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@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.
