Hi,all
I get this problem with latest(dbd8112) branch-2.7 code on my Ubuntu.
root@ubuntu:/var/log/# ovs-vsctl show
adf2ea99-0c53-4180-914f-7dadaa71302b
Bridge test
Port test
Interface test
type: internal
Bridge "manage"
Port "manage"
Interface "manage"
type: internal
error: "could not open network device manage (File exists)"
Port "veth0"
Interface "veth0"
Port "eth0"
Interface "eth0"
ovs_version: "2.7.0"
How to reproduce:
1. add bridge "manage", up and add ip on it
2. restart ovs-vswitchd
3. "ovs-vsctl show" displays error message.
The reason:
In following "netdev_open" call on ovs-vswitchd start, input "type" is NULL
and "manage" is opened as a "system" netdev_class iface incorrectly.

#13 0x00000000004138ef in main (argc=1, argv=0x7fffffffe578) at
../vswitchd/ovs-vswitchd.c:119
After then, ovs fails to netdev_open "manage" with type == "internal".
"File exists" error is reported.
I think commit d3b8f50(netdev: Fix netdev_open() to adhere to class type if
given) introduces this problem. It need be improved.
Best wishes
