONBOOT=yes
DELAY=0
#Add IP address here if required
#IPADDR=
#NETMASK=
#NETWORK=
#BROADCAST=
#GATEWAY=
Where the number after the dot in ifcfg-bond0.100 is the vlan id in the
usual way. The vlan100 device would then be the bridge device to select
for a kvm guest to get untagged traffic on vlan 100 to the guests nic.
Hope that helps.
Andrew
