4.4 use gre tunnel failed

Hi all, When I use 4.4 GRE to isolate guest network, and cloudbr1 as the guest bridge, other traffic types on cloudbr0,
When I try to create vm, there is an exception as below. Isn't it the OVS controller auto creat OVSTunnel316 ?
And another question: is it no need to set SDN controller enable in global configuration, cause I only see the
"
| sdn.ovs.controller.default.label |
"
which I have set to cloudbr1

Re: 4.4 use gre tunnel failed

Hi,

Yes, OVS controller auto create OVSTunnelxxx. Please use ovs-vsctl ultility
to check if OVSTunnel316 is exists.

Use this guide:

Thanks,
