Hi,

I'm trying to setup an Ovirt 4.2.2 host (CentOS based) with a network bond containing 2 network interfaces.  I need to use an active-passive network setup as my switch doesn't seem to like the XOR mode.  I tried updating my /etc/sysconfig/network-scripts/ifcfg-bond0 file manually to set

     BONDING_OPTS='mode=1 miimon=100'

however each time I reboot the file gets reverted to mode=2 by vdsm.  I tried setting

     hidden_bonds=bond0

in /etc/vdsm/vdsm.confm but now my hosted-engine doesn't want to start anymore. I assume because by doing that I basically disabled the network for my VM's completely.  /var/log/messages shows:

Apr 27 11:05:14 hypervisor1 vdsm[2337]: WARN Attempting to remove a non existing network: ovirtmgmt/14ad9ae1-d9a2-4ca4-8120-948f41e3a5b9

How can I change the type of network bond I want to use?    I found a nice tutorial video on the ovirt website showing an interface that would allow me to make a bond and set it to the type I need, but I cannot find that GUI anywhere on my system (does it even exist in 4.2.2? The webinterface in the videos looks totaly different than what I am seeing)

Hi, 

this can be done via the web UI. Go to Compute -> Hosts. Here click on the name of host you want to configure bond on. Then Network Interfaces -> Setup Host Networks. Here you should see your bond, by clicking on the pencil you should be able change the bond mode. 

Hopefully this helps. 

Regards,
Ales.
