Hi all,
I bumped into a configuration error while trying to add a physical network
interface to a switch:
$ ovs-vsctl add-br myswitch
$ ovs-vsctl add-port myswitch eth9
ovs-vsctl: Error detected while setting up 'eth9': could not add network
device eth9 to ofproto (File exists). See ovs-vswitchd log for details.
ovs-vsctl: The default log directory is "/opt/oa/var/log/openvswitch".
Then I go to the specified log file and I don't see much more:
2018-04-20T14:26:05.226Z|00174|dpif|WARN|system@ovs-system: failed to add
eth9 as port: File exists
2018-04-20T14:26:05.226Z|00175|bridge|WARN|could not add network device
eth9 to ofproto (File exists)
The interface is up and bound to the correct driver:
# ip a show dev eth9
206: eth9: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master
ovs-system state UP group default qlen 1000
link/ether 00:90:0b:54:88:58 brd ff:ff:ff:ff:ff:ff
# ls -l /sys/class/net/eth9/device/driver
lrwxrwxrwx 1 root root 0 Apr 20 14:21 /sys/class/net/eth9/device/driver ->
../../../../bus/pci/drivers/igb
Deleting the port or the switch and re-doing the steps above won't help.
What am I missing here?
Here are more details from ovsdb:
