It seems that no datapath named 'ovs_datapath' exist.
So does you add bridge which type is 'ovs_datapath' already?
In OVS, default datapath type is 'ovs_datapath' or something.

We want to use it in userspace totaly, and this error is related to netlink and
kernel module, should not i ignore this error?

We have checked ‘INSTALL.userspace.md’ , it's same as version 1.11.0, and on
the same device, version 1.11.0 is ok,
here are tun module information:

We can also ignore this error msg?
[Sugesh] No, You are not supposed to get this error. Have you looked at ovs
logs??Please have a look at ‘INSTALL.userspace.md’ for detailed guide on how to
set up OVS in userspace. You might need to load tun/tap kernel module for
creating the bridge.

Specify the type of bridge as netdev for userspace bridge.
ovs-vsctl --timeout 10 add-br br0 -- set bridge br0 datapath_type=netdev
You can ignore the warning message “failed to enumerate ….” for now.
Verify if the bridge has been created successfully using ‘ovs-vsctl show’.

Dear there,
Thanks for your time, i want to know that whether the version 2.5.0
openvswitch can work in userspace totaly,
[Sugesh] 2.5.0 supports userspace datapath.
if it does, why i can add bridge with tool ovs-vsctl on version 1.11.0, but
failed on the latest version,
[Sugesh] What error you are getting?
which remind me to load the kernel module, how could i solve this problem. I am
really looking forward to hear from you.
[Sugesh] No need to load ovs kernel module for userspace datapath.
Best regards,
Yugang .
