[ovs-discuss] gre tunnel create problem

[faicker mo]

I'm sorry, I have another question following this.
When I added the gre tunnel port on bridge, some errors occurred:
---------------------------------
56 Jun  4 18:33:42 archlinux ovs-vswitchd: 00062|dpif|WARN|system at br0: failed to add gre0 as port: Invalid argument
 57 Jun  4 18:33:42 archlinux ovs-vswitchd: 00063|bridge|WARN|netvm port has no interfaces, dropping
 58 Jun  4 18:33:42 archlinux ovs-vswitchd: 00064|bridge|INFO|destroyed port netvm on bridge br0
 59 Jun  4 18:33:42 archlinux ovs-vswitchd: 00065|bridge|WARN|bridge br0: using default bridge Ethernet address b6:8b:ef:f1:d6:41
--------------------------
Though the tunnel works. I found this because the tunnel port didn't appear in the "ovs-dpctl show" result.
