[ovs-discuss] vhost-user state in openvswitch

We bring 2 VMs up with vhost-user type. We can see eth0 interfaces created in 2 VMs with proper mac address we assign. After IP address assignment, 2 VMs could not PING to each other when they are in the same network segment.

However, we check link up state via ovs-ofctl utility but LINK_DOWN as below.

Have any one with experiences and give some helps ... Thanks!!!

$ sudo ./utilities/ovs-ofctl show ovsbr0
