Are you configuring bonding directly through the OVS command line or using Xen tools? Can you also send the output of ovs-vsctl show? > Here is the complete output of the command.

OVS is definitely sending traffic to both ports. I suspect that for one reason or other it doesn't think those ports are bonded. >> Can you also post the logs? > > Well, there aren't much log files - at least not much I was able to find. > > --- cut --- > # ls -l /var/log/openvswitch > total 4 > -rw-r--r-- 1 root root 0 Jan 25 13:51 ovsdb-server.log > -rw-r--r-- 1 root root 0 Jan 25 13:51 ovs-vswitchd.log > -rw-r--r-- 1 root root 160 Jan 25 13:52 ovs-xapi-sync.log > # cat /var/log/openvswitch/ovs-xapi-sync.log > Jan 25 13:52:19|1|reconnect|INFO|unix:/var/run/openvswitch/db.sock: > connecting... > Jan 25 13:52:19|4|reconnect|INFO|unix:/var/run/openvswitch/db.sock: connected > --- cut --- It's also odd that the ovs-vswitchd.log file is empty. Can you check the command line to make sure that it is supposed to be logging? _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
