[ovs-discuss] ovs-ofctl prints "br0 is not a bridge or socket" and doesn't work

[JinHwan Hwang]

No, i didn't insert kernel module. But i thought i didn't need to insert
kernel module if i want to use user space
OVS. Do i misunderstand INSTALL document?

I didn't got this message from kernel module inserted OVS servers.
