See ovs-vswitchd log for details. [DPTECH-Developer-Shell] 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. ________________________________ yugang From: Chandran, Sugesh<mailto:sugesh.chand...@intel.com> Date: 2016-03-21 17:03 To: yugang<mailto:yug...@dptechnology.net>; yugangdeai<mailto:yugangd...@163.com>; discuss<mailto:discuss@openvswitch.org> Subject: RE: Re: [ovs-discuss] userspace openvswitch 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.

I am really looking forward to hear from you. [Sugesh] No need to load ovs kernel module for userspace datapath. Best regards, Yugang .
