Centos6.4 - lacp (bond 4) + bridge setup
I followed the Centos 6.4 KVM howto, and it worked perfect. I setup QEMU on a Slackware box to admin the guest, and that works great too.
I was wondering if anyone has any experience with setting up LACP (802.3ad dynamic link aggregation) & a bridge for use with KVM.
I have a HP ML370 with 2 x gigabit nics that I installed Centos 6.4 & KVM (virgin run with KVM). To keep it simple I just configured 1 nic, and setup a bridge (as the docs recommended). This setup worked fine. I was able to access the host & the guests no problem.
I would like to take advantage of both nics on the server & would like to setup LACP (bonding mode 4) + the Bridge. I am no stranger to LACP, and all my servers with more than 2 nics are setup this way. No problem.
The problem I am having is getting the bonded links to work with the bridge. Does anyone know how to do this? I currently have the bond 4 working, and can confirm on the switch that LACP partnership is active & up. I cannot ping/access the guests anymore, and the guests (using the bridge) cannot access anything.
Here are my config files:
Up to this point bonding works, I can ping the host, and the host can access outbound.
When I originally configged the KVM bridge I called it br0, so I would like to keep this name so I don't have to redo everything.
Some of the docs online mention I need to setup a tagged vlan on the switch for this config. Is this true, do I really need a vlan?
I did setup a tagged vlan (vlan11), and added the following ifcfg files, but no dice.
So, do I really need a vlan setup on the switch for this config?
If not I suppose I can ditch the ifcfg-bond0.11 config file, and remove the tagged vlan from the switch? If this is the case, can I simply add BRIDGE=br0 to the bond0 config, and remove the VLAN & STP from the br0 config?
Any insight on this would be greatly appreciated.
