[Users] web gui and bonded nic changes
I hit a snag last night. I needed to remove a nic from a host bond in ovirtmanage to create a new bridge line for user access to VMs. The process hung the box and I had to go put hands on the physical console (more reason to get the ipmi network setup!). The error message was "can't add eth3 to bond. already bonded" (or close). It seems the only way to remove a nic from a bond is to unload the bonding module. Apparently the ovirt process doesn't call a modprobe -r bonding during a network reset on the managed hosts. stop network, unload bonding, start network worked fine from the console. -- -- James P.

Hi Jim, Could you provide me with the vdsm logs so I can get a better picture of what happened? Best, Toni ----- Original Message -----

... and please specify the version of your kernel and initscripts, as according to my experience echo -eth3 > /sys/class/net/bond0/bonding/slaves removes eth3 from bond0 with no need of `modprobe -r`.
Best,
