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 Apr 27 11:05:14 hypervisor1 vdsm[2337]: WARN Attempting to remove a non existing net user: 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) Nico -- Nico De Ranter Operations Engineer T. +32 16 38 72 10 <http://www.esaturnus.com> <http://www.esaturnus.com> eSATURNUS Romeinse straat 12 3001 Leuven – Belgium T. +32 16 40 12 82 F. +32 16 40 84 77 www.esaturnus.com <http://www.esaturnus.com/> *For Service & Support * Support Line: +32 16 387210 or via email : support@esaturnus.com
