After further testing we can either get EM1 running on the bond or EM2 - EM4
running in the bond, but not EM1-EM4. We are running the Hosted Engine
Appliance in our setup. In order to install the appliance, i have to point
it to a physical nic during the install process. The install process
creates the network bridge ovirtmgmt which is tied to interface EM1 on both
servers. After i finished setting up the appliance, and both of my hosts, i
went in and created my bond so i could configure LACP.
It seems that is some disconnect between my network bridge, the bond and my
interfaces. I would like to some how get my bond to use all 4 interfaces.
On reboot, it always seems to reset consistently to EM1.

You should configure your LAG with this options (custom mode on oVirt):
mode=4 miimon=100 xmit_hash_policy=2 lacp_rate=1
An tell to your network admin configure switch:
"Give me lacp timeout short with channel-group mode active. Also set
port-channel load-balance src-dst-mac-ip (or src-dst-ip\src-dst-mac)".
You also need to understand that LACP balancing works 'per flow'. You can
take 2 hosts and run "iperf -c xxx.xxx.xxx.xxx -i 0.1 -d",
and on one phy interface you should see 1Gb RX, and on another phy interface
I discovered an issue with my LACP configuration and i am having trouble
figuring it out. I am running 2 Dell Powered 610's with 4 broadcomm nics.
I am trying to bond them together, however only one of the nics goes active
no mater how much traffic i push across the links.
I have spoken to my network admin, and says that the switch ports are
configured and can only see one active link on the switch.
